SONOFF Zigbee Temperature & Humidity Sensor

Splash-Proof Temperature & Humidity Monitoring

The SONOFF SNZB-02WD is a Zigbee 3.0 temperature and humidity sensor designed for environments where standard indoor sensors may not provide sufficient protection. Its IP65-rated housing helps protect the device in damp and splash-prone areas while allowing you to monitor temperature and humidity in real time.

Clear 2.2″ LCD Display

The SNZB-02WD features a 2.2-inch LCD screen that provides an easy-to-read display of the current temperature and humidity. This allows you to check environmental conditions directly from the sensor without needing to open the app.

IP65 Protection for Damp Areas

The sensor features an IP65-rated housing with an internal waterproof breathable membrane. This design helps protect the internal sensor while allowing it to measure the surrounding temperature and humidity. It is suitable for humid or splash-prone environments such as bathrooms and other indoor areas exposed to moisture.

Important Splash-Proof Limitation

The IP65 rating is intended for standard splash-proof applications. The SNZB-02WD should not be submerged, exposed to high-pressure water jets or placed outdoors where it may be exposed to rain.

Accurate Temperature & Humidity Measurement

The SNZB-02WD provides temperature accuracy of ±0.2°C and humidity accuracy of ±2% RH, allowing you to keep track of changing environmental conditions with reliable readings.

Real-Time Environmental Monitoring

Monitor temperature and humidity through the LCD display and, when connected to a compatible Zigbee gateway, remotely through the eWeLink app. This makes it easy to keep track of conditions in different areas of your smart home.

Historical Data & Data Export

The eWeLink app can store temperature and humidity information for up to 180 days. Historical readings can be reviewed by day, month or over longer periods and exported for further analysis.

Smart Alerts & Automation

Create smart scenes based on temperature or humidity changes and configure notifications for abnormal environmental conditions. The SNZB-02WD can be incorporated into automated routines with compatible Zigbee smart-home devices.

Zigbee 3.0 Connectivity

The SNZB-02WD uses Zigbee 3.0 and works with compatible Zigbee gateways, including SONOFF iHost, NSPanel Pro, ZBBridge-P, ZBBridge-U, ZBDongle-P and ZBDongle-E.

Home Assistant Integration

The sensor can be integrated with open-source smart-home platforms such as Home Assistant when used with suitable SONOFF Zigbee hardware. This allows temperature and humidity information to become part of customised monitoring and automation systems.

Flexible Installation

The SNZB-02WD provides several installation possibilities, including its magnetic back and hanging point. Additional mounting options and 3D-printed accessories can also be used for specialised installations.

Ideal for Humid Indoor Environments

The splash-resistant design makes the SNZB-02WD particularly useful for areas such as bathrooms, kitchens, laundry areas and other indoor locations where humidity or occasional water splashes may be present.

Smart Home Climate Monitoring

Use the SONOFF SNZB-02WD to monitor environmental conditions and build smarter routines around temperature and humidity. With a compatible Zigbee gateway, readings can be monitored remotely, stored historically and used to trigger other smart devices.

Please Note

The SNZB-02WD is a Zigbee device and requires a compatible Zigbee gateway or coordinator for smart-home connectivity and app-based features. The IP65 rating is intended for splash-proof use and does not mean the device is waterproof for submersion or outdoor rain exposure.
