A Z-Wave Plus contact sensor with a built-in temperature probe and tamper detection. At about £45 it is pricey for a magnet sensor, but Z-Wave's long range and low-interference 868MHz band suit outbuildings and thick walls. Only buy it if you already run a Z-Wave stick.
What can Home Assistant control on the Fibaro Door/Window Sensor 2 (FGDW-002)?
| Control | Type | What it does |
|---|---|---|
| Door/window | Binary sensor | Open or closed state |
| Temperature | Sensor | Internal temperature reading |
| Tamper | Binary sensor | Triggers when the sensor is removed |
| Battery | Sensor (%) | Battery level |
Pairs through Home Assistant's Z-Wave JS integration with a Z-Wave USB stick (Z-Wave UK 868MHz). Fully local. Entities are the door/window state, temperature, tamper and battery; the sensor is battery powered and sleeps, so changing its parameters happens at the next wake-up.
