| Raspberry Pi GPIO doorbell button | Partly works | Rings, but Home app shows 'Not Supported' without a camera; needs GPIO pull-downSaved copyYes, the Apple Home App shows that the accessory is not supported. This is because the official HomeKit specification want’s the doorbell service to be exposed by a video doorbell. It should ring anyway. Could you please provide the following information: Enable Debug Mode, Ring the doorbell, send the Logs for that To which pins did you connect your doorbell on your pi? A scheme how the button is connected to your pi (photo also ok). Is the button directly connected, if not what is in between?

| Raspberry Pi GPIO pin 18 doorbell (new Raspberry Pi OS) | Not working | Button presses not registered; new OS GPIO numbering breaks rpi-gpioSaved copyOk, this is a problem with rpi-gpio. With the new Raspberry Pi OS, GPIOs are no longer numbered starting from zero. What you have to do is examine all of the gpiopinxxx nodes for their base and ngpio. As a workaround, you can edit rpi-gio.js and edit the two pin number tables to come up with the correct value. For example, pin 12 should have a GPIO number of 530 and pin 16 a GPIO number of 535. But rpi-gpio needs to switch to laying on top of libgpiod. Excerpt saved from GitHub on 2026-10-22. | Issue #4 · 2024-04 |

In ReReHome
Whatever this plugin publishes reaches Apple Home as a normal HomeKit accessory behind your Homebridge bridge, so ReReHome shows and controls it like any other.
Bridges get their own settings page listing the accessories behind them.
Caveats from the README
- Tested on Raspberry Pi only
HomeKit services in its code
Found by scanning the published npm package. A plugin can register a service only for some devices.
