A friend asked me to find out why his connected lightbulb app was asking for his location, so I ducked out to Australia’s favourite hardware store, Bunnings, and grabbed one to check out. The developer discloses on the app store that the precise location data collection is optional. What we have discovered in this Twitter thread is that if you try to pair one of their devices via Bluetooth scanning, the app opportunistically siphons up your GPS co-ordinates and send them over the Internet to a remote server.
