Have had an 8 zone Gen 2 since last May, no issues until a few days ago. Noticed that none of my zones were running, although the app indicated that everything was normal. I went to check the wiring today with a multimeter. Found that when any zone was activated manually via the app, all zones were receiving 24V. To try to isolate the fault, I then disconnected all wiring and ran each zone again. This time, the zone commanded to run was receiving 24V, and the others were reading around 10V. I would expect that only the zone commanded to run receives 24V and the others should be at 0. Any ideas? Defective controller? Wiring fault?
Nothing running, all zones reading 24V at controller

Sometimes a controller output will put out what’s called ‘ghost voltage’ on other terminals. It’s usually not enough to activate a zone, though.
Reboot the controller and recheck the output.
