Introducing the Sonoff SNZB-02LD sensor

The Sonoff SNZB-02LD is a smart Zigbee thermometer with LCD display and IP65 protection, ensuring stable operation even in humid and wet environments. It is made of food-grade 304 stainless steel and is resistant to both high and low temperatures.

Its 2.2″ LCD display clearly shows the current temperature in °C or °F. The UV-resistant design ensures a long life even when exposed to direct sunlight. The 1.5 m probe length allows accurate temperature measurement of liquids or confined spaces, even in places that are inaccessible to conventional sensors.

The SNZB-02LD is compatible with Zigbee nodes using the Zigbee 3.0 protocol, such as:
SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Echo 4th generation, Echo Show 2nd generation and Echo Plus 2nd generation.

You can also connect the sensor to open source platforms such as Home Assistant via the SONOFF ZBDongle series to create your own customised temperature management solution.

With the eWeLink app, you can monitor temperature data by day, month or up to 6 months back (up to 180 days of storage).
You can access the measurement history and export the data to help you plan, for example, the optimum temperature for your water tank.

Create smart scenarios in the app, receive notifications of unusual temperatures or set up automations based on temperature changes.
