SONOFF SNZB-02WD Zigbee Temperature & Humidity Sensor

Monitor temperature and humidity in real time with the SONOFF SNZB-02WD, an IP65-rated Zigbee 3.0 temperature and humidity sensor with a clear 2.2-inch LCD display. Designed for smart home monitoring, it provides accurate readings while allowing compatible Zigbee gateways and platforms to access the sensor remotely.

Accurate Temperature & Humidity Monitoring

The SNZB-02WD measures both temperature and relative humidity with high accuracy. It provides temperature accuracy of up to ±0.2°C and humidity accuracy of up to ±2%RH, making it suitable for monitoring rooms, bathrooms, kitchens, greenhouses and other humid or splash-prone areas.

2.2-Inch LCD Display

View current temperature and humidity directly on the built-in 2.2-inch LCD screen. The display makes it easy to check environmental conditions without opening an app.

IP65-Rated Protection

The sensor uses an IP65-rated housing with a waterproof breathable membrane to help protect the device in humid and misty environments. It is designed for splash-prone conditions, but it should not be submerged, exposed to high-pressure water jets, or placed outdoors where it may be directly exposed to rain.

Zigbee 3.0 Connectivity

The SNZB-02WD uses Zigbee 3.0 (IEEE 802.15.4) wireless connectivity. A compatible Zigbee gateway or coordinator is required for app-based monitoring, automation and remote access.

Smart Home Compatibility

The sensor is compatible with supported SONOFF Zigbee gateways including SONOFF ZBBridge, ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost, ZBDongle-P and ZBDongle-E. SONOFF also documents compatibility with other Zigbee 3.0 gateways. Support and available functions can vary by gateway and platform.

The SNZB-02WD can also be integrated with supported smart home systems such as eWeLink, Home Assistant through ZHA or Zigbee2MQTT, and other compatible Zigbee 3.0 ecosystems.

Flexible Installation

Install the sensor using its magnetic mounting option or hang it using the lanyard hole. SONOFF also provides compatible 3D-printed installation accessories for additional mounting options.

Battery Powered

The SNZB-02WD is powered by a CR2477 coin-cell battery and uses a 3V input. Battery life can vary depending on usage, wireless conditions and configuration.

Q: Does the SONOFF SNZB-02WD require a Zigbee hub?

A: Yes. The SNZB-02WD uses Zigbee 3.0 and requires a compatible Zigbee gateway or coordinator for app monitoring, automation and remote access.

Q: What battery does the SNZB-02WD use?

A: It uses one CR2477 coin-cell battery and operates at 3V.

Q: Is the SNZB-02WD waterproof?

A: It has an IP65 protection rating and is designed for standard splash-proof and humid environments. It should not be submerged or exposed to high-pressure water jets. SONOFF also advises against placing it outdoors where it is directly exposed to rain.

Q: How accurate is the temperature and humidity measurement?

A: Temperature accuracy is up to ±0.2°C (±0.36°F), while humidity accuracy is up to ±2%RH.

Q: What is the operating temperature range?

A: The specified working temperature range is -20°C to 60°C (-4°F to 140°F). At extremely low temperatures around -20°C, SONOFF notes that measurement deviation, battery capacity and LCD refresh performance can be affected.

Q: What Zigbee gateways are compatible?

A: SONOFF lists ZBBridge, ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost, ZBDongle-P and ZBDongle-E as compatible gateways. Other Zigbee 3.0 gateways may also work, depending on their supported features.

Q: Can I use the SNZB-02WD with Home Assistant?

A: Yes. SONOFF documents integration with open-source platforms such as Home Assistant using compatible Zigbee coordinators and integrations such as ZHA or Zigbee2MQTT.

Q: Can I monitor temperature and humidity remotely?

A: Yes. When connected to a compatible Zigbee gateway and supported platform, the sensor can provide remote temperature and humidity monitoring. The eWeLink app also supports historical temperature and humidity data.

Q: Does the sensor have an LCD display?

A: Yes. It features a 2.2-inch LCD screen for viewing temperature and humidity readings directly on the device.

Q: How can I install the sensor?

A: The sensor can be mounted magnetically on a suitable metal surface or hung using the lanyard hole. SONOFF also provides optional 3D-printable mounting accessories.

Q: What happens if the Zigbee connection is unstable?

A: Check the distance between the sensor and gateway and reduce obstacles or interference where possible. SONOFF recommends no more than approximately 50 metres through walls and suggests using Zigbee router devices to strengthen network coverage when necessary.

Q: Why might some features be missing in eWeLink?

A: Make sure both the Zigbee gateway firmware and eWeLink app are updated. If the sensor was initially paired using outdated gateway firmware, SONOFF recommends updating the gateway and re-adding the device.

Q: Can the temperature unit be changed between Celsius and Fahrenheit?

A: Yes. Double-pressing the device button switches between °C and °F.

Q: What is the size of the SNZB-02WD?

A: The product measures approximately 62.8 × 58.5 × 21.8 mm and weighs approximately 65.6 g.
