My fork has an example board in it. I've been using without issue for about 5 years now.

this need special board to connect to the PI or just any relay? if is just relay how i chose what pin to use? thanks

thanks nhorvath but I'm not expert on electronics or coding lol. i just start using raspberry pi for 2 month now for first time. i find another link but i try to install and no work lol.https://github.com/mrsharpoblunto/it-gets-the-hose-again
Standard Sprkinklers_pi assumes OpenSprinkler-style serial connection. The easiest option is to buy extender board from OpenSprinkler: https://opensprinkler.com/product/zone-expander/, it will give you 16 channels for $52.
In my home setup I'm using relay outputs (both parallel and serial hookup), but my version of the software is very different from Sprinklers_pi.
you have github link for your code?
Here is it: https://github.com/tony-osp/SmartGarden
But it is totally different system, it uses multiple RF-connected stations to control zones and sensors data collection.
toshibochan, My setup is using a simple relay board directly connected to my Pi. Since sprinklers_pi uses the wiringpi library, you'll want to refer to that pinout page:
Here's what I'm using for a 6 zone setup: Pi - Relay Board pin 2 - VCC +5 pin 9 - GND pin 12 - Relay 1 pin 13 - Relay 2 pin 15 - Relay 3 pin 16 - Relay 4 pin 18 - Relay 5 pin 22 - Relay 6
Don't forget to set the Settings->Output to Direct Negative. Good luck!
Thanks claytonzo! I will try this weekend! Today I make my account in wunderground website and have API key, but what is wunderground IP and PWS ID?
I used 38.102.136.138 as the IP. I didn't use a PWS and instead used my zip code. Once you enter it all in, go to Advanced->WUnderground Diagnostics and it should populate all of the fields with the current weather information.
this need special board to connect to the PI or just any relay? if is just relay how i chose what pin to use? thanks
