Sonoff SNZB-02LD ZIGBEE 3.0 IP65 LCD Display Thermometer with External Temperature Probe

Article description:

Zigbee temperature sensor with external sensor

The SNZB-02LD is a smart Zigbee thermometer featuring an LCD display and IP65 protection, designed to operate reliably in humid or splash-prone environments. Its housing is made from food-grade 304 stainless steel, resistant to both heat and cold. The 2.2-inch LCD screen clearly displays the current temperature in °C or °F. The sensor is UV-resistant, allowing for long-term use even under direct sunlight. The 1.5 m long external temperature probe enables precise measurements in liquids or enclosed spaces—ideal where conventional sensors fall short.

The SNZB-02LD is compatible with Zigbee hubs supporting the Zigbee 3.0 protocol, such as SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Amazon Echo 4th Gen, Echo Show (2nd Gen), and Echo Plus (2nd Gen). It also integrates seamlessly with open-source platforms like Home Assistant—via SONOFF ZBDongle-P/E, Home Assistant SkyConnect, Connect ZBT-1, or the Zigbee multi-adapter from SMLIGHT (SLZB series)—offering a fully customizable and local temperature management solution without reliance on the cloud.

Using the eWeLink app, temperature data can be viewed by day, month, or half-year, with up to 180 days of historical data available for export—perfect for tasks such as monitoring and managing water temperature in tanks.

Intelligent scenes allow notifications on temperature deviations and enable automations based on temperature changes.

Whether for food safety, animal husbandry, wine storage, or greenhouse management, the SNZB-02LD provides smart and precise temperature control.

2.2″ LCD Display: The current temperature can be read clearly and easily at any time on the large LCD screen.

External Temperature Probe: The 1.5 m long probe allows temperature measurements in liquids or enclosed spaces—ideal where normal sensors are insufficient.

IP65 Protection: Reliable operation even in humid or splash-prone environments.

Zigbee 3.0 Compatible: Supports Zigbee hubs with the Zigbee 3.0 protocol, e.g., Home Assistant SkyConnect, Connect ZBT-1, Zigbee Multi-Adapter from SMLIGHT (SLZB series), SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Amazon Echo (4th Gen), Echo Show (2nd Gen), and Echo Plus (2nd Gen).

Data History & Export: Temperature data can be viewed by day, month, or half-year in the eWeLink app (storage for up to 180 days). Historical temperature trends can be reviewed or exported.

Not compatible with Philips HUE Bridge, as Philips uses a proprietary Zigbee protocol that does not allow third-party devices.
