    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.

    @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.

  • 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)


  • Contest Winner

    @Mark-Jefford

    In that case, I would just treat each zone as a separate relay/lamp and use Openhab to control the individual ON times... I think.



  • can I use pin D6 instead ok pin D8 to control the shift register. I am making the controller on the easy/newbie pc board and there is nothing connected to pin D8 on this board.


  • Contest Winner

    @johnecy

    const int latchPin = 8;
    

    I think you should be OK to try that



  • @BulldogLowell thanks for the reply i will post pictures when i get it finished



  • @BulldogLowell

    Gave up with using openhab now using domoticz which is a lot nicer, forced it to hard coded run times by doing this:

    else if (message.type == V_VAR1)
    {
    int variable1 = 5; // atoi(message.data);// RUN_ALL_ZONES time
    DEBUG_PRINT(F("Recieved variable1 valve:"));
    DEBUG_PRINT(i);
    DEBUG_PRINT(F(" = "));
    DEBUG_PRINTLN(variable1);
    if (variable1 != allZoneTime[i])
    {
    allZoneTime[i] = variable1;

          zoneTimeUpdate = true;
        }
      }
      else if (message.type == V_VAR2)
      {
        int variable2 = 5; //atoi(message.data);// RUN_SINGLE_ZONE time
        DEBUG_PRINT(F("Recieved variable2 valve:"));
        DEBUG_PRINT(i);
        DEBUG_PRINT(F(" = "));
        DEBUG_PRINTLN(variable2);
        if (variable2 != valveSoloTime[i])
        {
          valveSoloTime[i] = variable2;
          zoneTimeUpdate = true;
        }```
    

    one thing to note the shift register 0b0000000010000000 does not seem to work, will work out a plan around this as i need to run a 12 pump off the relay bank to draw water from the water butt.

    Can you explain more? is there a bug?



  • @BulldogLowell
    Hi! 🙂

    Rather than using valve 8, i am using only a block of 4, but currently have a 2 channel for testing.

    My reading into shift registers showed 0b0000000010000000 is 2x 8 bit outputs, B0-B7

    tried configuing B0 and B7 to try and activate relay 1, was still seeing 5V on all pins apart from the output pin for the zone in use (EG zone 2 expecting Zone1 to alway be on)

    or am i doing this completely wrong? 🙂


  • Contest Winner

    @Mark-Jefford

    hmmm... are your relays ACTIVE HIGH (actuate wiht a 5V signal) or ACTIVE LOW (actuate when brought to ground) type?



  • @BulldogLowell

    Oh, well this is strange, if i disconnect the pin to the relay, it does not activate when unpowered.

    but from the shift register it is +5 when the zone is not active, and 0V when active, so i assume its an active low not active high by your example... surely removing the 5V feed to the relay pin should make it activate.. not sure whats going on there, some sort of black magic 😛

    My reading of shift registers has made my brain hurt.. do i need to reverse the 0000000010000000 for 1111111101111111?



  • Dear all,

    i have trying to make the irrigation controller to start all zones in same time and run for the specified. I'm using version for domoticz. Can you please help me out with hint of what i can change in the code ?
    Another thing is that from domoticsz when i start a zone that zone start and previous is stopped but that status is not updated.

    Thank you in advance.

    P.S. I will post some pictures of the hardware build soon.


  • Contest Winner

    @rechin304

    have you tried changing the eight to one?

    #define NUMBER_OF_VALVES 8  // Change this to set your valve count up to 16.
    

    trigger all your relays with the same output.



  • Well, that's not the point.
    I will have 4 zones that need different type of water needs. For example one zone will be with micro irrigation watering, another one with lawn sprinkler. i do not understand why not to start all zones at once and they will finish according to the time set and not to start one after other. Another thing is why to wait for a zone to finish when you trigger another one.

    To start all valve at once when is trigger all zones i did change:

    else if (state == RUN_ALL_ZONES)
      {
        if (lastValve != valveNumber)
        {
          for (byte i = 0; i <= NUMBER_OF_VALVES; i++)
          {
            if (i == 0 || i == valveNumber)
            {
              gw.send(msg1valve.setSensor(i).set(true), false);
            }
            else
            {
              gw.send(msg1valve.setSensor(i).set(false), false);
            }
          }
        }
        lastValve = valveNumber;
        fastToggleLed();
        if (state != lastState)
        {
          valveNumber = 1;
          updateRelays(ALL_VALVES_OFF);
          DEBUG_PRINTLN(F("State Changed, Running All Zones..."));
        }
        unsigned long nowMillis = millis();
        if (nowMillis - startMillis < VALVE_RESET_TIME)
        {
          updateRelays(ALL_VALVES_OFF);
        }
        else if (nowMillis - startMillis < (allZoneTime[valveNumber] * 60000UL))
        {
          updateRelays(BITSHIFT_VALVE_NUMBER);
        }
        else
    

    with

    else if (state == RUN_ALL_ZONES)
      {
        if (lastValve != valveNumber)
        {
          for (byte i = 0; i <= NUMBER_OF_VALVES; i++)
          {
            if (i == 0 || i == valveNumber)
            {
              gw.send(msg1valve.setSensor(i).set(true), false);
            }
            else
            {
              gw.send(msg1valve.setSensor(i).set(true), false); //to update domoticz
            }
          }
        }
        lastValve = valveNumber;
        fastToggleLed();
        if (state != lastState)
        {
          valveNumber = 1;
          updateRelays(ALL_VALVES_OFF);
          DEBUG_PRINTLN(F("State Changed, Running All Zones..."));
        }
        unsigned long nowMillis = millis();
        if (nowMillis - startMillis < VALVE_RESET_TIME)
        {
          updateRelays(0); //all outputs will be on
        }
        else if (nowMillis - startMillis < (allZoneTime[valveNumber] * 60000UL))
        {
          updateRelays(BITSHIFT_VALVE_NUMBER);
        }
        else

    I see your point an understand your questions. The purpose of zone cycling is to be able to have enough pressure in each zone independently while also having pressure for household use. Drawing water to every zone (in my case 9) makes the pressure so low, there may not be enough to open the individual pop-up valves, much less fill the washing machine.

    The wait period (which you may set) is there to allow the time for hydraulic actuation of solenoid valves. These types of valves close slowly, and since they are in a manifold, the next valve to start opens faster if the water pressure at the manifold is allowed time to reach normal static pressure.

    The beauty of open source is that you get to do it your way. If you have the pressure to run all your valves at the same time, with enough to spare to take a shower, then you are fortunate!

    So, did you add another 'switch' to your controller to send the all zone command?



  • @rechin304 said:

    {
           updateRelays(0); //all outputs will be on
         }
    

    I did this so all relays on is ok now.
    What i miss is to start individual zones more than once at a time :).

    @David-Mora's question was double-posted. See https://forum.mysensors.org/topic/3921/code-grew-larger-dan-promini/ for the other thread.


  • Admin

    @David-Mora I responded to your comment on the YouTube video but I'll respond here as well just in case people are reading this thread instead.

    This is probably because debug is enabled in the MyConfig.h file. Please comment out this line: #define DEBUG
    Make sure to save the .h file then recompile the Arduino code. It should be around 25,342 bytes.

    @David-Mora Looks like you are almost there!

    Did you disable debug? The sketch looks too big. To disable go to the MySensors library and open the MyConfig.h file in Notepad and change this line:

    to

  • Thanks for posting, Mark. I was getting nuts figuring out what was the problem with my controller that was only activating 1sec each phase. I didn't implement it because that problem.



  • @Sergio-Rius no problem, i had plenty of issues trying to get this to work with openhab before i changed controller 🙂



  • So I have been thinking of building one of these. I have just ordered an 8 channel relay board from ebay. http://www.ebay.com/itm/5V-8-Channel-Relay-Board-Module-for-Arduino-Raspberry-Pi-ARM-AVR-DSP-PIC-MUC-/262472832393?hash=item3d1c999589:g:sDEAAOSwnFZXVj2p . I have been trying to sift through this thread and am not seeing what I am looking for. Does this project take into account a pump start relay? If not, I am wondering the best way to handle this. I only have 4 zones in my irrigation setup, so I could certainly use one of the relay channels for that if it is written into the sketch. One thought I had to save extra processing on the sketch in dealing with the shift register would be to put a diode on each output that would funnel to a single point, so whenever any relay is turned on the pump start connection point would go active. I would assume that something has already been calculated in for this, but I din't see anything.

    Thanks for the great project. The Youtube video for this is actually what got me started with MySensors in the first place.



  • I'm going down the diodes route... another channel to trigger it is tricky to deal with unless you use normally off relays and use the code earlier in this thread. I tried to use it but use normally on relays so going for diodes.

    K.I.S.S - keep it simple stupid 😉 no point making it harder for you if you have a workaround on the table 🙂



  • @Mark Jefford I can go that route, I just didn't know if someone already had that factored in to the project already. After thinking about it since I posted this, I could also go the route of using another single digital channel and wire it to one of the relays. Going that route would give me a couple things:

    • One I could turn on the pump independent of a zone because I have a faucet connected to the setup that I can use. Currently I have to turn on a zone to use the faucet.
    • Two, I could poll the state of the pump by checking the state of the one channel.


  • @Mark-Jefford I have the same issue. My system can't pass verifications for clock and valve data when I first plugged in because I don't know how to use this programs (Openhab, domoticz, etc.). Thank you!



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

              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"));
    


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



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


  • Admin

    @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.



  • 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. 🙂



  • 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

    @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.



  • Thank You, petewill I adjusted the wiring!
    0_1468603030032_upload-e9f66bab-6c30-42eb-80b2-da87857849e7
    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....

    EDIT: My condenser is 10uF / 63v



  • 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?


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


  • Admin

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



  • 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.



  • @Ngwpower which sketch are you using?



  • @Lars65 Thanks
    June 2, 2014 12:00 Version 1.0 Arduino Multi-Zone Sprinkler Control



  • @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.


  • Admin

    @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?



  • 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!



  • @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.



  • @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



  • @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:

    WARNING: Category '' in library UIPEthernet is not valid. Setting to 'Uncategorized'

    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.



  • @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?



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



  • @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



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


  • Hero Member

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



  • @Lars65
    Tried your sketch as well as a few of my own adjustments, still getting
    Yard_Sprinklers_revised_7-20.ino:85:18: fatal error: Time.h: No such file or directory.
    At a loss of where I missed this in the library!
    Rather be riding my scooter! got to get it done!



  • @AWI
    I'll try it.

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



  • @Sergio-Rius Really confused found these in AVR libraries on my computer. 0_1469044384924_upload-b0e77311-082b-4d33-9473-c59ef1302d37

    I'm currently looking at converting the sketch to v2.0



  • This post is deleted!


  • Hello, is there anyone who can explain to me step by step how to deal with these libraries ? I received this error when compiling :

    "C:\Users\witkowski.med\Downloads\IrrigationController\IrrigationController\IrrigationController.ino:85:22: fatal error: MySensor.h: No such file or directory

    #include <MySensor.h>

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



  • @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:

  • @rechin304 - that's a great case/box. Where did you purchase it?





  • 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.
    alt text
    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.



  • 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.
    A/V switcher front
    A/V switcher back
    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).
    relay/power boards
    AMS1117 regulator
    I cut a slot in the front of the case to allow access to the relay connections.
    front cutout
    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.
    screw terminals
    main board
    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.



  • 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?



  • 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.

    /*
    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

    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 🙂



  • @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.



  • @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.
