The SNZB-02WD is a Zigbee-compatible, LCD display smart thermometer that has IP65 protection, so it operates reliably in a humid, splashing environment or outdoor. 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.

SNZB-02WD 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. Within the app, you can create smart scenes, get notifications of abnormal temperature, or automate the devices based on the measured values.

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

Main features:

- Large, well-readable LCD display: Display real-time temperature and humidity values.
- 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 can get an immediate warning.
- Data History and Graph: You can view previous measurements and trends on your phone.
- wide measurement range:
- Temperature: 0 ° C 60 ° C
- 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)
- Some 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, communicating through a Sonoff Zigbee Bridge to the Ewelink cloud transmits data and we can control other Sonoff or Smartwise WiFi and Ewelink devices based on its measured data.

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