Add error for wrong HomeKit source

[metril]

I am running v1.8.4 of the go2rtc addon in Home Assistant 2023.12.

I have added the Aqara G4 Doorbell to Home Assistant via Homekit.

My go2rtc config looks like the following:

streams:
  aqara_g4_doorbell: homekit://some_address_here_copied_from_Add_tab_in_go2rtc
  
rtsp:
  listen: ":8554"
  username: "someusername"
  password: "somepassword"

webrtc:
  listen: ":9555"

homekit:
  aqara_g4_doorbell:
    pin: 12345678
    name: Aqara G4 Doorbell
    device_id: aqara_g4_doorbell
    device_private: aqara_g4_doorbell

I can see the Aqara G4 Doorbell in the Home app on IOS. I go to add it and then I get an error, unable to add accessory. In the go2rtc logs, I see:

ERR github.com/AlexxIT/go2rtc/internal/homekit/homekit.go:179 > error="ed25519: invalid params"

I expect to be able to proxy and successfully add the Aqara G4 Doorbell to the IOS Home app.

Try to use another pin. Something more random.

Same error. I've tried default pin and several random ones.

You should have pairings list in the go2rtc config. As I can see, you don't have it in your config.
Your error from Verify step. This means that Pair strep was successful. After pair step you should see pairing keys in config.

When I try to pair, I do see the pair key loaded into my go2rtc config. However, the IOS app complains that there was an error and then I don't see any new device.

Error in IOS app: "Unable to add accessory. An unknown error occurred."

I figured it out. There is some documentation that is missing. I also came across the Home Assistant forum post where someone had a similar issue and got it resolved. That post was also missing crucial information.

When you have the Aqara G4 Doorbell added to Home Assistant via the homekit integration, you need to then use the "homekit" URL listed under "Home Assistant" in the "Add" tab. If you use the homekit URL listed until "Homekit", then it will not work and you will get the error in the IOS Home App that I was getting.

[AlexxIT]

Yes, you're right. The HomeKit section is used to peer new devices. But your device is already connected to Hass. I need to rewrite error.
