SONOFF SNZB-02LD - Smart Thermometer, White

The SONOFF SNZB-02LD IP65 Zigbee LCD Smart Thermometer with 1.5 m Probe is a smart temperature sensor for liquids and enclosed or hard-to-reach spaces. Its external probe measures from -40 °C to 115 °C, with a stated accuracy of ±0.7 °C. The 1.5 m lead lets the probe reach the measurement point while the main unit stays nearby, rather than being placed directly in a liquid or confined space. A 2.2-inch LCD shows the current reading on the device. Listed uses include monitoring tanks, aquariums, refrigerators, pipes, and greenhouses.

The housing is made from PC+ABS and has an IP65 rating for protection against dust and water jets. The product is listed for indoor or protected outdoor probe applications. For remote readings, it communicates over Zigbee 3.0 with a compatible hub; Wi-Fi is not supported. Compatibility includes eWeLink, while Home Assistant and Apple Home integration is listed through a Matter bridge. Setup uses the eWeLink app on iOS or Android with a compatible Zigbee hub. The battery-powered thermometer has a stated battery life of up to one year.
