SONOFF SNZB-02D (4-pack) - Zigbee 3.0 Temperature and Humidity Sensor, White

The SONOFF SNZB-02D Zigbee 3.0 Temperature and Humidity Sensor, 4-Pack reports temperature and humidity in indoor spaces. Its temperature accuracy is rated at ±0.2 °C. A built-in LCD shows the current readings on the sensor itself, so measurements can be checked locally. When connected through a compatible Zigbee hub, readings can also be viewed remotely in the eWeLink app. The app supports environmental alerts and historical data tracking, with up to six months of stored data. The sensors are intended for monitoring conditions across indoor spaces such as bedrooms, offices, and storage areas.

Compatibility includes SONOFF Zigbee hubs and compatible Zigbee ecosystems, while Apple Home support requires a Matter Bridge. The sensors use a PC housing and LCD display. Each unit can sit on a tabletop, attach to a magnetic surface, or be fixed with the included 3M adhesive. Wireless installation avoids the need for a power cable at the placement point. Power comes from a replaceable CR2450 battery, and batteries are included. The sensor can indicate when its battery is running low.
