I have a Gen 3. It has been working fine for a few years. However, now the unit does not activate any valves.
Controller and app indicate no errors; when a Quick Run is activated, the app shows that it is running, but the sprinkler does not turn on
Network updated & blue light on solid. (Note: I can successfully select the brightness level of the blue light, which indicates the Gen 3 is communicating with the network and internet.)
I can turn on any valve manually just fine, indicating that the water supply is OK
How do I troubleshoot this?
