Irrigation Controller (up to 16 valves with Shift Registers)

[Lars65]

Is it anybody who has this skecht in 24 hour format, instead of AM, PM?

[petewill]

@Lars65 Take a look at lines 663-667. I haven't tested this but it should be something similar to this:

          lcd.print(hour() < 10 ? F(" ") : F(""));
          lcd.print(hour());
          lcd.print(minute() < 10 ? F(":0") : F(":"));
          lcd.print(minute());
          //lcd.print(isAM() ? F("am") : F("pm"));

[Sergio Rius]

Does anyone already made a pcb for this? My board keeps loosing it's "bridging" wires. They rot and fall near the solder.

[Lars65]

@petewill I did try this, and it worked just fine. Thank you!

[petewill]

@Sergio-Rius Where do you have your controller located? I have had mine running for over a year now and haven't had any issues. Maybe you need to put it into a waterproof case?

To answer your question though, no, I don't believe anyone has created a PCB for this.

[Lars65]

I will have mine in the greenhouse. Boxes is made of waxed oak,and it will be 3 modules, each one seald with a sillicone gasket.
I have some trash wood in the garage, so I thought I could use it to something.

[Lars65]

Have anyone compiled it with the 2.0.0?

Hello Gentlemen, new to this board as well as new to micro electrics. Started this Irrigation Controller about a two weeks ago, after finding Pete B’s U tube video on this project. Got all the parts and have started building by following Pete B’s video. Have a few part questions and am not very literal with the nomenclature.

1. This 4.7uF 50V 20% Axial-Lead Electrolytic Capacitor goes on which end or pins on the
2. Have a FT232RL FTDI USB 3.3V 5.5V to TTL Serial Adapter Module for Mini Port that is different than Pete’s.
   Not sure how to post JPEG's so this is the problem I am having.
   0_1468546122072_7-14-16 Hello Gentlemen help.docx
   The Pins on the ftdi are different than on Pete’s board, in that I cannot find the info for the double GND on the Arduino Pro Mini.

Any guidance of will be appreciated.
Respectfully RJ Myers

[petewill]

@Lars65 No, not yet. It's on the list but it will probably be a little while before I get to it.

@Ngwpower To add pictures you just have to drag and drop into the edit window. They will automatically upload.

1. Can you provide more info here? I'm not sure what you're asking.

2. Both of my FTDI adapters connect into the Pro Mini straight across (the wires don't get crossed when connecting. The key thing is TX on one side should go to RX on the other (and vice versa) then the other 4 wires line up from there. So, you almost have it correct in your picture but the TX and RX are switched. Just start from the DTR and go straight across.

[A Former User]

Thank You, petewill I adjusted the wiring!

This is the picture for the 4.7 UF that has me baffled of where to insert into the radio. Being color blind really hurts with wiring. And rather ask than fry another project....

@Ngwpower

EDIT: My condenser is 10uF / 63v

[Sergio Rius]

Does this sketch still work with the current Mysensors libraries?
I lost my working environment so I had to build a new one. I downloaded the MySensors libraries and the sketch throws me an error not finding MySensor.h. The file is not at the libraries folder, but MySensorS.h
If adding this later (used at the samples) the compilation throws an error:

W:\....\MySensors_Arduino\arduino-1.6.9\portable\sketchbook\libraries\MySensors/MySensors.h:287:4: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

   #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

    ^

exit status 1
Error compilación en tarjeta Arduino Nano.```

Does make sense for anyone?

[A Former User]

@Sergio-Rius
Than You for the clarfication & picture worth thousands of words.
RJ

[petewill]

@Sergio-Rius Hmm. Are you using the 2.0 release? If so then it's not compatible yet. It still needs to be upgraded.

[A Former User]

Got the controller all ready to test like petewill shows in his presentation. Get this error
MySensors-1.5.4 loaded it onto my board Arduino Pro Mini and get this error -*** F:\Arduino Programs\My sensors downloads\upload-9cc672c5-a5a3-4711-9e38-8f3f7da898a5\upload-9cc672c5-a5a3-4711-9e38-8f3f7da898a5.ino:33:19: fatal error: Relay.h: No such file or directory***
Can I see this operate on my screen, without all the advanced technology? Found the Domoticz site and no sure if this is for me anymore than the Vera that is being used by petewill. Way out of my knowledge base with this project, just to stubborn to quit or give up.

[Lars65]

@Ngwpower which sketch are you using?

[A Former User]

@Lars65 Thanks

[Lars65]

@Ngwpower I use this one which is earlier in this thread, an it works with my domoticz.

MySprinkler for MySensors

Arduino Multi-Zone Sprinkler Control

May 31, 2015

*** Version 2.0

*** Upgraded to http://MySensors.org version 1.4.1
*** Expanded for up to 16 Valves
*** Setup for active low relay board or comment out #define ACTIVE_LOW to switch to active high
*** Switch to bitshift method vs byte arrays
*** Changed RUN_ALL_ZONES Vera device to 0 (was highest valve)
*** Added optional LCD display featuring remaining time, date last ran & current time
*** Features 'raindrop' and 'clock' icons which indicate sensor is updating valve data and clock respectively
*** Added single pushbutton menu to manually select which program to run (All Zones or a Single Zone)
*** Added option of naming your Zones programmatically or with Vera (V_VAR3 used to store names)

Utilizing your Vera home automation controller and the MySensors.org gateway you can
control up to a sixteen zone irrigation system with only three digital pins.  This sketch
will create NUMBER_OF_VALVES + 1 devices on your Vera controller

This sketch features the following:

* Allows you to cycle through All zones (RUN_ALL_ZONES) or individual zone (RUN_SINGLE_ZONE) control.
* Use the 0th controller to activate RUN_ALL_ZONES (each zone in numeric sequence 1 to n)
  using Variable1 as the "ON" time in minutes in each of the vera devices created.
* Use the individual zone controller to activate a single zone.  This feature uses
  Variable2 as the "ON" time for each individual device/zone.
* Connect according to pinout below and uses Shift Registers as to allow the MySensors
  standard radio configuration and still leave available digital pins
* Turning on any zone will stop the current process and begin that particular process.
* Turning off any zone will stop the current process and turn off all zones.
* To push your new time intervals for your zones, simply change the variable on your Vera and
  your arduino will call to Vera once a minute and update accordingly.  Variables will also be
  requested when the device is first powered on.
* Pushbutton activation to RUN_ALL_ZONES, RUN_SINGLE_ZONE or halt the current program
* LED status indicator

PARTS LIST:
Available from the MySensors store - http://www.mysensors.org/store/
* Relays (8 channel)
* Female Pin Header Connector Strip
* Prototype Universal Printed Circuit Boards (PCB)
* NRF24L01 Radio
* Arduino (I used a Pro Mini)
* FTDI USB to TTL Serial Adapter
* Capacitors (10uf and .1uf)
* 3.3v voltage regulator
* Resistors (270 & 10K)
* Female Dupont Cables
* 1602 LCD (with I2C Interface)
* LED
* Push button
* Shift Register (SN74HC595)
* 2 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 3 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 22-24 gauge wire or similar (I used Cat5/Cat6 cable)
* 18 gauge wire (for relay)
* Irrigation Power Supply (24-Volt/750 mA Transformer)


INSTRUCTIONS:

* A step-by-step setup video is available here: http://youtu.be/l4GPRTsuHkI
* After assembling your arduino, radio, decoupling capacitors, shift register(s), status LED, pushbutton LCD (I2C connected to
  A4 and A5) and relays, and load the sketch.
* Following the instructions at https://MySensors.org include the device to your MySensors Gateway.
* Verify that each new device has a Variable1, Variable2 and Variable3. Populate data accordingly with whole minutes for
  the RUN_ALL_ZONES routine (Variable1) and the RUN_SINGLE_ZONE routines (Variable 2).  The values entered for times may be zero and
  you may use the defaulet zone names by leaving Variable3 blank.
* Once you have entered values for each zone and each variable, save the settings by pressing the red save button on your Vera.
* Restart your arduino; verify the settings are loaded into your arduino with the serial monitor; the array will be printed
  on the serial monitor.
* Your arduino should slow-flash, indicating that it is in ready mode.
* There are multiple debug serial prints that can be monitored to assure that it is operating properly.
* ***THIS SHOULD NO LONGER BE NEEDED*** The standard MySensors library now works. https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours

Does anyone have a working portable Arduino IDE for that sketch that would want to share with me? I lost my installation and so many things changed in the built in scripts when you do a new installation. I can compile the project even using 1.4.5 mysensors libraries.
Thanks a lot.

[petewill]

@Ngwpower Don't give up! It is a learning curve for sure but totally worth it when you finally get it. Try the irrigation controller sketch from the MySensors 1.5 library example. All the required stuff should be there.

@Sergio-Rius I'm not sure what you're looking for. Do you need the 1.5 version?

[A Former User]

Thanks, I envy you young people at 67 just opening the wide world of tech - do't have to do this sitting on a motor grader or Bull Dozer in the high desert. I have tried from 1.3 to 2.0 and thought I saw a flicker of LED in the string of switches, as in your example. Had my 5V on the wrong pin, so back to square one.
I am having fun attempting to learn the terminology as well as the application!

[Lars65]

@Ngwpower I am 55 and still learning. I don't know anything about programming. But I spend a lot of time on forums, and reading.
I would love to learn programming, but I have a slow learning curve now.
I work as a processengineer,so I guess I can understand some logic.
But this is really fun stuff.
Started up a couple of years ago, reading about a home made CNC mill.
Now I have my own, and it got pretty big can mill surfaces about 1100x800mm.
And I use it most to mill PCB boards. Hahaha.

[Sergio Rius]

@petewill
The problem are the new libraries that come with newer arduino ide. My attempts fail about the wire.h library location or a wrong "positive" variable at liquiddisplay.
I think it's not compatible with newer libraries.

I was just thinking the other day I can't wait until I retire so I'll have more time to work on this stuff
I'm glad you're not giving up. It took me a while to get it too but eventually it all started to make a little sense. Unfortunately you're starting at a harder time because we are all still getting comfortable with 2.0

@Sergio-Rius Ok, I haven't updated my libraries for a while so hopefully these will work for you. 0_1468884836658_Libraries.zip

[Sergio Rius]

@petewill
Thank you very much. Unfortunately those are not the libraries I've problems with. The problem are the built-in ones. The ones that come with the Arduino IDE.
What version of the IDE are you running? I guess you use the Mysensors 1.4.2 libs.

I installed Arduino IDE 1.6.9 and using your libraries, those are the errors shown:

As you can appreciate, the Wire library is at the ../Wire path, so that error is meaningless.
I told you that I hate java environments? I still haven't found one that works out of the developer computer without issues. X)

EDIT: So the problem is that the Wire library has been updated, but we are still using an old version of the LiquidCrystal. This last one expects the .h files been on the root library folder but this has been changed in newer versions. Built-in libraries have their code in "src" subfolder.
I moved it to parent folder and it compiles, but I don't know what will happen with other dependencies.
Better would be updating the sketch.

[Sergio Rius]

@Lars65
As you also use it from Domoticz, your controller notices the changes in valves? I mean, when the IC is cycling through zones, Domoticz correctly changes states or you must refresh the page for it to show?

[Lars65]

@Sergio-Rius yes, I can turn them on/off, and the switch is also shifting from on/off.

[Lars65]

@Sergio-Rius Those can you download from internet. About Liquidcrystal is there a newer version called NewLiquidCrystal, that is also possible to download.
That one worked for me.
I deleted all my duplicates, it is anoying when you get those messeges in the arduino ide.
Also the fatal error you get is ../wire/wire.h.
seems like you have #include <../Wire/Wire.h
What happens if you just write #include Wire.h

What happens if you just

[Sergio Rius]

@Lars65
Thanks. No, I finally made it work.
I only have to find why my Domoticz don't update the switch status.

[AWI]

@Sergio-Rius you can change the reference in the display library files. Just remove the path to the wire.h library.

[A Former User]

@Lars65
Tried your sketch as well as a few of my own adjustments, still getting

At a loss of where I missed this in the library!
Rather be riding my scooter! got to get it done!

I'll try it.

@Ngwpower
Don't drop the towel. Just install the library from the libraries manager.

Am I looking in the wrong place?

I have installed the various library and it doesnt help. My IDE version is 1.6.10.

[Sergio Rius]

@PaweMed
If you've done a new installation, perhaps you installed Mysensors libraries from the IDE lib manager. In that case you could have installed v2.0.
In the newer version the library has changed to Mysensors.h, please read the documentation carefully as this is not a minor upgrade:

[dbemowsk]

I am in the process of building this controller and in reading the comments here where some were asking about a master valve and how to control it. This is the concept that I am going to try with my setup.

I only have 4 zones to control, so with the 8 channel relay board that I have, I am going to use channel 8 as my pump start relay control. The idea is that when any one channel is on, the diodes will activate the master valve, but keep the signal from back-feeding into another relay channel.

Hope that helps some people out there.

[dbemowsk]

So I figured I would share my progress with my version of this project. The majority of the build was done to the schematic from the build section of the site. The only changes I am making are eliminating the use of Q0 on the shift register, and wiring in diodes like I mentioned in my previous post to control my pump start relay using relay channel 8 when any zone is turned on. I may even add a connection for one more digital line for a pump only startup, but will have to see about the code mods to do that.

One of my hurdles that I wanted to overcome was what kind of case I would be building this in. I searched on ebay a bit, but couldn't find what I wanted. I was digging through some old stuff one day and found an old composite video A/V switcher that I no longer use.


Rather than recycling it, I figured, why not up-cycle it. The case was the perfect size for the 8 channel relay board. I even kept the back portion of the original circuit board to re-use the old DC in jack and build my regulator circuit on using an AMS1117 3.3v regulator. The output of the power board is Ground (black), +5V (red) and +3.3V (yellow).


I cut a slot in the front of the case to allow access to the relay connections.

The connections came out just enough to allow access to the screw terminals. You can also see the mouning of the LCD, push button and status LED.


I designed the circuit board so that it could plug directly on top of the 8 channel relay board. Notice the header connector strip between the pro mini and the shift register. There is just enough room above the blue 3 input power connector to attach the FTDI cable for programming the pro mini. The last thing I need to add to the board is the 8 diodes to control the pump start relay which will be channel 8 on the relay board. Currently the code uses outputs Q0 thru Q7 of the shift register to control relays 1 thru 8. I will need to make a slight change to the code to use Q1 thru Q7 as the first 7 relays as it was easier to connect it that way to the header connector. I am eliminating the use of Q0 in the circuit.

I am having a few issues with compiling the code to upload to the pro mini. It is telling me that it can't find the LiquidCrystal.h file, and I have the library in my arduino library folder. The folder has both the LiquidCrystal.h and LiquidCrystal_I2C.h files, so I am not sure what is up there. I hope to have it figured out soon so I can test the assembly.

Thanks for reviewing.

[dbemowsk]

I am trying to use this controller with Domoticz and I am wondering how to set the valve times. Is there anyone that is using this controller with Domoticz that can help?

[Huczas]

Hi, in original code is written to work with Vera - this is similar to Domoticz. But I same like you have Domoticz on my RPi0. Some time ago I changed some lines in this code that it is working now with Domoticz.

Utilizing your Vera home automation controller and the MySensors.org gateway you can
control up to a sixteen zone irrigation system with only three digital pins.  This sketch
will create NUMBER_OF_VALVES + 1 devices on your Vera controller

This sketch features the following:

* Allows you to cycle through All zones (RUN_ALL_ZONES) or individual zone (RUN_SINGLE_ZONE) control.
* Use the 0th controller to activate RUN_ALL_ZONES (each zone in numeric sequence 1 to n)
  using Variable1 as the "ON" time in minutes in each of the vera devices created.
* Use the individual zone controller to activate a single zone.  This feature uses
  Variable2 as the "ON" time for each individual device/zone.
* Connect according to pinout below and uses Shift Registers as to allow the MySensors
  standard radio configuration and still leave available digital pins
* Turning on any zone will stop the current process and begin that particular process.
* Turning off any zone will stop the current process and turn off all zones.
* To push your new time intervals for your zones, simply change the variable on your Vera and
  your arduino will call to Vera once a minute and update accordingly.  Variables will also be
  requested when the device is first powered on.
* Pushbutton activation to RUN_ALL_ZONES, RUN_SINGLE_ZONE or halt the current program
* LED status indicator

PARTS LIST:
Available from the MySensors store - http://www.mysensors.org/store/
* Relays (8 channel)
* Female Pin Header Connector Strip
* Prototype Universal Printed Circuit Boards (PCB)
* NRF24L01 Radio
* Arduino (I used a Pro Mini)
* FTDI USB to TTL Serial Adapter
* Capacitors (10uf and .1uf)
* 3.3v voltage regulator
* Resistors (270 & 10K)
* Female Dupont Cables
* 1602 LCD (with I2C Interface)
* LED
* Push button
* Shift Register (SN74HC595)
* 2 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 3 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 22-24 gauge wire or similar (I used Cat5/Cat6 cable)
* 18 gauge wire (for relay)
* Irrigation Power Supply (24-Volt/750 mA Transformer)


INSTRUCTIONS:

* A step-by-step setup video is available here: http://youtu.be/l4GPRTsuHkI
* After assembling your arduino, radio, decoupling capacitors, shift register(s), status LED, pushbutton LCD (I2C connected to
  A4 and A5) and relays, and load the sketch.
* Following the instructions at https://MySensors.org include the device to your MySensors Gateway.
* Verify that each new device has a Variable1, Variable2 and Variable3. Populate data accordingly with whole minutes for
  the RUN_ALL_ZONES routine (Variable1) and the RUN_SINGLE_ZONE routines (Variable 2).  The values entered for times may be zero and
  you may use the defaulet zone names by leaving Variable3 blank.
* Once you have entered values for each zone and each variable, save the settings by pressing the red save button on your Vera.
* Restart your arduino; verify the settings are loaded into your arduino with the serial monitor; the array will be printed
  on the serial monitor.
* Your arduino should slow-flash, indicating that it is in ready mode.
* There are multiple debug serial prints that can be monitored to assure that it is operating properly.
* ***THIS SHOULD NO LONGER BE NEEDED*** The standard MySensors library now works. https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours

Ok, originally time - how long relay is triggered was downloaded from Vera, I commented out this two lines and specify time there. When you power on arduino - program is trying to connect to Vera and download all data but it obviously fail at it. After a while it's just get date and time from Domoticz. So no names of zones or how long water them. All is hard coded in Arduino.

int variable1 = 15; // atoi(message.data);// RUN_ALL_ZONES time
int variable2 = 10; //atoi(message.data);// RUN_SINGLE_ZONE time

Now there is 15 minutes if you trigger all zones and 10 minutes if you choose specific single zone.

If you want change it you need burn it again on Arduino - so it is not the best solution, but it works And it is about 1 week with testing all with laptop and FTDI connected to this controller. After that - you can leave it forever.

PS, also I changed date and time - it is 24h and DD/MM/YY - so more European friendly

[dbemowsk]

@Huczas One of the main things I wanted with this project was the ability to change the watering times in the automation software using a script. If I have to reprogram the arduino every time I want to change a time it seems pointless . I am looking into a few ideas with this to make it work in Domoticz. If I come up with something, it is most likely going to be a hack workaround.

I have a post also in the Domoticz forum on a more generalized solution that would cover this situation. Seems though that this is something that the Domoticz team will need to implement. Hopefully I can figure out some kind of workaround to get this going for now.

[Huczas]

@dbemowsk Hmm if you set 1 hour or more and start watering in Domoticz, then you can manually (or by script) turn off wathering during that time - this is my simple solution to your problem

But remember - RPi isn't that reliable for me, it can freeze and then you get swamp instead of nice grass.

[dbemowsk]

@Huczas That is all the more reason to have it on the sprinkler controller node. I am trying what I think might be a workable solution. I need to do more testing with it tonight to see if it's going to work, but I think it will. Once I test it I will post my code.

[Sergio Rius]

@dbemowsk

While domoticz devs implement a way of better managing variables, perhaps you can implement a text sensor in the sketch and use it like a "times array". You could then populate it from Domoticz and send to the node as it was some text to show on a display.

I was porting this sketch to mysensors v2 but the changes on this version are so deep that I discarded it.

[dbemowsk]

@Sergio-Rius That is the exact thing I am working on. In Domoticz it shows up as devices, but I can live with that for now until they can do something.

[Mark Jefford]

domoticz i don't think have plans to support this, they took out the ability to use free text variables.

I plan on doing 1 minute cycles for irrigation and using a moisture sensor to evaluate how much longer the cycles need to run for.

[Sergio Rius]

@Mark-Jefford
DOH!

that's unfortunate. Do they have any other way to store and retrieve variables? Has anyone reached out to them with this need?

Can you elaborate a little more? What do you mean when you say free text variables?

[Sergio Rius]

Now that I read it twice... Just see that I writed "text sensor" not text or custom variables. That was what I first thought as a solution when I read about the the custom variable sending was dropped.

And yes, it's so unfortunate that Domoticz doesn't foresees the need to have "intelligent" nodes. That's so limiting. I would like to build, for example, a garage door opener or a central heating controller. Those things must continue working even if domoticz loses connection. And they must have standalone routines that must be preconfigured without being a programmer.
What if someone wants to sell an easy to use kit? In my language we say this is "andar con burreras", walking the path with those flaps horses and donkeys wear so they can't see sidewise.

[dbemowsk]

@Sergio-Rius said:

I agree. That's a big part of automation.

[dbemowsk]

I am very close to having this working. The hardest part so far is sorting out all the text devices in Domoticz. I needed to use JSON calls to set the data for each of the text devices, but once they are set I shouldn't have to change them. But being JSON calls I should be able to easily change them with a script if needed.

So I have the node present S_INFO devices for each of the 3 variables (all zones time, individual zone time, and zone name). I have 4 zones, so that presents 12 new devices to Domoticz. I have set zone names and they display correctly on the irrigation controller, I just need to figure out some of the zone time variables and what devices they are attached to.

I should have this working in the next couple days and once I get it I will post the code with some notes on configuring it all.

[PierreSt]

Just an idea I was considering for my project, but haven't got around implementing yet so I don't know how viable it is.
Wouldn't it be possible to use a S_Dimmer type of device instead of an S_Light?
That way you can set the "dimmer" value in the UI between 0-100, and use this as the minutes in the sketch (I doubt I will water any part of my garden more than 100 mn). Granted it does not allow to have 2 different settings for manual and automatic, but I don't see this as a real limitation (actually, S_Dimmer also has a V_Watt variable, so theoretically you could also use that one).

[dbemowsk]

So I think I have this figured out.One of the things that I had to contend with was running out of memory on my 5V Pro Mini 328. To fix this I had to comment out and shorten some of the DEBUG PRINTLN statements which didn't impede functionality.

The key to making this work is presenting 3 new sensors for each zone. The sensors are S_INFO sensors that use V_TEXT variables. Because these are new to 2.0 and our sketch is for 1.5, we need to define them to be able to use them.

const int V_TEXT = 47;
// new S_INFO sensor type (development 20150905)
const int S_INFO = 36 ;

Here is how I present the new sensors. The S_LIGHT sensor is the valve control. The next 3 S_INFO sensors are the replacements for V_VAR1 - V_VAR3. They are defined as follows;
All zones time
Individual zone time
Zone display name

 for (byte i = 0; i <= NUMBER_OF_VALVES; i++)
  {
    gw.present((i * 4), S_LIGHT);
    gw.present(((i * 4) + 1), S_INFO);
    gw.present(((i * 4) + 2), S_INFO);
    gw.present(((i * 4) + 3), S_INFO);
  }

The hardest part in this was figuring out the V_TEXT values on the Domoticz side. What I found was the easiest was to set each to a numeric value from 1 to whatever number of sensors are presented. To set the values type this into the address bar of your web browser:

http://{your_domoticz_ip_address}:8080/json.htm?type=command&param=udevice&idx=41&nvalue=0&svalue=1

Replace the 41 in idx=41 wit the idx value in the setup>devices list, and change the 1 in svalue=1 to the number next number. Once those are set, start all zones using the button on the controller. You will see one of the numbers on the display. Match that number with it's index (idx) value and re-run the above json command changing the idx to the matched index, and the svalue to the name of the zone:

http://{your_domoticz_ip_address}:8080/json.htm?type=command&param=udevice&idx=36&nvalue=0&svalue=Run all zones

Repeat this for all zone names. Then repeat the process by letting a zone start and matching a zone time to it's index. That is the reason for setting each V_TEXT variable to a unique number. When testing each zone on an "All Zones" run, it is best to find the first zone and set the time to 1 minute. Then run "All Zones" again and let the first zone run its 1 minute to hit the zone 2 time. Continue this through all zones changing the Domoticz names and values for each to identify them all.

I have not been able to fully test this as my controller is set up slightly different than the one presented. I have done the steps above and have all of that set, but my zone 1 is my master valve, and zones 2 through 5 are my zones 1 through 4. Because of this I need to figure out the changes in my sketch. If someone can test this as I have it so far, that would help. Once I know this works, I will make my needed changes.

Here is the complete modified sketch:

/*
MySprinkler for MySensors

Arduino Multi-Zone Sprinkler Control

May 31, 2015

*** Version 2.0

*** Upgraded to http://MySensors.org version 1.4.1
*** Expanded for up to 16 Valves
*** Setup for active low relay board or comment out #define ACTIVE_LOW to switch to active high
*** Switch to bitshift method vs byte arrays
*** Changed RUN_ALL_ZONES Vera device to 0 (was highest valve)
*** Added optional LCD display featuring remaining time, date last ran & current time
*** Features 'raindrop' and 'clock' icons which indicate sensor is updating valve data and clock respectively
*** Added single pushbutton menu to manually select which program to run (All Zones or a Single Zone)
*** Added option of naming your Zones programmatically or with Vera (V_VAR3 used to store names)

Utilizing your Vera home automation controller and the MySensors.org gateway you can
control up to a sixteen zone irrigation system with only three digital pins.  This sketch
will create NUMBER_OF_VALVES + 1 devices on your Vera controller

This sketch features the following:

* Allows you to cycle through All zones (RUN_ALL_ZONES) or individual zone (RUN_SINGLE_ZONE) control.
* Use the 0th controller to activate RUN_ALL_ZONES (each zone in numeric sequence 1 to n)
  using Variable1 as the "ON" time in minutes in each of the vera devices created.
* Use the individual zone controller to activate a single zone.  This feature uses
  Variable2 as the "ON" time for each individual device/zone.
* Connect according to pinout below and uses Shift Registers as to allow the MySensors
  standard radio configuration and still leave available digital pins
* Turning on any zone will stop the current process and begin that particular process.
* Turning off any zone will stop the current process and turn off all zones.
* To push your new time intervals for your zones, simply change the variable on your Vera and
  your arduino will call to Vera once a minute and update accordingly.  Variables will also be
  requested when the device is first powered on.
* Pushbutton activation to RUN_ALL_ZONES, RUN_SINGLE_ZONE or halt the current program
* LED status indicator

PARTS LIST:
Available from the MySensors store - http://www.mysensors.org/store/
* Relays (8 channel)
* Female Pin Header Connector Strip
* Prototype Universal Printed Circuit Boards (PCB)
* NRF24L01 Radio
* Arduino (I used a Pro Mini)
* FTDI USB to TTL Serial Adapter
* Capacitors (10uf and .1uf)
* 3.3v voltage regulator
* Resistors (270 & 10K)
* Female Dupont Cables
* 1602 LCD (with I2C Interface)
* LED
* Push button
* Shift Register (SN74HC595)
* 2 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 3 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 22-24 gauge wire or similar (I used Cat5/Cat6 cable)
* 18 gauge wire (for relay)
* Irrigation Power Supply (24-Volt/750 mA Transformer)


INSTRUCTIONS:

* A step-by-step setup video is available here: http://youtu.be/l4GPRTsuHkI
* After assembling your arduino, radio, decoupling capacitors, shift register(s), status LED, pushbutton LCD (I2C connected to
  A4 and A5) and relays, and load the sketch.
* Following the instructions at https://MySensors.org include the device to your MySensors Gateway.
* Verify that each new device has a Variable1, Variable2 and Variable3. Populate data accordingly with whole minutes for
  the RUN_ALL_ZONES routine (Variable1) and the RUN_SINGLE_ZONE routines (Variable 2).  The values entered for times may be zero and
  you may use the defaulet zone names by leaving Variable3 blank.
* Once you have entered values for each zone and each variable, save the settings by pressing the red save button on your Vera.
* Restart your arduino; verify the settings are loaded into your arduino with the serial monitor; the array will be printed
  on the serial monitor.
* Your arduino should slow-flash, indicating that it is in ready mode.
* There are multiple debug serial prints that can be monitored to assure that it is operating properly.
* ***THIS SHOULD NO LONGER BE NEEDED*** The standard MySensors library now works. https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours

Curious to see how this works for people.

[Sergio Rius]

@dbemowsk

Just a hint on memory: Why creating three sensors for each valve? Why not creating a unique sensor with array contents for all valves?

[dbemowsk]

@Sergio-Rius I hadn't thought of the array. I've never dealt with a S_INFO/V_TEXT as an array. Do you have an example of this? It does sound like an easier approach.

[AWI]

@dbemowsk I would suggest to take @PierreSt advice and go for a V_PERCENTAGE device. From my perspective you wil mostly deal with "a scale of fixed values' for more or less intensive irrigation. As you are working with Domoticz you can use a "Selector switch" to select the diiferent options.

I am currently using this for selecting patterns in my Wall mounted mood light and it works like a charm.

If anyone is intrested I will publish a "how-to" (in the Domoticz section)

[Sergio Rius]

@AWI
While that would be a logical approach, the the dimmer control in Domoticz it's complex and sometimes requires more than one click to activate. In other interfaces (Android, etc) that could be worse, and should change in the future.

@dbemowsk
I did not use S_INFO in my sketch, but I managed to use an array for valves configuration and may be pretty interesting if we mix the two of them.

Note that this is a version 2.0 sketch, and that I removed all the remote management stuff. Due to the flow change in v2, the display menu was so difficult to do.
Perhaps you can adapt it back and get back to the original idea.

As you may noticed, it can control up to 32 valves and you only have to populate the array. It'll be nice to request this data to domoticz and after a timer or received it, store in eeprom and populate the sub-nodes. Then in subsequent starts, boot with the info on eeprom and ask for changes.
The sensor shuts itself the "valves" and if time is set to zero runs them without limit.

That's not my irrigation controller, but my whole garden controller. (thaks the op for the idea)

[dbemowsk]

@Sergio-Rius Just a few things. I am assuming that the array you are talking about is "myElement". I am fairly new to MySensors and Domoticz. How do you use this array with Domoticz to send the zone times to the controller? It looks like you are setting the valve names and times within the sketch as if they are permanently set on the controller. I am a little confused about the presentation of the S_BINARY, Elm.Name:

        myElement Elm = myElements[i];
        present(i, S_BINARY, Elm.Name);

My understanding is that S_BINARY is just for on/off which I am guessing is the on/off control for the zone. What does the Elm.Name do though? Do yoy have a way to set valve times from within Domoticz?

I also noticed that you removed the time sync with the receiveTime() function. This tells me that you are not sending the current time to the controller. Any reason for this?

As for my sketch, I am thinking of another route to go with this where I can send the valve times and names using a single S_INFO sensor. I plan to use some of the information from this forum post: Splitting a string. The idea is to use a separator character such as ":" or "|" to create a pseudo array using a single string. Doing this will eliminate 2 S_INFO sensors for each zone, and also make it easier to configure. I am going to work on this tonight and see where I get with it.

[dbemowsk]

@AWI I am still not a big fan of the V_PERCENTAGE route. I like the flexibility of the all zones time as well as the individual zone times. I suppose from a scripting sense it wouldn't matter too much, but I still think it's easier and more flexible the other way.

[dbemowsk]

OK, so I've modified my sketch making the change to only use a single S_INFO sensor. The idea is to send a pipe delimited string of all the config data for a zone in the following format:
{all zone time}|{individual time}|{zone name}

45|60|Garden/pond 

So all zones call uses 45 minutes, individual zone time is 60 minutes, and the zone name is "Garden/pond"

Well without further adieu, here is the sketch.

MySprinkler for MySensors

Arduino Multi-Zone Sprinkler Control

May 31, 2015

*** Version 2.0

*** Upgraded to http://MySensors.org version 1.4.1
*** Expanded for up to 16 Valves
*** Setup for active low relay board or comment out #define ACTIVE_LOW to switch to active high
*** Switch to bitshift method vs byte arrays
*** Changed RUN_ALL_ZONES Vera device to 0 (was highest valve)
*** Added optional LCD display featuring remaining time, date last ran & current time
*** Features 'raindrop' and 'clock' icons which indicate sensor is updating valve data and clock respectively
*** Added single pushbutton menu to manually select which program to run (All Zones or a Single Zone)
*** Added option of naming your Zones programmatically or with Vera (V_VAR3 used to store names)

Utilizing your Vera home automation controller and the MySensors.org gateway you can
control up to a sixteen zone irrigation system with only three digital pins.  This sketch
will create NUMBER_OF_VALVES + 1 devices on your Vera controller

This sketch features the following:

* Allows you to cycle through All zones (RUN_ALL_ZONES) or individual zone (RUN_SINGLE_ZONE) control.
* Use the 0th controller to activate RUN_ALL_ZONES (each zone in numeric sequence 1 to n)
  using Variable1 as the "ON" time in minutes in each of the vera devices created.
* Use the individual zone controller to activate a single zone.  This feature uses
  Variable2 as the "ON" time for each individual device/zone.
* Connect according to pinout below and uses Shift Registers as to allow the MySensors
  standard radio configuration and still leave available digital pins
* Turning on any zone will stop the current process and begin that particular process.
* Turning off any zone will stop the current process and turn off all zones.
* To push your new time intervals for your zones, simply change the variable on your Vera and
  your arduino will call to Vera once a minute and update accordingly.  Variables will also be
  requested when the device is first powered on.
* Pushbutton activation to RUN_ALL_ZONES, RUN_SINGLE_ZONE or halt the current program
* LED status indicator

PARTS LIST:
Available from the MySensors store - http://www.mysensors.org/store/
* Relays (8 channel)
* Female Pin Header Connector Strip
* Prototype Universal Printed Circuit Boards (PCB)
* NRF24L01 Radio
* Arduino (I used a Pro Mini)
* FTDI USB to TTL Serial Adapter
* Capacitors (10uf and .1uf)
* 3.3v voltage regulator
* Resistors (270 & 10K)
* Female Dupont Cables
* 1602 LCD (with I2C Interface)
* LED
* Push button
* Shift Register (SN74HC595)
* 2 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 3 Pole 5mm Pitch PCB Mount Screw Terminal Block
* 22-24 gauge wire or similar (I used Cat5/Cat6 cable)
* 18 gauge wire (for relay)
* Irrigation Power Supply (24-Volt/750 mA Transformer)


INSTRUCTIONS:

* A step-by-step setup video is available here: http://youtu.be/l4GPRTsuHkI
* After assembling your arduino, radio, decoupling capacitors, shift register(s), status LED, pushbutton LCD (I2C connected to
  A4 and A5) and relays, and load the sketch.
* Following the instructions at https://MySensors.org include the device to your MySensors Gateway.
* Verify that each new device has a Variable1, Variable2 and Variable3. Populate data accordingly with whole minutes for
  the RUN_ALL_ZONES routine (Variable1) and the RUN_SINGLE_ZONE routines (Variable 2).  The values entered for times may be zero and
  you may use the defaulet zone names by leaving Variable3 blank.
* Once you have entered values for each zone and each variable, save the settings by pressing the red save button on your Vera.
* Restart your arduino; verify the settings are loaded into your arduino with the serial monitor; the array will be printed
  on the serial monitor.
* Your arduino should slow-flash, indicating that it is in ready mode.
* There are multiple debug serial prints that can be monitored to assure that it is operating properly.
* ***THIS SHOULD NO LONGER BE NEEDED*** The standard MySensors library now works. https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours

the dimmer control in Domoticz it's complex and sometimes requires more than one click to activate

Can you elaborate on this? In my setup the Dimmer is as reliable as any other control. Main limitation is that the standard dimmer can only assume 16 "states"/ values.

@dbemowsk said:

I am still not a big fan of the V_PERCENTAGE route

While introducing the V_TEXT/S_INFO type we were aware that this would be a would open up the route to many "non standard" applications. I personally try to keep everything in the standard types or to have a standard defined for it. (like in the V_ORIENTATION suggestion in the Orientation actuator ).
Sometimes the choice is limited as with the V_PERCENTAGE/ DIMMER implementation in Domoticz as there is no "generic" type to represent just a value (int/float) or date/time (y/m/d hs).

@dbemowsk said:

How do you use this array with Domoticz to send the zone times to the controller? It looks like you are setting the valve names and times within the sketch as if they are permanently set on the controller.

Yes, that was the part where we supposedly had to join our sketches. Just getting all the array contents from an S_INFO. Perhaps using some Json to array conversion. Should be some library for conversions there.

I am a little confused about the presentation of the S_BINARY, Elm.Name:

        myElement Elm = myElements[i];
        present(i, S_BINARY, Elm.Name);

My understanding is that S_BINARY is just for on/off which I am guessing is the on/off control for the zone. What does the Elm.Name do though?

Elm.Name assigns a name to the valve. And presents to Domoticz. Still doesn't exists a way to get from domoticz.

Do yoy have a way to set valve times from within Domoticz?

Again, still doesn't....

I also noticed that you removed the time sync with the receiveTime() function. This tells me that you are not sending the current time to the controller. Any reason for this?

Yes. as I said it was so complicated for me to integrate the "stand-alone functions" that use loop cycles for running the menu. I planned to make dedicated functions for it, but didn't have time.

As for my sketch, I am thinking of another route to go with this where I can send the valve times and names using a single S_INFO sensor. I plan to use some of the information from this forum post: Splitting a string. The idea is to use a separator character such as ":" or "|" to create a pseudo array using a single string. Doing this will eliminate 2 S_INFO sensors for each zone, and also make it easier to configure. I am going to work on this tonight and see where I get with it.

And why not using this approach on a single S_INFO, that could feed the array I have in my sketch?

Can you elaborate on this? In my setup the Dimmer is as reliable as any other control. Main limitation is that the standard dimmer can only assume 16 "states"/ values.

The dimmer is reliable. I was talking of interface widget being complex. In Domoticz, to activate one zone you would have to first click, and when the popup appears, click again on the blue (sphere?) for it to start.
In Imperihome, you would have up to 32 rgb dial indicators on your page and still don't get the current set value, and when you set it on, most of times it doesn't respect the current intensity value.

And that doesn't solve the double timing setup nor the naming.
I always like to apply the KISS rule to my developments and avoid to depend on other systems. Specially if they don't walk in the same direction. Imagine that in the future the dimmer system changes, for example, into a hue pallete.

And it's true that mysensors and domoticz is lacking a sensors configuration system.

[AWI]

@Sergio-Rius Think I understand and keep my systems as autonomous and simple as possible.
The route with S_INFO/V_TEXT won't bring you any luck, regarding the customization to be done in Domoticz to get values in V_TEXT (LUA / JSON).
btw. Like your sketch

[Sergio Rius]

@AWI
You'r right, that's not the best route. But until we have sensors configuration routines...
Will we have?

[AWI]

@Sergio-Rius Don't expect too much in either MySensors/ Domoticz unless you know of a "industry standard" approach which can be implemented with reasonable efforts by the community..

Are you saying that Domoticz primary focus is to follow existing industry standards? Some times you need to shift away from the standards. Giving users more options will only increase the software's user base. If it were me, I'd rather become the standard than chase it.

The main part of my new approach is this bit here:

      if (message.type == V_TEXT)
      {
        String valveMessage = String(message.data);
        char* valveData = &valveMessage[0]; //.c_str();
        DEBUG_PRINT(F("Recieved valve data:"));
        DEBUG_PRINT(i);
        DEBUG_PRINT(F(" = "));
        DEBUG_PRINTLN(valveMessage);

        char* var = strtok(valveData, "|");

        int variable1 = atoi(var); // RUN_ALL_ZONES time
        
        if (variable1 != allZoneTime[i])
        {
          allZoneTime[i] = variable1;

          zoneTimeUpdate = true;
        }
        
        var = strtok(NULL, "|");
        
        int variable2 = atoi(var);// RUN_SINGLE_ZONE time
        
        if (variable2 != valveSoloTime[i])
        {
          valveSoloTime[i] = variable2;

          zoneTimeUpdate = true;
        }
        
        var = strtok(NULL, "|");
        
        String newMessage = String(var);
        if (newMessage.length() == 0) 
        {
          DEBUG_PRINT(F("No Name for "));
          DEBUG_PRINTLN(i);
          break;
        }
        if (newMessage.length() > 16)
        {
          newMessage.substring(0, 16);
        }
        valveNickName[i] = "";
        valveNickName[i] += newMessage;
        DEBUG_PRINT(F("Recieved name "));
        DEBUG_PRINT(i);
        DEBUG_PRINT(F(" called: "));
        DEBUG_PRINTLN(valveNickName[i]);
      }
      receivedInitialValue = true;
    }
  }

The key is using strtok() to split the incoming string into it's parts. The code that I posted from my tests seems to work, at least from what I have tested so far. It uses one S_INFO sensor for each zone to carry the 3 parts that would be the V_VAR1 - V_VAR3 info in the original sketch. Granted it is only for 1.5, but if you can use anything from my 1.5 sketch in your 2.0 sketch, feel free.

Hi first Great projekt. All the things is Just ordred from eBay. But i Wonder what the yellow component is.

And mayby a tuturial have to make a complete HA kontroller. And have to set i Up. Rigtig now i have a raspberry pi with calaos. But i Dont know have to the it Up with the system.

Hope there is some help in here

@BulldogLowell

I love your programming skills, it is superb. Haven gone through your video, l was happy and l needed a modification to your setup. I want to use the arduino to power my irrigation with the following function.

Arduino with soil moisture sensor check. once the soil is dry, arduino to switch on the electric 1horse power pumping machine and at the same time open the solenoid valve to irrigate at a specified timing.

As per powering the pumping machine, arduino should check if there is public electricity supply before switching on the pump and if there is no public power supply then it should switch on the power generating set to power the pumping machine and solenoid valve.

After the sensor has confirmed that the soil is wet and moist, then arduino stops the pumping machine and then closes the electric 220v solenoid valve.

Second task.

Overhead Mist Sprayer (uses a different AC 1horse power pump)

A sensor to check when the sun temperature is 35 or 40 degrees or any programmed temperature and switch on the pumping machine to power the sprayer for a specified timing. Also arduino should should check if there is public electricity supply before switching on the pump and if there is no public power supply then it should switch on the power generating set to power the pumping machine.

Also irrigation records of time and dates and other function will be added up in the setup.

I like to know the hardwares l will need for this project, a guide and codes. I appreciate this .

Thanks

[BulldogLowell]

@wasam

There are several examples out there (either here or in the Arduino forum) of how to combine sketches for added functionality. Fortunately, you are starting with my code that is already non-blocking and uses little in the way of system resources so it should be straightforward from here.

The community here (including me) can assist in giving you what you want.

first thing is the hardware... assuming your using metric means you are 220VAC... you need a person familiar with mains switching to help you out there!

Where are you seeing the yellow component? Maybe it's the LED? Can you post a picture?

[impertus]

@petewill this One.

[petewill]

@impertus Ah, ok. That is a .1uf capacitor.

[BulldogLowell]

@petewill

which can be easily substituted by a flux capacitor.

[impertus]

@BulldogLowell Thx

Is this the rigth setup.

Irrigationcontroller <-----> Radio + ethernet (Gateaway) ------> Router + Wifi ------> RaspB with (Calaos HA controller)

Wifi -----> Calaos Mobile app

How does the HA controller detects the signal from the irrigation controller? some mystisk setup or plug an play..

What HA will you use (Opensouce)(With mobil function)

[petewill]

@BulldogLowell Ha! Unfortunately I'm fresh out of those...

@impertus Both @BulldogLowell and I use Vera as our home automation controller (not open source). My setup looks like: Irrigation Controller <> Ethernet Gateway <> Vera <> Vera Mobile App (usually AutHomationHD). I haven't tested any other controllers with this device but reading up a little in this forum post it appears that some people have got it to work with Domoticz.

[impertus]

@petewill yeahh i did a little bit of surfing on the forum. And felt over Domoticz. I see that also can run on RaspBerryPi. So think i will give that at try. It will be nice with a newbie guide how to setup my sensors to Domo. step by step..

now im waiting for the mailman with all my components

[Huczas]

Hi, I've done recently this setup - it works greate with domoticz and Raspberry Pi 0.
After some tests I findout that when I plug in power - sometimes all, sometimes 3 or 4 relays are turning ON for 1second.
If that happend my 24V power adapter will be in trash. How to prevent that? Do I need to add something in code (I'm not a programmer)?

[BulldogLowell]

@Huczas

try adding a delay in various places in setup() start with 5 or even 10 seconds.

[Huczas]

ok, I just get back from Hackerspace. Some people fix this issue:
SN74HC595 - 13 pin (OE from datascheet) - remove GND and then add pull up 1k resistor and wire it to Arduino pin 6

and software, added three lines in code:

  const int outputEnablePin = 6;

  pinMode(outputEnablePin, OUTPUT);
  digitalWrite (outputEnablePin, LOW);

put them after 190 line https://github.com/mysensors/MySensorsArduinoExamples/blob/master/examples/IrrigationController/IrrigationController.ino

should be like that:

<some code>
 //Setup Shift Register...
const int latchPin = 8;
const int clockPin = 4;
const int dataPin  = 7;
const int outputEnablePin = 6;
//
byte clock[8] = {0x0, 0xe, 0x15, 0x17, 0x11, 0xe, 0x0}; // fetching time indicator
byte raindrop[8] = {0x4, 0x4, 0xA, 0xA, 0x11, 0xE, 0x0,}; // fetching Valve Data indicator
// Set the pins on the I2C chip used for LCD connections:
//                    addr, en,rw,rs,d4,d5,d6,d7,bl,blpol
LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);  // Set the LCD I2C address to 0x27
MySensor gw;
//
MyMessage msg1valve(CHILD_ID_SPRINKLER, V_LIGHT);
MyMessage var1valve(CHILD_ID_SPRINKLER, V_VAR1);
MyMessage var2valve(CHILD_ID_SPRINKLER, V_VAR2);
//
void setup()
{
  SERIAL_START(115200);
  DEBUG_PRINTLN(F("Initialising..."));
  pinMode(latchPin, OUTPUT);
  pinMode(clockPin, OUTPUT);
  pinMode(dataPin, OUTPUT);
  pinMode(ledPin, OUTPUT);
  pinMode(waterButtonPin, INPUT_PULLUP);
  //pinMode(waterButtonPin, INPUT);
  attachInterrupt(1, PushButton, RISING); //May need to change for your Arduino model
  digitalWrite (ledPin, HIGH);
  DEBUG_PRINTLN(F("Turning All Valves Off..."));
  updateRelays(ALL_VALVES_OFF);
  pinMode(outputEnablePin, OUTPUT);
  digitalWrite (outputEnablePin, LOW);
<some code>

If somebody can update this project in github and that fritzling draw - would be super nice.

[petewill]

@Huczas Great, thanks! Have you tested these updates? Also, can you post a link the info on hackerspace?

[Huczas]

@petewill
Yes, I've tested this and it's working well!
Link to the hackerspace - HackerSpace Warsaw, they are on irc - where I talk with them, #hackerspace-pl at freenode servers.

[petewill]

@Huczas Oh, ok. I thought it was a forum post. Thanks for the update. I will work to get this updated.

[petewill]

@Huczas the code has been updated in the 2.0 GitHub branch. The wiring diagram has also been updated. Thanks for the fix!

[Huczas]

@petewill as I sad before - pull up 1k resistor and wire it to Arduino pin 6 - I mean

pull up - connect to power,
so should be 1k resistor connected with power source(that make sence with pull up) and also with pin 6. Like below:

[petewill]

@Huczas Ah, missed that. I fixed it.

[bsivley]

I just finished building this but when I go to upload the code to my arduino i get this error

'byte clock [8]' redeclared as different kind of symbol

what does this mean ?

thanks

[petewill]

@bsivley Are you using the libraries from the MySensors github page (https://github.com/mysensors/MySensorsArduinoExamples/tree/master/libraries)? I just compiled it without any errors. What version of the Arduino IDE are you using? What version of MySensors are you using?

[Andrej_AB]

@petewill Hi, Please can you advise what version Arduino IDE you are using for this sketch?

[rechin304]

This post is deleted!

[Andrej_AB]

Hi, Maybe somebody can help me with this issue? Managed to upload code for irrigation controller with Arduino IDE 1.6.12 but can't pair with Vera controller.

[petewill]

@Andrej_AB I'm using 1.6.12 but I haven't changed my node to 2.0 yet.
What is the issue you are having with pairing? Do you see the presentation messages on your gateway? Do you have other nodes successfully paired with your Vera?
