Irrigation Controller (up to 16 valves with Shift Registers)

[johnecy]

I have the irrigation controller all setup and working. I have one problem though as soon as I power it up with 5 volts for the pro mini sometimes one sometimes all the relays come on. If I am not home the water runs all day is there a programing change or a wire change I need to make to stop this. I was using the old wire diagram without the pull up on pin 13 of the 74hc I changed to the new version and added the lines off code but it still does not help.

[gohan]

Are you setting all pins to low during setup?

So I had started this build going on a year ago but never finished it. That was before I found the easy newbie boards which is what I plan on using to resurrect this build. My question is, can this be built using a 3.3V pro mini, or should I be using a 5V one. I am just wondering if I need to set up my newbie board with a 3.3V regulator or not. My other question is on the resistors. I have a bunch of 1/8 watt resistors and was wondering if they would work or if I should go to 1/4 watt. I have all of the parts in my parts bin and with the newbie board it shouldn't take long to put it together, just need direction on those couple things.

[gohan]

It's hard to answer since you aren't providing many details like is it battery powered? What kind of valves are you using? What are you using those resistors for?

@gohan Sorry, I am talking about the schematic for the irrigation controller in the build section of the site. That is why I posted the question here.

One other thing that I just noticed, and I will post this in the easy newbie board thread also for @sundberg84, I noticed that there is a change in the pins that are broken out on the header on the left side of the board. This is the board that I am using for the build, and I was going to point out here that the schematic below shows to connect D7 and D8 to the shift register, but the REV 8 board that I am using does not break out D8. After looking at the site on the new REV 9 boards, which I have a batch of, he doesn't break out D7 or D8.. The wiring of the pins is completely different between the REV 8 and REV 9 boards. The reason I mention this is that I was going to write something up here explaining the build with a newbie board, but I think I will hold off as it might be confusing to many depending what REV of the board people have.

Another thing that I just notices is on the schematic. I have a copy of the schematic that I printed last year when I started this build. There has since been a change. In the old schematic that I have it shows the output enable (OE) pin of the shift register grounded, where in the one below, it showsit connected to D6 through a 1K resistor. I can understand that the change is to give arduino control to the output enable line, but because in the other schematic it didn't show D6 connected, and I didn't have D8 broken out, I used D6 in it's place. I may need to rethink some of this. In any case, I will need to make some changes to the sketch prior to uploading it.

OK, so I have this built this and have it mostly working with my Vera Plus. Below is a link to a video of a problem I am having.

http://www.dan.bemowski.info/videos/20170601_004213.mp4

So my sprinkler system has a pump start relay which gets turned on any time a valve is turned on. Because of this I made a slight hardware modification which thus required a software modification. For the hardware, I ended up using relay number 1 of my 8 channel relay board as my pump start relay control. This I have wired to pin A1. Relays 2 through 8 are connected to the shift register on Qb through Qh (outputs 2-8) skipping output 1. Because of this I had to change how the code defined which valve to start on. To do this, I changed the commented lines removing the (-1) on the bit shift. I made the assumption that in code, the relay numbers start with 0.

#ifdef ACTIVE_LOW
//#define BITSHIFT_VALVE_NUMBER ~(1U << (valveNumber-1))
#define BITSHIFT_VALVE_NUMBER ~(1U << (valveNumber))
#define ALL_VALVES_OFF 0xFFFF
#else
//#define BITSHIFT_VALVE_NUMBER (1U << (valveNumber-1))
#define BITSHIFT_VALVE_NUMBER (1U << (valveNumber))
#define ALL_VALVES_OFF 0U
#endif

Then I needed to define the pump start relay.

const int pumpStart = A1;

and then in setup I have this:

  pinMode(pumpStart, OUTPUT);
  digitalWrite (pumpStart, HIGH);

Lastly, to operate the pump start relay whenever a zone is triggered, this is the updateRelays() function:

void updateRelays(int value)
{
  if (value == ALL_VALVES_OFF) 
  {
    digitalWrite(pumpStart, HIGH);
  }
  else
  {
    digitalWrite(pumpStart, LOW);
  }
  digitalWrite(latchPin, LOW);
  shiftOut(dataPin, clockPin, MSBFIRST, highByte(value));
  shiftOut(dataPin, clockPin, MSBFIRST, lowByte(value));
  digitalWrite(latchPin, HIGH);
}

All of this seems to work. When I trigger a zone, I see the pump start relay kick on as well as the triggered zone relay. The only problem I have is that the screen keeps cycling valve data: (1-4) on the screen, as can be seen in the video clip.

Here is my entire modified sketch that I have uploaded:

/*
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/

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

@dbemowsk

what's happening in the Serial debug?

[dbemowsk]

I'll look later and report. Got company at the moment. The odd thing is that I can turn my zones on and they seem to run for the specified time just fine. It's only what I see on the display that is messed up.

[Black Cat]

I've just started playing with a Z-Uno and was looking at ways to use for a project like this.
I'm a believer in not re-inventing the wheel and it seem that all I would need to do is to delete the radio and re-code the sketch for the extra relays ( I have already built a 4 channel relay, it's just getting over the hurdle of learning about Shift Registers).
Do you think this is possible or would I be better just starting from scratch?

[BulldogLowell]

@Black-Cat said in Irrigation Controller (up to 16 valves with Shift Registers):

Z-Uno

wicked cool...

I'm in North America, so I have to stand by!

You you should be able to easily port this for use with Z-Uno...

[BulldogLowell]

@dbemowsk

yes, weird...

[Topdawg2881]

@dbemowsk
I had this same issue. What I did to fix the issue was I commented out in the void loop the line to goGetValveTimes. I then added the timeAlarms library and set a timer to get valve times once every five minutes. The section of code looks like this. Alarm.timerRepeat (300,goGetValveTimes);
I inserted that line as the last line of cade in the void setup

[dbemowsk]

Okay, so I was just looking over the code. I first did a search for "Valve Data:" as that was what was showing on the screen. I found that in the goGetValveTimes() method. According to the code, that is only supposed to show if the inSetup variable evaluates to true. I then searched on that variable, and in the code just before the setup() method, I see this:

bool inSetup = true;

But I don't see anywhere in the code where it sets that value to false. So every time the main loop() calls goGetValveTimes();, it is going to display that since inSetup never gets changed to false. At the very end of the setup routine I see this bit of code:

//
  //Update valve data when first powered on 
  for (byte i = 1; i <= NUMBER_OF_VALVES; i++)
  {
    lcd.clear();
    goGetValveTimes();
  }
  lcd.clear();

I think that it is just after that for loop, or after the lcd.clear(); that it is supposed to set inSetup to false. I have not tested this theory yet as I need to unmount my controller and open it up to push the new code to it, but I am pretty sure that this is the issue. That would explain why everything else with it appears to work normally.

I double checked with the example code on the build page to see if possibly I may have deleted something when doing my edits. Looking it over, I found the same thing. If you ask me, this looks to be a bug in the code and it should be fixed and updated.

[Topdawg2881]

@dbemowsk
I am in front of my computer and I have my controller in front of me and hooked up. Give me a couple minutes and I will run it. See what happens.

[dbemowsk]

I just made the change and tested it. That was definitely the problem. Works perfect now.

Not sure who can change the example code, but all that needs to be added is this:

//
  //Update valve data when first powered on 
  for (byte i = 1; i <= NUMBER_OF_VALVES; i++)
  {
    lcd.clear();
    goGetValveTimes();
  }
  lcd.clear();
  //Add this line
  inSetup = false;

[Topdawg2881]

@dbemowsk
You beat me too it. I added the same line in same location and it works perfect. Every so often I see the raindrop icon to show that it is pulling data to update the valve times.

[dbemowsk]

So it is definitely a confirmed bug. I ended up finding some old sample code from when I started this last year and this bit of code was actually in the setup method and not in goGetValveTimes:

      lcd.print(F(" Updating  "));
      lcd.setCursor(0, 1);
      lcd.print(F(" Valve Data: "));
      lcd.print(valveIndex);

So some time in the past year the sample code had been changed.

[BulldogLowell]

@dbemowsk

good to see you found it. I haven't looked at the code for two years, and mine is still working. (@petewill 's demo worked well too). there must have been some change that managed its way into the source

maybe look on GitHub and do a pull request if you the problem is there...

[tombstone]

Hi I just order all the parts that was listed. Do I need to read the 230 post or it's ok just watched the video.

[dbemowsk]

@tombstone You shouldn't need to read all the posts. Maybe just search the thread if you run into any snags. What kind of setup are you dropping this into? Do you currently have valves installed? Does your setup have a master valve or pump relay? Is it a standard 24V AC system?
