According to Apple's policies, location permission is now needed for the Bluetooth Alert (iBeacon) feature on iOS devices.*
Thus, the SwitchBot App must get access to location service to make Meter's alert feature work properly.
SwitchBot never tracks users' location information, nor do we share with any third parties.
If you are still concerned about it, we recommend you to pair your Meter with a Hub Plus and enable the Cloud Service of the Meter. In this way, your Meter's alert notificatIon will go through the Internet instead of Bluetooth, therefore location permission is not needed.
