When installing the Tapo P100 there are several permissions that the plug will ask for such as Bluetooth, Location Access, and Location Permission.
For Android you will see this screen:
For iOS you will see these screens:
Bluetooth is used to talk and configure the device rather than using Wi-Fi.
Location Access, and Permission are both used to work in conjunction of schedules and time settings of the plug.
During installation all three need to be enabled/allowed, once the plugs are set up you can go back and disable those options if you would like. Should you have issues after of schedules not working or any time settings you will need to go back into your smart phone app settings and enable those privileges.
