Buyer questions

Q: Does the SONOFF SNZB-02P work without a ZigBee bridge?
No, this sensor requires a ZigBee bridge or a smart home hub with an integrated ZigBee module. If your Alexa Echo has an integrated ZigBee hub, the sensor can connect directly to it without an additional bridge.

Q: What is the battery life and how do I replace them?
Batteries typically last for several months, depending on usage intensity. When the battery runs out, the app will notify you via a push notification. You can replace the batteries from the back by opening the magnetic cover.

Q: Is the sensor suitable for humid rooms, such as a bathroom?
Yes, the SNZB-02P is designed for humid conditions, but it is not recommended to place it directly in the shower or in a place where it may be splashed with water. If you want to monitor bathroom humidity, install it away from direct water contact.

The SONOFF SNZB-02P temperature and humidity sensor is a great investment in a smart home system. If you want to constantly monitor your home's microclimate and automate heating and humidification systems, this sensor is the ideal choice for you.
