The SNZB-02P is Sonoff's Zigbee thermometer and humidity sensor, a 2023 product from the smart home device maker, a tiny wireless smart home sensor in a revamped guise using the Zigbee 3.0 protocol. The product includes a metal base that can be attached with a screw to which you can attach the device with a clamp inside the sensor, but it also comes with double-sided adhesive. The sensor measures the room temperature and humidity level and transmits the data via Zigbee gateway to control other devices.
For example, it communicates via a Sonoff Zigbee Bridge Pro or SmartWise Zigbee Bridge Pro to the eWeLink cloud and can control other Sonoff or SmartWise WiFi and eWeLink devices based on the measured data.

Improve the comfort level of your home: Wish your home always keeps a favourable temperature and humidity? Enable the smart scene to make the fan automatically turn on when the room temperature reaches 28ºC and the humidifier automatically turns on when the room humidity is below 45%RH.

Install in no time: Adopts 3M adhesives on the bottom of the sensor for flexible and fast installation on any surface of your home.

Low-battery notification: You will get a notification of low-battery level when the battery life gets 10% remaining.

Simply share the sensor to your family and they can directly check this temperature and humidity on their mobile phones without pairing it.
