ZigBee LCD temperature sensor Sonoff SNZB-02LD (with probe).

With the Sonoff SNZB-02LD smart temperature sensor, you gain complete control over the temperature in your home, garden or workplace. The device supports the Zigbee 3.0 protocol, and its compact design with a 2.2-inch LCD display and measuring probe provides extreme versatility in monitoring temperature - even in hard-to-reach places. Please note that the device requires a compatible Zigbee gateway to function properly. Managing the temperature in your home has never been easier!

Accuracy you can rely on

Using a food-grade 304 stainless steel probe, the sensor provides accurate temperature measurement with a tolerance of ±0.5°C over a wide range from -40°C to 115°C. Fast data updates every 5 seconds keep you informed of even the smallest temperature fluctuations – both in liquids and in enclosed spaces such as aquariums, refrigerators, wine cellars and freezers.

Built for special tasks

The UV-resistant housing and IP65 protection ensure reliable operation even in wet or splash-proof areas. It is ideal for monitoring temperatures outdoors, in the bathroom and even in water tanks. The 1.5-meter long probe allows you to measure temperatures in places that standard sensors cannot reach. Accuracy makes everyday life easier.

Data always at hand

With the intuitive eWeLink app, you can get even more options. With it, you can check the current temperature and monitor the measurement history for the last 180 days. A convenient daily, monthly or semi-annual overview will help you better manage the temperature in your water tank or refrigerator, for example.

Automate your home and respond instantly

The sensor, integrated with the eWeLink application, allows you to create smart scenes - from notifications when the set temperature is exceeded to automatically turning on the heating with devices such as ZBMINIR2. You can also control the temperature with your voice - all you need is a connection via a Zigbee gateway with a voice platform (such as Alexa or Google Assistant).

Integration with open source systems and convenient installation

The SNZB-02LD supports integration with open source platforms such as Home Assistant via the SONOFF ZBDongle series. This gives you complete freedom to create your own home automation scenes. The magnetic back plate and hanging bracket make the unit quick and easy to install.
