does it make any sense to hook in the light sensor for the doorbell
It's not that accurate really - it's good for telling between light and dark but I wouldn't use it for much else!
I assume I can't configure the bangle js "button" BTHome app to work while I'm connected via BT to my iphone as advertisements don't broadcast while a device is paired?
Actually it should 'just work' - new firmwares are able to advertise while connected if you use the right flag in NRF.setAdvertising :)
