FAQ
How large is the device’s display screen?
The display screen is 50*70mm.
Which temperature and humidity sensors can the device connect to?
The device can connect to the following temperature and humidity sensors: Aqara Temperature and Humidity Sensor, Aqara Temperature and Humidity Sensor T1, and Aqara TVOC Air Quality Monitor.
Which thermostats can this device be connected with?
Compatible Aqara thermostats include Radiator Thermostat E1 and Thermostat Hub W200 in Zigbee mode through Aqara Home. IR air-conditioning control is available through Hub M3. Check current device compatibility and firmware in the app.
Where does the data for the Secondary Area on the device screen come from?
When the device is connected to an Aqara hub via the Zigbee protocol and linked to an additional temperature and humidity sensor, the Secondary Area will show the data from the sensor. If no sensor is linked, the Secondary Area will display the local weather information from online sources.
Will the wireless switch’s previously configured automations be affected after the device is connected to the thermostat?
Once the device is connected to the thermostat, the user will receive a notice that the previously set wireless switch automations are disabled soon, but your settings will be saved. When the device is disconnected from the thermostat, the wireless switch automations will be restored.
Why does the data refresh rate on the device screen differ from the data in the app?
The data refresh frequency on the device screen depends on the sampling frequency of the sensor, and the data refresh frequency on the app depends on the device data reporting frequency. The more frequently the device reports data, the faster the data refresh rate will be on the app, but the device's battery life will be shortened accordingly. Users can choose the appropriate sampling and reporting frequency according to their personal needs through the app.
Why is the data displayed on this device inconsistent with the data on the associated thermostat?
To save energy, the device communicates with the connected thermostat device once every 30 minutes to synchronize data. But, when any button of the Climate Sensor W100 is pressed, they will synchronize immediately. If the user has not changed the associated thermostat device data through the Climate Sensor W100, there may be a discrepancy between the displayed data on the thermostat and the data before synchronization.
Does the device support connecting to multiple thermostats?
Thermostat association follows the options available for your device in Aqara Home. Available controls and associations depend on the thermostat model and firmware; check the current device settings in the app.
Is the device waterproof?
The device is not waterproof and is for indoor use only.
What should be considered when installing or placing the device to increase the accuracy of the temperature and humidity sensors?
This device is for indoor use only and should be placed away from direct sunlight, obstructions, or heat sources.
