The SNZB-02LD is a Zigbee-compatible, LCD display smart thermometer that has IP65 protection, so it works reliably in a humid, splashing environment. The device's sensor probe is made of 304 food stainless steel, resistant to high and low temperatures. The 2.2-inch LCD display is well read in the current temperature in ° C or ° F. Due to its UV resistant design, it is resistant to direct sunlight in the long run. The 1.5 -meter sensor probe allows you to measure the temperature of closed spaces or liquids - even in places where conventional sensors do not fit. SNZB-02LD is compatible with central units using the Zigbee 3.0 protocol, such as Sonoff Ihost, Nspanel Pro, Zbbridge-P, Zbridge-U, Zbdongle-E, Zbdongle-P, and Echo 4, Echo Show 2, Echo Plus 2. Also, with Open-Source platforms like Home Assistant, you can also integrate with the Sonoff Zbdongle series-making it easy to build your own customized temperature monitoring system.

In Ewelink application, you can look back at temperature data daily, monthly or half -yearly with a storage capacity of up to 180 days. You can share or export the graphs as you like. You can create smart scenes within the app, get notifications of abnormal temperature, or automate the devices based on the measured values.

Food safety, pet maintenance, wines storage or regulation of greenhouses-SNZB-02LD provides an accurate and smart solution for all situations.

Main features

- Large, well-readable LCD display: Display real-time temperature and humidity values, even with a probe.
- External sensor probe: For more accurate measurements, especially in places where the air is slower.
- Zigbee 3.0 Protocol: Stable, reliable connection, can be integrated into a smart home system.
- Real -time notifications: If the temperature or humidity exits the set range, you will receive an immediate warning.
- Data History and Graph: You can view previous measurements and trends on your phone.
- wide measurement range:
- Temperature: -40 ° C +85 ° C (with probe), 0 ° C 60 ° C (without probe)
- humidity: 0% 99% RH

Integration and compatibility

This device is fully compatible with the Sonoff Zigbee Gateway and other Zigbee 3.0 Hubs such as:

- Amazon Alexa (Echo Hub tools)
- Samsung Smartthings
- Home Assistant (Zha, Zigbee2mqtt)
- Tuya Zigbee Hubs

It can be used in any smart home system where Zigbee 3.0 support is available, so it can be easily inserted into automated rules such as temperature-based heating or humidification.

For example, a Sonoff Zigbee Bridge communities transmits data to the Ewelink cloud and can control other Sonoff or Smartwise WiFi and Ewelink devices based on its measured data.

The device is equipped with a Swiss hygrometer sensor that promises more accurate measurement than before, measuring ± 0.2 ° C/± 0.4 ° F at temperatures, and in case of humidity in ± 2%RH, the combined temperature and humidity sensor with 5 seconds.
