I checked the device and the screen on the unit is blank like it's not getting power. Could this be the battery in the sensor? Or could it be the unit has died or failed in some fashion?
The sensor worked fine last year, the system is running, but according to the faqs, a blank LCD means the unit is not getting power. Is this a Rachio fault then or a fault in the rain sensor? Any way to check the device if I disconnect it from the controller?
