What does "open box" mean?
Open-box products are returned products with opened or damaged packaging, but fully checked from a technical point of view and completely functional. They come with the same warranty as new products.
Sonoff SNZB-02D – Zigbee temperature and humidity sensor with LCD display
Smart monitoring of ambient comfort, with a clear display and Zigbee 3.0 integration!
Note: This product uses the Zigbee protocol and requires a compatible Zigbee hub/bridge (e.g. Sonoff ZBBridge-P / Sonoff ZBBridge-U / Sonoff ZBDongle-E / Sonoff Dongle-M) to be connected to the network and controlled from the app. It does not work on its own over WiFi.
Sonoff SNZB-02D is an advanced temperature and humidity sensor, equipped with a 2,5" LCD screen that displays the measured values in real time. Its compact design and extended functionality make it ideal for any smart home.
Flexible installation
It can easily be mounted anywhere in the home, using:
The included desk stand
The built-in magnet for fixing to metal surfaces
Double-sided adhesive tape
The small size (62,5 × 59,5 × 18,5 mm) and weight of 69,5 g allow discreet integration into any décor.
Smart automations
Through the eWeLink app, you can create automated scenes, such as:
Turning on the fan when the temperature exceeds 28 °C
Activating the humidifier when humidity drops below 45% RH
It works perfectly with compatible gateways, such as the Sonoff Zigbee Bridge Pro, SmartWise Zigbee Bridge Pro or NSPanel Pro.
Extended battery life
Powered by a CR2450 (3V) battery, the sensor offers a battery life of up to 2 years. The app notifies you when the battery level drops, ensuring continuous, uninterrupted operation.
Easy sharing
You can share the sensor with family members, letting them monitor temperature and humidity directly from their mobile phones, with no additional setup.
Turn your home into a smart and comfortable space with the Sonoff SNZB-02D!
Practical use cases
