I’d love to have a device in my garage that broadcasts the lock code for my car to ensure that my cars are locked when I set my house to “Goodnight”. I have searched for Arduino and Raspberry Pi solutions, thinking that if I can get the lock bit working I could add vision for an integrated garage device for all my parking needs. I could see real value in a multi-purpose detector and transmitter for the garage.
I had the thought to cobble something together with an after market key fob, but I thought I’d ask here first.
