WiFi Temperature Humidity Sensor

This white sensor monitors indoor temperature and humidity without a separate hub. It connects to a 2.4 GHz WiFi network and reports readings through the Tuya Smart or Smart Life app. The device runs on two included AAA batteries and fits in small spaces such as potted plants or humidors.

Suitable for home monitoring and automation

Buyers who want remote alerts and smart-scene triggers for heating, cooling or dehumidifiers will find this sensor useful. It also supports voice queries via Amazon Alexa for temperature readings. Users needing 5 GHz WiFi connectivity or a display on the unit itself should look at other options.

Check your network and mounting plans

Ensure your router broadcasts a 2.4 GHz SSID because 5 GHz is not supported. Verify that the Tuya Smart or Smart Life app is compatible with your phone. Decide whether you will place the sensor freestanding or use the supplied sticker and screws for wall mounting.

Questions about this item

Do I need a 2.4 GHz Wi-Fi network to connect the sensor?

Yes, the sensor only works with a 2.4 GHz 802.11b/g/n network; 5 GHz is not supported.

Will the sensor work with my existing Tuya Smart or Smart Life app setup?

Yes, it uses the same Tuya Smart or Smart Life app, so you can add it to current scenes and automations alongside other Tuya devices.

How can I verify the sensor is reporting correctly after I install it?

Check the app for live readings within the -20~60 °C and 0-100 % RH ranges, confirm the ±1 °C and ±5 % RH accuracy, and ask Alexa for the current temperature.
