WARNING: Sensor Firmware Issue: Check for Sensors Missing From Your System

This weekend while letting our dog out I noticed that I didn't get a tone when opening our back sliding door. After some investigation I found that sensor was missing from my devices list and all alarm history for it was missing from the list . I contacted support and found that there is a known issue with the sensors disappearing from the system due to firmware not updating. Someone could have walked into our backdoor with the system armed and we wouldn't have been the wiser. I have submitted a feature request for an email anytime a sensor is removed from the system.
