I have some drippers connected to a valve controlled by a zoom relay.
like to control that relay by some parameters like before sunset or after sunset, winter spring summer fall, interval (like every hour), and duration (like 5 minutes)
Click search icon at upper right of this page, type in Simple Irrigation.
This is the first hit:
Click on the link to the thread, then in the thread click on the link to the GitHub.
