Currently when a v2 sensor is removed from the wyze sense hub by pressing and holding the pair button, nothing happens. There is no notification, no alarm, or trigger whatsoever. Its not easy to do, but if someone was able to reach a entry sensor and unpair it they could then open said sensor without triggering an alarm. Wyze does not offer glass break, so if i broke a window and unpaired the sensor i could open the window without triggering the alarm at all. My suggestion would be when a sensor is unpaired a notification can be selected to be sent, and if the alarm is armed with home monitoring you can choose for it to trigger the alarm count down sequence or cause an immediate alarm.
