Ideal climate in every corner of your home
Do you want to ensure the ideal conditions in the nursery, cellar, or greenhouse? With coverage reaching up to 120 m², the SONOFF SNZB-02D sensor set lets you fully monitor your environment. The clear LCD display shows the readings at a glance, while if the values exceed the limits you have set, you receive an immediate notification on your smartphone.
Smart automations that take care of you
Forget manual settings and let your smart home do the work for you. You can connect the sensor with other smart devices so that your humidifier turns on automatically as soon as the humidity drops below 40%, or your air conditioning when the room gets warm. With support for Amazon Alexa and Google Home, a simple voice command is all it takes to find out the conditions in any room.
Absolute compatibility and easy management
Thanks to the modern Zigbee 3.0 protocol, the sensor integrates seamlessly into your ecosystem. It works perfectly with the NSPanel Pro, the Sonoff Zigbee Bridge, and Home Assistant as well. In addition, it gives you the ability to keep a complete record of your measurements for up to six months, so you can analyze trends and export your data whenever you want.
