I really like these, they use a single AAA, they are cheap but feel well built.
But
- Seeing they burn through batteries quite quickly
- Drop off zigbee2MQTT quite frequently and need repairing
But the big one that really makes this unreliable is that often the device is showing as connected and working. The door/window opens, the red light flashes indicating that the device has recognised the event, and yet nothing reported in zigbee2MQTT.
The worst combination, appears to be working and reporting but not reporting events.
I can see absolutely no use in a sensor that may or may not reports events especially related to doors or windows.
So having given these, 7 of them, a good go for a year I can report unless someone here comes up with a fix they will consigned to the trash, or at least put on the ‘dodgy’ pile in the hope they get upgraded and become reliable.
Anyone else with good/bad experiences with these?
