Can't access hkcam with Apple's Home app about hkcam

[brutella]

Take a look at the log file when you try to add the camera to HomeKit.
You can access the log file as described here.

Log file is like this :

`pi@raspberrypi:~ $ tail -f /var/log/hkcam/current

2019-06-22_12:30:51.28658 DEBUG 2019/06/22 13:30:51 camera_control.go:194: {"assets":[]}
2019-06-22_12:30:51.30193 INFO 2019/06/22 13:30:51 ip_transport.go:186: Listening on port 38251
`

No information is logged when I try to connect. But I see this device in Home App. I put in the PIN and ... nothing happens.

[brutella]

It seems like iOS has problems connecting to the device.
Do you have other Raspberry Pis with the same hostname connected to your WiFi network?

[RaymondMouthaan]

I have a similar issue .. I ran hkcam just fine, but after changing the hostname and removing the accessory for the Home App and re-adding it, It just doesn't appear in the app.

[brutella]

You can reset hkcam completely by deleting the folder /var/lib/hkcam/data.
The next time you boot the Raspberry Pi, you should be able to pair it with HomeKit again.

@brutella I had another RPi in the network, but with a different hostname. Even when I disconnected it ( ony RPi Zero with hkcam now in that network) I stil can't connect. I see the device in Home App, but after putting in PIN nothing happens and I don't see any info in logs.

[brutella]

Have you tried to disconnect your iOS device from your local WiFi and then connect it again.
It looks like a dns issue.

[marf85]

OK, yes, disconnecting from WiFi and connecting again , alongside rpi reboot fixed the issue with connecting to hkcam from Home app.

It's connected now, it appears in Home app, but there is no video stream.

And this is what I get in logs :

How much memory did you assign to the GPU?

[marf85]

I've reinstalled Raspbian on SD card and it worked. You were correct about issue being in my network. Thank you for help.
