    Hi there, I’ve left my Pi and OSPI on all winter long. Today I went to actually use it to water the lawn and it’s not working.

    The valves are working, the Pi is working, the webpage and Android app are working but when I try to turn on a station I hear no click from the relays and no valves turn on.

    I’ve removed power from the device and rebooted it. Still nothing.

    Anything else I can check?



    If you plug in 24VAC power, does the LED on OSPi lights up?

    The most common issue is the common wire not being connected or not connected correctly. Check the common wire.



    Just to close the loop on this thread. The problem was not with OpenSprinkler, but instead with my outdoor wiring. I discovered my irrigation installers did not use waterproof wire nuts on any connections. All outdoor wire connections were corroded. $10 on waterproof wire nuts and an hour of stripping back new clean wire and it’s back up and running.

    Thanks for the troubleshooting Ray!
