### What issue do you have? Please be as thorough and explicit as possible.

Since the addition of the door sensor accessory for the Eachen garage door, I cannot just tap on the garage door on the devices page on homekit app, when clicked it opens the accesory for you to toggle the switch, the functionality you only get when you force tap the accessory in homekit.
