SONOFF - Zigbee IP65 temperature and humidity sensor with display

Introducing the SNZB-02WD

The SNZB-02WD is a Zigbee sensor that measures temperature and humidity. It features a 2.2" LCD screen that clearly displays data. Its IP65-certified casing incorporates a waterproof, breathable membrane, enabling the sensor to operate even in damp or foggy environments.

This means it can be installed near a window, in a garden or in a greenhouse. It is designed to be UV-resistant, ensuring durability even in direct sunlight. It also operates in cold environments, with an accuracy of ±0.2°C for temperature and ±2% for relative humidity.

The sensor uses the Zigbee 3.0 protocol and can be used with various hubs such as SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-E, ZBDongle-P, Echo 4th generation, Echo Show 2nd generation or Echo Plus 2nd generation. Note: Amazon hubs do not support humidity display.

It is also compatible with open source platforms such as Home Assistant, notably via SONOFF's Zigbee dongles.

Thanks to the eWeLink app, you can view data by day, month or up to six months back (up to 180 days of history). The application lets you export the data, so you can better understand the evolution of your outdoor environment and adapt the watering of your garden, for example.

You can also create automations or receive notifications of changes in temperature or humidity, for example: receive an alert if the temperature drops sharply in a terrarium in the event of a power failure, or automatically trigger a solenoid valve if the air becomes too dry.
