@BulldogLowell
OK, I will post the video. If I will manage I will also post serial output

@treb0r @BulldogLowel I had a chance to play a little bit with VAR1 this weekend. I verified that if you declare MyMessage var(CHILD_ID, V_VAR1); you can set it with gw.send(var.set("hello")); and request its value from the gateway using gw.request(CHILD_ID, V_VAR1);. you will get the answer in the incoming message handler under the V_VAR1 message

   if (message.type==V_VAR1) {
   	 Serial.println("got var1 answer");
   	 Serial.println(message.getString());
   }

However I still didn't manage to find how to access or show these values on the domoticz. their site crashed so couldn't ask this in the forum

[epierre]

@Moshe-Livne Domoticz (as of today) doesn't support V_VARx ...

[Moshe Livne]

@epierre it does but in a strange way. The vars are not display vars. They are stored in the db and can be fetched and set only by the sensor. Tried it, it works....

[epierre]

@Moshe-Livne this is not what @GizMoCuz said in a post... strange...

[Moshe Livne]

@epierre can you please link to the post?

[epierre]

here it is:

[Moshe Livne]

@epierre He meant in the sense that it does not display or use it for anything. he said there "it is used to store/retrieve variables". The thread was about the option to show the vars as part of the sensor output. for storing and retrieving, it works.... verified.... I might get annoyed enough to add to the code that the lua script can also retrieve these vars and then it would be sweet.....

[epierre]

ok good although it was not explicit... now I'll have to go back to him about water meter that heavily use V_VARs but is recognized.... as a power meter...

Hello
And thx for a nice forum, I did build the irrigation controller and tried to connect it to Domoticz. Everything just seems fine, LCD works, push button works and I can turn on the irrigation from Domoticz and it shows in the LCD.

But the problem is that it doesn't switch the relays on, it just says "no valve time" and then go watering cycle complete.

Any suggestions on what the problem might be...... Domoticz?

Regards

[BulldogLowell]

@moffen666

I don't have Domoticz but I suspect that the callback isn't functioning.

try populating the array with the desired times for each sequence. replace this:

int allZoneTime [NUMBER_OF_VALVES + 1];
int valveSoloTime [NUMBER_OF_VALVES + 1];

with something like this:

int allZoneTime [NUMBER_OF_VALVES + 1] = {0, 10, 10, 10, 5,<... how many valves you have with zero in the first position>} ;
int valveSoloTime [NUMBER_OF_VALVES + 1] = {0, 5, 5, 5, 5,<... how many valves you have with zero in the first position>};

This will load in the times that the program uses as your 'default' values. Then, you can check with Domoticz experts on getting the V_VAR variables working.

[moffen666]

Thx Bulldog
I will check asap and get back with the result.

Hi
I tried the code but it didn't compile, and I'm not good enough to be sure whats wrong.

I did try change the code and I did get it to compile, but I don't know if I got it right. You can see the lame attempt below the colored line.

[BulldogLowell]

@moffen666

Clearly you understand that you are to put the times for each of the valve zones, led by a zero into the array, and not copy my verbatim instructions...

How many valves do you have? You need that many (plus one) integer numbers separated by commas...

Example 8 valves:

...= {0,5,5,5,5,5,5,5,5};

You've commented out the wrong lines.

[moffen666]

Thx for the quick answer

I use 4 valves atm, I tried your suggestion but it seems it wont work for me.

Regards

[moffen666]

The inserted values in the array works from start, but it looks like the irrigation controller immediately starts to request valve data from the controller for variable1 and 2. As we cant set variable1 and 2 in Domoticz I guess it returns 0 and overwrite the inserted values in the arrays...or is it anything else happening?

  }*/

and this in loop():

//goGetValveTimes();

That will disable those callbacks and you should be OK with a HardCoded time table for the valves and valve names.

Thx Bulldog for all the help, everything seems to be working as it should now.

Keep up the good work :+1:

Updated code for 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

Hey Everyone,

I just made a follow up video to this irrigation controller that shows my logic I'm using to save water. It's pretty specific to my environment but hopefully you can use some of the ideas to save water in your environment. I have attached the logic I used in my PLEG device.

Hello,

looking at the project, I'm wondering why you propose 3.3V only, is this for the shift register and the screen ? Why not stay in 5V ?
