How to add the Aqara Temperature and Humidity Sensor to the Control hub? Move the Temperature and Humidity Sensor close to the hub, open app, go to the Device page of the hub, tap “Add device”, select “Temperature and Humidity Sensor” and add according to instructions. When the hub makes voice prompts, it indicates that it is added successfully. 2. Why does the Aqara Temperature and Humidity Sensor fail to connect? How to reconnect? Possible reason: * Operation error. Please add the device according to the adding method again. * The device is too far apart from the Hub. Please move the device closer to the Hub. * There are too many devices under the Hub. 3. Why is the Aqara Temperature and Humidity Sensor offline often? Possible reason: * If the device is too far apart from the Hub, please test the distance between the sensor device and the Hub and install the device closer to the Hub. * Low battery or no battery. Please replace the battery. * The device is installed on the surface and the signal strength is interfered . Please avoid metal surface. 4. How to verify that the current installation location is proper? After the Temperature and Humidity Sensor is connected successfully and before it is installed, press the button of the Temperature and Humidity Sensor, if the Hub gives a voice prompt “Connected Successfully”, current location is proper; if the Hub does not give a voice prompt, move the Temperature and Humidity Sensor closer and try again. 5. Attentions need to be paid while installing Temperature and Humidity Sensor: * The distance between the hub and the Temperature and Humidity Sensor should not be too far. Press the reset button before installation. After the hub gives a prompt of normal connection, install the sensor; * Paste or simply place it at your desired location; * Do not place it at a location exposed to rain or vapor if possible; * Do not install it in the refrigerator, kitchen or washroom if possible. 6. How to reset the Temperature and Humidity Sensor? If you do not want to use it or you want to add it under other hubs, press and hold the reset button for over 5s until the indicator flashes three times. Then the hub will give a voice prompt “Device Deleted”. 7. What is the function of the button on the Temperature and Humidity Sensor? Single press to check the connectivity to the Hub. It will report the temperature and humidity data to the Control hub. Long press to add and reset sub-devices. 8. Can the Temperature and Humidity Sensor be connected with the mobile phone directly? The Temperature and Humidity Sensor cannot be connected with the mobile phone directly. Please connect the hub with the mobile phone, and then connect the Temperature and Humidity Sensor with the hub. 9. What environment is the Temperature and Humidity Sensor suitable for use in? The Temperature and Humidity Sensor is suitable for indoor use. Normal operating temperature: -20~50°C; humidity: 0~100%, non-condensing environment. 10. What is the alerting mechanism of the Temperature and Humidity Sensor? When the Temperature and Humidity Sensor detects that current environment is out of the comfort zone, it will push notifications to the mobile phone. This function can be disabled in the app. 11. What devices can the Temperature and Humidity Sensor link? The Temperature and Humidity Sensor can work with other intelligent devices in Smart Home. For example, when the temperature is higher than the set value, the Temperature and Humidity Sensor will work with the Smart Plug to turn on the electric fan; when the humidity is lower than the set value, the Temperature and Humidity Sensor will work with the Smart Plug to turn on the humidifier. 12. What is the maximum responsive distance between the Temperature and Humidity Sensor and the hub? Are walls permissible in the range? Indoor responsive distance is about 10m (walls are
