Sonoff Zigbee LCD Temperature & Humidity Sensor

The SONOFF SNZB-02D is a compact Zigbee temperature and humidity sensor designed for installers who need both smart monitoring and an easy-to-read local display. It provides real-time temperature and humidity readings on the built-in LCD screen, while also allowing remote monitoring through a compatible Zigbee gateway and smart home platform. SONOFF lists the SNZB-02D as a Zigbee 3.0 temperature and humidity sensor with a large LCD display, app alerts, historical data storage and export, and support for compatible Zigbee gateways. 

For trade customers, the SNZB-02D is a useful add-on for smart home, comfort monitoring and light commercial projects. It can be used in bedrooms, living areas, home offices, wine cellars, storage rooms, plant rooms, equipment cupboards, rental properties and other spaces where customers want better visibility of temperature and humidity conditions. The display also makes it easy for end users to check readings at a glance without needing to open an app.

The sensor uses a Swiss-made sensor and is specified by SONOFF with ±0.2°C temperature accuracy and ±2% RH humidity accuracy, with readings refreshing every 5 seconds. This makes it useful for comfort-based automations, such as turning on a fan when humidity rises, adjusting heating or cooling based on room temperature, or sending alerts when conditions move outside a preset range. 

When paired with a compatible Zigbee gateway, the SNZB-02D can send app notifications if temperature or humidity exceeds the customer’s preset comfort range. It also supports historical data storage and export, with SONOFF listing up to 6 months of free cloud storage for reviewing trends, highs and lows. 

For installers, the SNZB-02D is a simple way to add useful environmental monitoring to a Zigbee-based smart home system. It is battery powered, compact and easy to position, with mounting options suitable for walls, shelves, desks or other convenient locations. It is a strong upsell for Home Assistant, SONOFF Zigbee, Zigbee2MQTT and other compatible Zigbee installations where customers want automation, alerts and clear local readings.
