    What Arduino are you using?

    I cannot recall, but think I probably used a nano.

    @BulldogLowell I'm getting an error when I try to compile the code (I am finally getting to the point of uploading it). There are a long string of errors but they seem to be related to this:

        IrrigationController.ino:122:34: error: invalid conversion from 'int' to 't_backlighPol' [-fpermissive]
    
        In file included from IrrigationController.ino:59:0:
    
        C:\Users\petewill\Documents\Arduino\libraries\LiquidCrystal/LiquidCrystal_I2C.h:53:4: error:   initializing argument 3 of 'LiquidCrystal_I2C::LiquidCrystal_I2C(uint8_t, uint8_t, t_backlighPol)' [-fpermissive]
    
        LiquidCrystal_I2C (uint8_t lcd_Addr, uint8_t backlighPin, t_backlighPol pol);
    

    Here is the Arduino code:

    LiquidCrystal_I2C lcd(0x27, 16, 2);  // set the LCD I2C address to 0x27 (16 characters and 2 line display)
    

    I downloaded the 1.2.1 library from here: https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads

    Is there something else I should be doing?

    Thanks,

    Pete

    9:15am here in china!

    can you post what you are trying to compile? it looks like a library issue (as you figured out) but I want to make suer I can compile exactly what you have.

    @BulldogLowell 9am nice! I'm ready for bed 🙂

    Here is the code I'm trying to compile. I think it's pretty much what you have except a couple small additions like Child ID, Sketch Name etc.

    MySprinkler for MySensors
    
    Arduino Multi-Zone Sprinkler Control
    
    November, 2014
    
    *** 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 times and clock respectively
    
    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.
    * Pushbutton activation to RUN_ALL_ZONES
    * LED status indicator
    
    INSTRUCTIONS:
    
    * 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 and Variable2. Populate data accordingly with whole minutes for 
    the RUN_ALL_ZONES routine and the RUN_SINGLE_ZONE routines.  The values entered may be zero.  
    * 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.
    * https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours

    meanwhile I tried to compile my old code with the latest Arduino IDE and get the same errors...

    It may take me some time, but meanwhile you can try Arduino board for I2C library for LCDs.

    sorry!

    Good to know. I have around 80 MySensors devices so I'm always thinking about keeping communication to a minimum. I may just run it as is and if I notice any issues I can look into adjusting the code.

    Holy cow, ~80 MySensor devices.. I'm surprised Vera handles all that traffic reliably... My Vera3 can't seem to handle my ~35 Z-Wave and ~ 15 MySensors devices reliably...

    I'm in the starting process of moving everything over to HomeSeer. I'm really hoping this solution works better.. The little I've done so far, I'm VERY impressed. I will not miss PLEG (It's a great plug-in but difficult to build and maintain for me), as the built in event system in HS3 Pro is amazing and I've only just scratch the surface...

    Depends on your definition of reliably 🙂 I'd say 98% of the time there are no issues but the other 2% can be annoying... I am continually amazed by how well MySensors works. I just keep adding devices and it keeps performing. Henrik and team are awesome!

    Vera can definitely be frustrating. The key for me is to limit the plugins. I am very careful what I install. I'm sure I'll have to switch from Vera one day (unless they start making more powerful hardware) but for now it works and it's cheap. What are you going to do with MySensors when you switch? I love MySensors too much!!

    Jim,

    I did some searching and modified the code a little. It will now compile but I haven't had time to figure out what the purpose of lcd.write(0) was for. I have to go to work so I won't be able to look into it until later. Here are the items of code I changed to get it to compile:

    //LiquidCrystal_I2C lcd(0x27, 16, 2);  // set the LCD I2C address to 0x27 
    LiquidCrystal_I2C lcd(0x27);  // set the LCD I2C address to 0x27
    
     //*Added
     lcd.begin(16, 2); //(16 characters and 2 line display)
    //*Removed 
    // lcd.init();
    
    //*Removed 3 instances of:
    // lcd.write(0);
    

    Interestingly lcd.write(1); will compile. I also don't have an LCD to test with so I don't know if it will work.


  • Hero Member

    @petewill There is a MySensors plug-in for HS3, At the moment it is a bit limited, and has some bugs but the developer is working on it.


  • Admin

    @ServiceXp Good to know. I'll keep that in mind. Thanks for passing that on!

    @petewill

    lcd.write(0)

    Prints the '0' special character.

    There is a raindrop icon, which tells you times are downloading and a clock icon which designates clock updates.

    uint8_t clock[8] = {0x0,0xe,0x15,0x17,0x11,0xe,0x0}; // fetching time indicator
    uint8_t raindrop[8] = {0x4,0x4,0xA,0xA,0x11,0xE,0x0,}; // fetching Valve Data indicator
    

    convert the hex to binary you can see the shape (5 X 7 pixels, so disregard the first three bits):

    00000000
    00001110
    00010101
    00010111
    00010001
    00001110
    00000000
    

    can you see the clock face at 3:00?

    00000100
    00000100
    00001010
    00001010
    00010001
    00010001
    00001110
    00000000
    

    Can you see the raindrop?

    they are created here:

     lcd.createChar(0, clock);
     lcd.createChar(1, raindrop);
    

    if you look at the video above, they appear from time to time.

    cool right?

    Ok, good to know. I'll see if I can do a little searching on that. Maybe there is a different way to implement them now?? It will be hard to test without an LCD but hopefully it will come soon and I can post back 🙂

    Speaking of testing I was able to control my relays last night from Vera! SO COOL!! This is one of the devices I have been wanting to add for a long time. I can't wait to be able to turn on my valves from my phone when I'm turning on my sprinkler system. It sure will beat sprinting to/from the basement...

    Thanks again for the awesome work!

    Ok, thanks. I did a little research and found this from the Arduino website:

    When referencing custom character "0", if it is not in a variable, you need to cast it as a byte, otherwise the compiler throws an error. See the example below.

    http://www.arduino.cc/en/Reference/LiquidCrystalCreateChar

    I changed the code to this:

    byte clock[8] = {0x0,0xe,0x15,0x17,0x11,0xe,0x0};
    

    and this

    lcd.write(byte(0));
    

    and now it's compiling. But, I don't know if it's working.

    I'm still working on a couple of other small things I found. I'll post the code when I get it to a point where it's ready for your review.


  • Admin

    @BulldogLowell

    Here is the code with some changes. I have also attached a document with the changes highlighted. The most notable thing is I added some code to update the valve times when the device is first powered on. I hope that's ok.

    One thing I can't figure out, but hopefully you can, is the button is always acting like it's "pressed" when the Arduino is first powered on. This could be a problem as the power seems to go off in my house a couple of times a year (I don't want my irrigation to run when it's not supposed to). Any idea how to fix it? I've tried everything I could think of (which isn't much) and nothing worked.

    Anyway, here is the PDF with the changes Irrigation Controller Changes.pdf

    And the code:

    /*
    MySprinkler for MySensors
    
    Arduino Multi-Zone Sprinkler Control
    
    November, 2014
    
    *** 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 times and clock respectively
    
    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.
    * Pushbutton activation to RUN_ALL_ZONES
    * LED status indicator
    
    INSTRUCTIONS:
    
    * 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 and Variable2. Populate data accordingly with whole minutes for 
    the RUN_ALL_ZONES routine and the RUN_SINGLE_ZONE routines.  The values entered may be zero.  
    * 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.
    * https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads for the I2C library, or use yours

    One thing I can't figure out, but hopefully you can, is the button is always acting like it's "pressed" when the Arduino is first powered on. This could be a problem as the power seems to go off in my house a couple of times a year (I don't want my irrigation to run when it's not supposed to).

    You could try a bigger pullup resistor, maybe the pin floats for a brief moment or it is somehow energized... I've read about others having a problem like that. Alternatively, reverse the logic and pull pull the pin down to ground. I'd expect that one or both can correct that issue.

    Glad to have the improvements in the code, that's great! Always better to have another set of eyes on a project.

    Ok, I'll do some testing with that. I don't think I'll get the chance today but I should be able to do some tomorrow. It works perfectly after the first start up so hopefully a bigger resistor will help.


  • Contest Winner

    @petewill

    yeah, I see in the code that the pushbutton is using interrupt pin, but still needs to be set to input

    pinMode(PushButton, INPUT_PULLUP);
    

    start there, sorry!


  • Admin

    @BulldogLowell said:

    yeah, I see in the code that the pushbutton is using interrupt pin, but still needs to be set to input

    I thought I added it already with this:

    pinMode(waterButtonPin, INPUT_PULLUP);
    
    

    Is that correct? Maybe that's my problem...


  • Admin

    @BulldogLowell said:

    were you not getting a compile error? on the PushButton variable being undeclared?

    Ok, I still think I have some things to learn about interrupts. I thought PushButton was the method being called when the interrupt was triggered. I didn't think it was the pin. I thought the pin was the first item 1 in this case. But, I thought 1 isn't even the pin. It's the interrupt number which is pin 3 in the case of a Pro Mini. I also thought I needed to declare the pinMode even if it's already in the interrupt. So confusing... Am I totally off?


  • Contest Winner

    @petewill

    post deleted, my bad! your understanding is 100% correct!

    your PushButton is the ISR, so you are right

    Try the extra pullup or pull-down

    really sorry for confusing you! I'm mega jet lagged


  • Admin

    @BulldogLowell said:

    I'm mega jet lagged

    Totally understandable 🙂

    Ok, I'll try the other options discussed above and post back. Thanks.

    Try the extra pullup

    Well, I had almost no time to work on MySensors stuff this weekend. 😞 I did do a quick test last night and it seems the external pullup worked! I power cycled the node 3 times and each time it worked flawlessly. I'll continue to test but so far so good. Thank you!

    @petewill

    glad to hear that worked!

    @BulldogLowell Thanks for posting this. A sprinkler controller to replace my Rainbird controller is next on my list of projects.

    For those looking for a good and relatively cheap soil moisture sensor, these ones are pretty good and use a capacitive sensor: http://www.ebay.com/itm/261675851824. They transmit on 433 MHz. I currently use them with RFXCom and HomeSeer, but for those that don't have RFXCom, the protocol should be relatively easy to reverse engineer and then use directly with MySensors and a 433MHz receiver. I've also bought a few from here: https://www.plantcaretools.com/en/webshop/wireless-moisture-sensor-en-detail. Both sellers were good to deal with. The only drawback to them is that the antenna (and therefore range) is not very good, but there is an easy mod to improve that: http://www.domoticz.com/forum/viewtopic.php?f=13&t=2712

    Cheers

    Great Work Guys!!



  • @Sparkman I like the sensors, I just built some and was dbating the way to make smaller, what kind of battery life do those moisture sensors have?

    @petewill Time to change my current 16 valve arduino sprinklers to a little smarter version like yours! I love this community.
    You have been coming on with some awesome videos and contributions!


  • Admin

    @DrJeff I agree this is a great community! So much fun!

    Thanks for the kind words! All credit for this project goes to @BulldogLowell though. I just made the video 🙂



  • @BulldogLowell Sorry For not giving the credit where it is due! Major Props @BulldogLowell !

    They've been running for about 9 months on the first set of batteries (2xAAA) so far and are still going strong.

    I just made an irrigation controller... @petewill made it for everyone!

    just for inspiration, here's another irrigation controller video (no, it's not mine.. but one of my friends that made it)

  • Wow 48 channels thats awesome

    @tbowmo WOW! What did he use that for??



  • @tbowmo Time for a Shower, Can you say body sprays! 🙂


  • Admin

    @petewill

    He recently planted a lot of trees, so instead of walking around and watering each one manually he made this

    Its a arduino with a nrf24 module, but not using the mysensors library (yet...)

    here is a stab at modification for no shift register... not much changes.

    Not tested but it compiles...

    Let me know if you see anything in testing.

    /*
    MySprinkler for MySensors
    
    Arduino Multi-Zone Sprinkler Control
    
    June 30, 2015
    
    *** Version 2.0nsr //MODIFIED FOR NO SHIFT REGISTER
    
    *** 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

  • thank you for this modification. I will test it today. Shall it be working withou any problems with Domoticz on Raspberry Pi?

    I assume so. It is using S_LIGHT, one of the most used device types. I am unsure however if Domoticz supports V_VAR1 & V_VAR2 for that device type, so you may have to check with other forum members who use Domoticz.


  • Hero Member

    Do you think I I could use that kind of design in parallel of a static watering controller, so I could have the basic program with the controller, and manage extras with the arduino/mysensors ?

    Inspired by @BulldogLowell's controller, I've been working on a MySensors irrigation controller that works in parallel with my RainBird Controller. I'm using a double set of relays (one 5VDC set that's controlled by the Arduino and a 24VAC set that's controlled by the 5VDC relays and the RainBird). This way I can also sense in my HA system when the valves have been opened by the RainBird controller. I have the base functionality finished and working on some additional bells and whistles. Will post some details in a separate thread later today.

    Cheers
    Al



  • Regarding the Video presenting this irrigation project: is the 15 min time, which is counting down after starting the valve via pressing the button, programed somewhere in the arduino code? Or it is taken from timer set in the Vera (or Domoticz) controller?

    Well, it is not working. Domoticz finds 5 switches, but on LCD there is Message: Failed Clock Synchronisation, and the Updating Valves but still 0 😕 Is the problems with V_VAR1 & V_VAR2 variables?

    On my Vera controller (as demonstrated by @petewill ) you would edit the times under Variable1 and Variable2, which corresponds to V_VAR1 and V_VAR2 in the program.

    The video shows how to modify the values in the arduino by changing the values. I am not sure if Domoticz supports such dataflow. Does Domoticz support V_VAR1 and V_VAR2?

    @treb0r said:

    does Domoticz support MySensors time function? That I do not know.



  • @BulldogLowell
    I am afraid that Domoticz doesn't have such advanced options of configuration of devices. Or maybe I am wrong? Is there any chance to bypass the V_VAR1 variables?


  • Hero Member

    @treb0r This thread seems to imply that V_VAR1 etc are supported. I guess @AWI can say more about that.


  • Contest Winner

    thanks for your help, @Moshe-Livne

    Do you know if Domoticz supports returning Unix timestamp using requestTime()?


  • Hero Member

    @BulldogLowell Sorry, I don't know.

    @treb0r,

    If you can find out if V_VAR1 & V_VAR2 can work you can try that. Otherwise we can hard code the watering times by zone into the programming.

    If requestTime() isn't supported, we can attach a Real Time Clock (RTC) device to gain back the clock functionality.

    You can then use the Domoticz devices to start the ALL_ZONE sequence or individual zones...

    Let me know what you would like to do and I can modify the program for you.



  • @BulldogLowell

    requestTime() seems not be supported. A have rtc ds3231 or ds1307. They can use the same commands and libraries. If you would change the code that would perfect 🙂 As you proposed you would also include in the code the timers for zones, instead of requesting them from Domoticz. As I understand these timers are only for manuals starts (via button) right?

    @treb0r said:

    @BulldogLowell

    Well, those times will be used when you activate the device using the Domoticz on/off controls (or activate using 'scene' in Domotocz.

    Give me a day or so and I will try to code for you.

    @treb0r

    Would you like to try this, untested.

    Just to see if the RTC is working...

    MySprinkler for MySensors
    
    Arduino Multi-Zone Sprinkler Control
    
    June 30, 2015
    
    *** Version 2.0nsr //MODIFIED FOR NO SHIFT REGISTER
    
    *** 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

  • @BulldogLowell
    HI
    Thanks for the post. On LCD there is no info about Time Synchronisation fail. It stops, as previously on info: Updating Valve : 0
    So I cant check if the RTC is working
    treb0r


  • Contest Winner

    @treb0r

    did you get your RTC connected and tested?



  • @BulldogLowell
    Yes, RTC is connected and tested with different sketches (just to check if RTC work correctly). Works ok.
    With your correctes projects, as above mentioned: On LCD there is no info neither about Time Synchronisation, nor about Time Synchronisation fail. It stops, as previously on info: Updating Valve : 0
    treb0r


  • Contest Winner

    Yes, since clock no longer needs to call server for time, synchronizing is not necessary.

    You should post serial output or show a video.

    Did you find out if Domoticz supports V_VAR1?



  • @BulldogLowell
    OK, I will post the video. If I will manage I will also post serial output
    treb0r


  • Hero Member

    @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


  • Hero Member

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


  • Hero Member

    @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....


  • Hero Member

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


  • Hero Member

    @epierre can you please link to the post?


  • Hero Member


  • Hero Member

    @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.....


  • Hero Member

    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


  • Contest Winner

    @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.



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

    Regards



  • 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.

  • Contest Winner

    @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.



  • Thx for the quick answer

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

    Regards



  • 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():

    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 👍

    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/

    * 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 ?


  • Admin

    @epierre Where did you see that I don't remember? Perhaps for the NRF radio?


  • Hero Member

    @petewill it is here: http://www.mysensors.org/build/irrigation

    it is hard to know the BOM from the page, so I was wondering why you would neeed the powering adaptation if you input 5V


  • Contest Winner

    @epierre

    If you watch the video, you can see he's using the voltage regulator to supply power to the radio.

    Are you getting ready to build?

    Are you getting ready to build?

    I've ordered the 8 switch, I have soil moisture, leaf moisture, ground humidity, rain gauge and found some evapotranspiration algorithm so I have all inputs and now need to have outputs in parallel of my rainbird scheduler (too dumb...)

    So I'm ready to build as you say 😉

    Excellent project.
    Can you help me with the android code, to send instrucctions from my cell phone to Arduino? like on-off light , bomb, etc.

    thanks for your time!
    best regards.



  • Excellent work. I need help with android code. Anybody can help me with this?

    thanks



  • Hi,

    I made the circuit, but later i realize it required vera controller to sync all the data. Is there other way or idea to send data to the built system.


  • Admin

    @shemmozhipandian Sorry for the delayed reply. It does require a controller (like Vera) but there are free ones out there. Take a look here: http://www.mysensors.org/controller/

    I know Domoticz is free and seems to be fairly popular here. There are others as well. If you find one you like you may want to write a quick post to check compatibility. I personally use Vera so I'm not sure how the others work.



  • Hello Pete, thanks for your hard work on this. Superb!
    I want to build a irrigation controller like your project but can't figure out hows the wiring. On the wiki an image is shown but I can't see what the connections are in this "virtual proto board"
    Is there something clearer or like a pinout to pin list?
    I'm using an Arduino Nano, so things will be something different.
    Thank you very much.


  • Admin

    @Sergio Jim (@BulldogLowell) posted some more details above but here is my fritzing project as well. Hopefully you can zoom in where you need to see more.

    Fritzing Irrigation Controller Wiring.fzz



  • Mmm... I finally assembled the device. But I'm having problems with it. It doesn't activate/deactivates the relays. I'm getting the power for the relay board from the nano itself. Could that be the problem?
    Also, my domoticz doesn't receive the off signal from the controller. (doens't turn the light off) and sometimes throws some error telling that can't contact the node.
    BTW I tried to contac Bulldogloweel without success 😭

    Yes, that is most likely the problem. Most of the relays I have used need more power than what the arduino can supply. Try feeding it more power (like from a phone charger).

    Also, my domoticz doesn't receive the off signal from the controller. (doens't turn the light off) and sometimes throws some error telling that can't contact the node.

    Check the serial monitor with debug enabled. Does this happen every time? It could be radio issues. Do you have a 4.7uf cap on the radio? Is it close enough to your gateway?



  • @BulldogLowell

    I need to add a relay for a master valve. This will open when any zone valves open. I think it could be mapped to All On 0(1) but I am not sure how to accomplish this. I don't know the code for that or electrical connection. I also noticed we are about maxed out of data (99%) using ProMini. Any ideas?


  • Contest Winner

    If you are worried about Program Space you can turn off Serial debug to rid yourself of a bunch of overhead in the sketch. I am not using String class so there is PLENTY of RAM and I've been using this for a while with no stack corruption issues:

    #define DEBUG_ON   // comment out to surpress serial monitor output
    

    if you propose to turn ON the master valve when each valve is cycled on, then I believe all you need to do is add that valve to the bitmask (logical OR) each time you updateRelays().

    void updateRelays(int value)
    {
      if(value)
      {
        value |= 0b0000000010000000;  // master is the eighth relay, there are 7 controlled in this example (active HIGH in this example)
      }
      digitalWrite(latchPin, LOW);
      shiftOut(dataPin, clockPin, MSBFIRST, highByte(value));
      shiftOut(dataPin, clockPin, MSBFIRST, lowByte(value));
      digitalWrite(latchPin, HIGH);
    }
    

    not tested



  • @BulldogLowell

    By commenting out the DEBUG, it went from 99% to 63% used memory.
    The modification to void updateRelays worked very nicely. I only wish the master control valve would remain ON during cycling through each valve (subjected to VALVE_RESET_TIME) as I am using it to control a chemical feed pump to prevent hydrogen proxide (30%) from entering my irrigation system.

    Awesome job and I am very pleased with your design.
    The only problem I had when building the controller was getting the LCD to communicate.
    I added this comment to my program under Instructions.



  • @BulldogLowell

    I ended up going a different approach. I modified the program so I could use Arduino digital pin6 as an output powering my master valve relay. I then added digitalWrite (masterValvePin, HIGH) where you have updateRelays(BITSHIFT_VALVE_NUMBER) to turn ON the valve. To turn off the valve I added a delay then digitalWrite (masterValvePin, LOW) to if (state == STAND_BY_ALL_OFF). This has tested perfectly for my situation.
    The only thing missing from the Controller is the ability to add the RainBird rain sensor to the board. I think the way of achieving this is an input to my Vera controller.


  • Contest Winner

    @fusion_man

    maybe we can add a rain sensor this season. It is a good idea to include it.



  • @BulldogLowell

    I already did and it is up and running. I used A0 as the input for the rain sensor. I can see the rain sensor in Vera as a motion sensor. I didn't post the code as I didn't want to offend the designer. Being a newbie, I didn't know how to handle this update.


  • Contest Winner

    @fusion_man

    why not just post your code? I'm sure the guy who wrote the original code won't mind, if you include his original notes and credits.



  • Quick question, semi also referenced on the openhab binding.

    Looking to use this with Openhab, I have managed to get it to work with the serial gateway, however i don't see a way i can pass out any configuration of a valve time, i can however trigger valves with a runtime of 0 seconds.

    Any ideas how i can amend this to either use a fixed runtime in the project (happy to run it in 1min increments trigged from openhab hydro sensor results)
