Well, since you are using your own hardware, it’s difficult for me to help you diagnose. I think the issue boils down to activating your relay board — you can write a very simple program to test if each GPIO pin can activate the relay board. If this works, then it’s just the matter of plugging in this code to the OpenSprinkler firmware code, the rest of the firmware code should work as is.
