It would be cool if you could type a code into the keypad and it would set all your devices to an “away mode” ie lights turn off, thermostat adjusts and cams turn on, etc. It would be way more convenient on your way out to do this than having to get your phone out.
You could achieve this if you key off the trigger being the lock state, but until the API (IF/not when) is available, it’s hard to trigger off of anything directly for the keypad.
