# SONOFF SNZB-02D

*SONOFF / SNZB-02D*

> The SNZB-02D needs a Zigbee 3.0 hub or coordinator. It reads temperature and humidity and shows the reading and battery state on its own LCD. It suits HomeKit users through an integration (a Matter bridge). Google Home, Alexa and Home Assistant users reach it through an integration (Zigbee).
