SONOFF SenseGuard DW Gen3 door sensor adds Matter over Thread
Announced Sonoff
SONOFF is now selling the SenseGuard DW Gen3 (model SNZT-04P), a door and window sensor that can work in two modes: Matter over Thread or Zigbee 3.0. In Thread mode, SONOFF says it joins major Matter platforms directly, naming Apple Home, Google Home, Alexa, SmartThings and Home Assistant, without a SONOFF gateway. You do need a Matter hub that works as a Thread border router. Only one mode can be used at a time, and switching modes resets the sensor.
The sensor runs on two standard AAA batteries, which SONOFF rates at up to 15 months. It detects open and closed states with a 30 mm range when the magnet is mounted horizontally (15 mm vertically), and it has a tamper alarm that alerts you if the sensor is pulled off. In Thread mode, firmware updates come over Matter OTA. SONOFF also notes that SmartThings currently needs a script to use the sensor.
SONOFF lists the SenseGuard DW Gen3 at $22.90 (manufacturer price) on its own store.
