Doorbell over GPIO IN possible?

[MichlW]

First I want to say thanks for your great plugin. I use it to get the status of my water softener from a potential-free contact as error output wired to a GPIO IN of my Pi 4B.

Today I configured it to also get the event if someone pushes our doorbell button. Actually I use "Contact Sensor" for that purpose.

The Problem is, that i get two notification when pressed and when released. Also today i saw that you started to implement support for "Motion Sensor" over GPIO. Maybe this will resolve my problem, when do you plan to release the new version?

But...

Are you familiar with the accessory Doorbell? Maybe this is easy to implement to also use for GPIO sensor input?

I’ve never used it myself, but if memory serves, the Doorbell service only works in a Video Doorbell accessory. I need to have a look.

I plan to release a new version this weekend, with the motion device and with a separate accessory for the button devices as Home on iOS 14 no longer shows them when added to the RPi accessory.

I tried to expose an accessory with a Doorbell service, but it's not recognised by Apple's Home app. I double-checked using the HomeKit Accessory Simulator. The Doorbell service seems to be recognised only in an accessory that also includes an IP Camera. Exposing a fake camera just for supporting the Doorbell is a bit too much for Homebridge RPi.

Thank you for this information. I will try to configure a motion sensor from your plugin, a lock device and a camera in the same room. I heared HomeKit then acts automatically as such an Video Doorbell and i.e. provides a unlock button and a live image when motion is detected.

Maybe I can update this issue when its done (actually i do not have a suitable camera - searching for a cheap one supporting RTSP).

I opened #63 to also control a door opener from GPIO out using your plugin, that should act exactly as your already implemented switch device.
