Hi, I have a OpenSprinkler Pi (OSPi) board with an attached Raspberry Pi 3. I can connect to the Pi using the web app, but when I try and run a station, I get 0v at the station pin. I am using a Multi-meter set to volts AC, when I check the power supply its shows 29.8 volts. But when I set a station to manually run in the app, I get 0v when checking between the common pin and the station pin. Any idea what might be wrong?
This has been resolved, thanks to Ray. He advised to reload the Pi 3 with the latest Raspbian image and re-load the OSPi firmware. Everything is working now.
