SONOFF SNZB-02P Zigbee Temperature & Humidity Sensor with Alerts, 1-Pack | Zigbee Bridge-Hub Required

The Sonoff SNZB-02P Zigbee Temperature & Humidity Sensor is a simple and reliable way to track indoor climate in real time. It uses a high-accuracy Swiss sensor that gives precise readings with ±0.2 °C for temperature and ±2% RH for humidity.

This device runs on Zigbee 3.0 and pairs quickly with SONOFF hubs like iHost, NSPanel Pro, or ZB Bridge Pro. Since it doesn’t use Wi-Fi, it gives you fast and stable updates without adding extra load to your network. It sends reports every 5 seconds, so you can always see current room conditions in the eWeLink app.

The SNZB‑02P is powered by a CR2477 battery that lasts up to 4 years. It’s compact and easy to install using magnets, double-sided tape, or screws. You can place it anywhere—bedrooms, closets, storage rooms, or plant areas—to keep an eye on temperature and humidity.

This smart sensor also lets you automate other devices. For example, you can turn on a fan when it gets too hot or switch on a dehumidifier when the air is too moist. You can also set alerts to be notified if temperature or humidity goes beyond your preferred range.

With multiple SNZB‑02P sensors, you can monitor different rooms at once. Their small size and low power use make them ideal for whole-home coverage.

The sensor works smoothly with the eWeLink app, giving you control and insights wherever you are. It even supports historical data tracking when used with compatible Zigbee hubs.

The Sonoff SNZB-02P is a great choice for anyone looking to improve comfort, automate appliances, or monitor sensitive areas like greenhouses or server rooms. It’s smart, small, and easy to use—everything you need in a temperature and humidity sensor.
