contact sensor low signal/battery drain

I recently installed a ring alarm system with several contact sensors on doors and windows. One of the contact sensors immediately began complaining about having poor reception and drained the new battery within a few weeks. The same behavior exists when the sensor is only a few feet from the base station.

Is it likely that the sensor is defective? Any procedures to follow to perform a braindead/cold reset of the device to see if it helps?

Hi @xcrracer. You can try factory resetting your Contact Sensor and seeing if this helps! I recommend to remove the device from your account first, then perform a factory reset, and after that, set it up again and watch it!
