4.2.11 Remove Device
For security reasons, each sensor can only be added to one account. If a sensor needs to be added to
another account, it must be removed from the previous account first. This can be done by tapping the
“Remove Device” command in the sensor page. It is strongly recommended to remove a device when it
is connected to the WiFi and the internet. In this case, after the “Remove Device” command is tapped,
the sensor will reboot to finish the removing step. Please wait about two minutes for the reboot to
complete before turning off the sensor. The sensor will first blink white light for about 30 seconds, then
display steady white light during reboot, and blinks white light again after reboot.
If for some reasons a sensor has to be removed when it is offline (this could happen when the sensor
could not connect to the WiFi and internet, and could not communicate with the app either), the
following scenarios will happen:
1. If after the offline removal, the sensor is powered on within the coverage of the same WiFi network as
the network it was connected to before the removal, the sensor will automatically connect to the server
via the WiFi network, and the server will instruct the sensor to reboot to finish the removal process from
the previous account. After the reboot, the sensor is ready to be added to the new account (the LED will
turn into flashing white light).
2. If after the offline removal, the sensor needs to be added to a new account that uses a different WiFi
network from the previous network, the sensor’s status will be displayed as “Added” when the app
