Hi first Great projekt. All the things is Just ordred from eBay. But i Wonder what the yellow component is.

And mayby a tuturial have to make a complete HA kontroller. And have to set i Up. Rigtig now i have a raspberry pi with calaos. But i Dont know have to the it Up with the system.

Hope there is some help in here :)

Where are you seeing the yellow component? Maybe it's the LED? Can you post a picture?

[impertus]

@petewill this One.

[petewill]

@impertus Ah, ok. That is a .1uf capacitor.

[BulldogLowell]

@petewill

which can be easily substituted by a flux capacitor.

:wink:

[impertus]

@BulldogLowell Thx :)

Is this the rigth setup.

Irrigationcontroller <-----> Radio + ethernet (Gateaway) ------> Router + Wifi ------> RaspB with (Calaos HA controller)

Wifi -----> Calaos Mobile app

How does the HA controller detects the signal from the irrigation controller? some mystisk setup :) or plug an play..

What HA will you use (Opensouce)(With mobil function)

[petewill]

@BulldogLowell Ha! Unfortunately I'm fresh out of those...

@impertus Both @BulldogLowell and I use Vera as our home automation controller (not open source). My setup looks like: Irrigation Controller <> Ethernet Gateway <> Vera <> Vera Mobile App (usually AutHomationHD). I haven't tested any other controllers with this device but reading up a little in this forum post it appears that some people have got it to work with Domoticz.

[impertus]

@petewill yeahh i did a little bit of surfing on the forum. And felt over Domoticz. I see that also can run on RaspBerryPi. So think i will give that at try. It will be nice with a newbie guide how to setup my sensors to Domo. step by step..

now im waiting for the mailman with all my components :)

Hi, I've done recently this setup - it works greate with domoticz and Raspberry Pi 0.
After some tests I findout that when I plug in power - sometimes all, sometimes 3 or 4 relays are turning ON for 1second.
If that happend my 24V power adapter will be in trash. How to prevent that? Do I need to add something in code (I'm not a programmer)?

[BulldogLowell]

@Huczas

try adding a delay in various places in setup() start with 5 or even 10 seconds.

[Huczas]

ok, I just get back from Hackerspace. Some people fix this issue:
SN74HC595 - 13 pin (OE from datascheet) - remove GND and then add pull up 1k resistor and wire it to Arduino pin 6

and software, added three lines in code:

  const int outputEnablePin = 6;

  pinMode(outputEnablePin, OUTPUT);
  digitalWrite (outputEnablePin, LOW);

put them after 190 line https://github.com/mysensors/MySensorsArduinoExamples/blob/master/examples/IrrigationController/IrrigationController.ino

should be like that:

<some code>
 //Setup Shift Register...
const int latchPin = 8;
const int clockPin = 4;
const int dataPin  = 7;
const int outputEnablePin = 6;
//
byte clock[8] = {0x0, 0xe, 0x15, 0x17, 0x11, 0xe, 0x0}; // fetching time indicator
byte raindrop[8] = {0x4, 0x4, 0xA, 0xA, 0x11, 0xE, 0x0,}; // fetching Valve Data indicator
// Set the pins on the I2C chip used for LCD connections:
//                    addr, en,rw,rs,d4,d5,d6,d7,bl,blpol
LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);  // Set the LCD I2C address to 0x27
MySensor gw;
//
MyMessage msg1valve(CHILD_ID_SPRINKLER, V_LIGHT);
MyMessage var1valve(CHILD_ID_SPRINKLER, V_VAR1);
MyMessage var2valve(CHILD_ID_SPRINKLER, V_VAR2);
//
void setup()
{
  SERIAL_START(115200);
  DEBUG_PRINTLN(F("Initialising..."));
  pinMode(latchPin, OUTPUT);
  pinMode(clockPin, OUTPUT);
  pinMode(dataPin, OUTPUT);
  pinMode(ledPin, OUTPUT);
  pinMode(waterButtonPin, INPUT_PULLUP);
  //pinMode(waterButtonPin, INPUT);
  attachInterrupt(1, PushButton, RISING); //May need to change for your Arduino model
  digitalWrite (ledPin, HIGH);
  DEBUG_PRINTLN(F("Turning All Valves Off..."));
  updateRelays(ALL_VALVES_OFF);
  pinMode(outputEnablePin, OUTPUT);
  digitalWrite (outputEnablePin, LOW);
<some code>

If somebody can update this project in github and that fritzling draw - would be super nice.

[petewill]

@Huczas Great, thanks! Have you tested these updates? Also, can you post a link the info on hackerspace?

[Huczas]

@petewill
Yes, I've tested this and it's working well!
Link to the hackerspace - HackerSpace Warsaw, they are on irc - where I talk with them, #hackerspace-pl at freenode servers.

[petewill]

@Huczas Oh, ok. I thought it was a forum post. Thanks for the update. I will work to get this updated.

[petewill]

@Huczas the code has been updated in the 2.0 GitHub branch. The wiring diagram has also been updated. Thanks for the fix!

[Huczas]

@petewill as I sad before - pull up 1k resistor and wire it to Arduino pin 6 - I mean

pull up - connect to power,
so should be 1k resistor connected with power source(that make sence with pull up) and also with pin 6. Like below:

[petewill]

@Huczas Ah, missed that. I fixed it.

[bsivley]

I just finished building this but when I go to upload the code to my arduino i get this error

'byte clock [8]' redeclared as different kind of symbol

what does this mean ?

thanks

[petewill]

@bsivley Are you using the libraries from the MySensors github page (https://github.com/mysensors/MySensorsArduinoExamples/tree/master/libraries)? I just compiled it without any errors. What version of the Arduino IDE are you using? What version of MySensors are you using?

[Andrej_AB]

@petewill Hi, Please can you advise what version Arduino IDE you are using for this sketch?
