Product information

Description

The Sonoff ZigBee Indoor Temperature & Humidity Sensor SNZB-02D is a compact wireless detector powered by a CR2450 battery, designed to monitor indoor climate. It features an integrated LCD display and supports Zigbee 3.0 connections for compatibility with most Zigbee gateways and hubs.

It supports instant mobile alerts via the eWeLink app when temperature or humidity exceed user-defined thresholds. With Zigbee 3.0 compatibility and Home Assistant support through the eWeLink add-on, it integrates into existing smart home systems. It offers up to 120 m (400 ft) coverage in ideal, unobstructed conditions and includes three mounting options for flexible installation.

How to use

Insert the CR2450 battery and place the sensor in the desired indoor location. Pair the device with a Zigbee 3.0 gateway or compatible hub following the gateway’s pairing procedure.
