Bought a Google Doorbell (battery) had an electrician hard wire it and the doorbell keeps telling me the battery is low and the device is offline. What a joke google devices have become! Wasted my money think: well that's a good idea if I ever loose power the battery will kick in and I will still get notifications, but the truth is the wiring is just a gimmick and won't do anything the device still runs off battery even after many factory resets tweak's and troubleshooting.
