Irrigation Controller (up to 16 valves with Shift Registers)

[Mark Jefford]

@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 :P

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.

@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.

[rechin304]

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?

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

Pictures of the case project and how is arranged inside. Not yet on the final location, still testing.

Hi I just finished building my first project in arduino ( this one) but the code is too large now for the arduino memory its 32748 bytes could you please share with me the older version of the code / libraries to run it in code bender ?

[mfalkvidd]

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

[petewill]

@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]

Hi Pete thank you very much, I am using mysensors online editor , not sure if I should edit that code?

[hek]

It's not possible to disable this from codebender. You'll need to install the Arduino IDE onto your computer.

[David Mora]

@hek in computer I get this:
C:\Program Files (x86)\Arduino\libraries\LiquidCrystal\I2CIO.cpp:35:26: fatal error: ../Wire/Wire.h: No such file or directory

@David-Mora Maybe this will help:

[David Mora]

thank you for your help ! I just reinstaled arduino and now I getthis ( I just downloaded the I.5 and copy and paste all libraries in the libraries folder:
TENCIÓN: Categoría '' en librería UIPEthernet no es válida. Configurando a 'Uncategorized'
C:\Users\David\Desktop\IrrigationController\IrrigationController.ino:92:31: fatal error: LiquidCrystal_I2C.h: No such file or directory

[David Mora]

@David-Mora quite sad I´ve spent two days now installing and uninstalling arduino and libraries and no luck

[petewill]

@David-Mora Did you close all instances of Arduino and open again after you added the LiquidCrystal library? It looks like it can't find it.

[David Mora]

@petewill Yes Pete it doesnt work at all

[David Mora]

@David-Mora hope this is the right way to post the code finally the only mistake is

@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:

#define DEBUG

to

//#define DEBUG

Also, it looks like the Arduino IDE programmer isn't finding your Pro Mini. Did you select the correct Board and Port from the Tools menu? I don't have an Arduino next to me so my port isn't available to select but it should look similar to this (except you would choose your Port the Arduino is connected to):
