That sounds cool, I don’t have a smart home setup, but Bluetooth sounds kinda nice to me for changing the temperature on the thermostat in the house, car not so much. Now I do know many people who use Bluetooth to cast their phone calls to their hands free devices in cars, as well as to hook up those diagnostic tools and have the error codes go to your phone instead of buying a product that costs hundreds of dollars to have a screen you would only use for that one purpose.
