Sonoff SNZB-02P Zigbee Temperature & Humidity Sensor

Sonoff SNZB-02P Zigbee Temperature & Humidity Sensor

The SONOFF SNZB-02P is a small battery-powered sensor that measures room temperature and humidity and sends the readings over Zigbee 3.0 to your smart home hub. It measures temperature to ±0.2°C and humidity to ±2% RH, and runs on a CR2477 coin cell battery.

Accurate readings: With a temperature accuracy of ±0.2°C and humidity accuracy of ±2% RH, the readings you see in the app stay close to the real conditions in the room. This matters when you use them to decide when to heat, cool, ventilate or dehumidify.

Fast updates: SONOFF states the sensor reports within 5 seconds when the temperature or humidity changes. Your hub therefore gets new values quickly and can use them in smart scenes, for example to control a fan or a humidifier.

Zigbee 3.0: The sensor connects over Zigbee 3.0 (IEEE 802.15.4) through a Zigbee hub, not directly to Wi-Fi. Once paired with the hub, its readings are available in your smart home app.

Long battery life: The CR2477 coin cell battery lasts up to 4 years, so the sensor can be placed and left without frequent battery changes.

Works with

Zigbee hubs and gateways listed as compatible: SONOFF iHost, SONOFF NSPanel Pro, SONOFF ZB Bridge Pro, SONOFF ZBDongle-E, Amazon Echo (4th Gen) and SmartThings hub.

Good to know

A compatible Zigbee hub is required; the sensor does not connect to Wi-Fi or to a phone directly. Battery life depends on use.
