My New IrrigationController

Hello,
What have you used on the hardware side ?
The OpenSprinkler project is interresting as it is designed to run on arduino with some interresting logic such as EvapoTranspiration or the "Mr Zimmermann" method.
https://github.com/rayshobby/opensprinkler
It would be interresting to have it running on your domotiz platform and connect the remotes valves through mysensors ;-)
//and maintaining grass is more a problem than a solution, too many time and water wasted on it... (not talking of polluants...)

rfx - Domoticz <- MyDomoAtHome <- Imperihome

Hi there!Hardware (main):
Adruino MEGA256 - Nano and ProMini was to small with memory.
DS3231 - for RTC and temperature inside the box
LCD 4x20 I2C
Power supply 12V & 5V 2A each - part is from my "old" external HDD
NRF24L01+PA+LNA + Socket Adapter plate Board f 8Pin NRF24L01+
http://www.ebay.com/itm/311574056137?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Keypad 4x4
DS18 for temp - had DHT11 but mixed + & - and got burned down ;)
5V 8-Channel Relay Module With Optocoupler Low Level Triger
24V Transformer with DIN mountingThe most expensive single part was the BOX :)
I've visited before OpenSprinkler and this is a pretty nice project!

@marekd Great project and thx for the share! Are you sure you can't squeeze the sketch into a Nano or ProMini by using PROGMEM and F-macro? I did it like that in this example.

@m26872
Thanks!
You can squeeze, but I wanted to have more options and not to be limited by memory - anyway at this stage of developing. Because normally you have only one sprinkler controller you can use better uC - I did this way. Playing with more advance programming for memory optimization - is not for me (at this stage of my knowledge) - but thanks for this hint , I might use it in future.I was reading your post about 2AA battery node... this is my let's say next step to make.

on the OsPi hardware, both Arduino/PI (depending on installation) are powered from 24V AC for the sprinkler valves

@mareked you could power everything only from the 24V AC as they do !

power supply unit with LM2596 is rather complicated to build and needs parts which I don't have. I could, of course, buy step down module for around 1-2$. Maybe I'll come back to this solution after this watering season - now is is to late for this. Thanks anyway! -
Finally I launched my Irrigation System, there are some small bugs in the code, but can live with it - for now. Have plans how to rebuild this in winter time to be more robust and to look better.
Runs under Domoticz and manually with keypad.
For now it looks like this:
-
@epierre
Started to play with LM2596, I've got sth. like this:
http://www.ebay.com/itm/1pcs-1-23V-30V-DC-DC-Buck-Converter-Step-Down-Module-LM2596-Power-Supply-Output-/400985220074?hash=item5d5c94e3ea:g:o10AAOxy0x1TVSpDAdded diode bridge between transformer and this converter. But my concern is that I've some big voltage peaks the the output of it. It happens when I'm opening/closing valves (AC solenoids) connected to this transformer.
Set this converter to 12V DC but my readings are sometimes around 20V DC and I am affraid that I could destroy by Arduino.
Do you (anyone) have any suggestion ? -
Just wondering, could you not set your zones up as an array. This would reduce the size a little and should also free up memory for variables.
@gbgent_nc
Yes I could and did already because have to use ProMini [my MEGA2560 was killed ;) ].
Anyway plan is now to use 2xProMini., one for LCD, Keyboard, relays and second for temperature x2, water meter, rain sensor and relay for pump. -
@fets
Manufacturer is RAIN S.p.a Italy, www.rain.it.
Model I use is RN150.
Got them from Leroy Merlin, price was around 11 EUR. -
Last summer during vacation, was quite hot at my place. My green grass in the garden became ... brown and yellow - there was nobody to irrigate and was no rain, of course!
So I made a decision to buy irrigation controller and all that stuff. I wanted to have 7-8 zones, BT or wireless control, temperature and rain based control, RTC, Keypad, etc. The problem was that nobody had it or was to expencive.
So long story short I came up with idea to build one with all those features i need. Without having experience with uC I start to learn (google and youtube) a bit and build some "prototypes". Than IrrigatonController ver 1.0 was ready (December 2015):
Than I found @petewill IrrigationControler at youtube - but it was to hard for me from software (all this MySensors) and hardware side - I thought!
So I built new one - well it is almost done.
It is tested and working, few things are still missing like running without HA controller and rain sensor. Anyway I post some pictures and script what I've done. At my place it is working under Domoticz and manual (keypad). Tomorrow final wiring!
.Any comments are more than welcome, know that script need some more work - but it is just a beginning.

@marekd Great controller! For the keypad: I see from the code that you use the I2C code. How did you connect your keypad? Did you use a I2C extension chip? And, which keypad_i2c library do you use? I found multiple on the net.
Thanks!
@karl261
Thanks,
in case I2C yes, and no.
with 1st generation [with 1 ProMini] I used I2C port expander PCF8574.
with 2nd generation [with MEGA2560] just pins, 8 pins, declared like this:/**** Kepad settings /
const byte ROWS = 4;
const byte COLS = 4;
char keys[ROWS][COLS] = {
{'1', '2', '3', 'A'},
{'4', '5', '6', 'B'},
{'7', '8', '9', 'C'},
{'', '0', '#', 'D'}
};byte rowPins[ROWS] = {47, 45, 43, 41};
byte colPins[COLS] = {39, 37, 35, 33};
int i2caddress = 0x20;
Keypad_I2C kpd = Keypad_I2C( makeKeymap(keys), rowPins, colPins, ROWS, COLS, i2caddress );with 3rd generation - plan to have 2nd ProMini with PCF expander.
attached library I use.
