Hey there @dmulcahey, @Adminiuga, mind taking a look at this issue as its been labeled with an integration (zha) you are listed as a codeowner for? Thanks!
_{^{(message by CodeOwnersMention)}}

Adminiuga · 2021-05-08T13:03:09Z

There's no serial port device file. Zha does not create that file, so the problem is not caused by zha. Check what creates that file (udev), afaik there were reports of udev breaking in the update?

But this is not issue caused by zha

Adminiuga · 2021-05-08T13:08:13Z

Also, try re-plugging the conbee

jcallaghan · 2021-05-08T13:20:33Z

Thanks, @Adminiuga. No change when removing and adding the stick. I've reverted to 2021.04.6 as I'm quite dependant on ZHA running particularly with this many devices 🙃

Adminiuga · 2021-05-08T13:23:58Z

Is it home-assistant core? Or docker?
Core on Python venv doesn't do any low level device management and just update shouldn't cause the device to disappear

jcallaghan · 2021-05-08T13:43:55Z

Apologies yes running in Docker.

davet2001 · 2021-05-08T14:45:59Z

I had the same issue. /dev/serial is not present in the docker container for me, even though it's present in the host OS and in the portainer config file.

Adminiuga · 2021-05-08T14:54:31Z

New docker images are not running udev daemon anymore? Check the release notes for the docker images

davet2001 · 2021-05-08T16:54:02Z

Maybe this is related?
home-assistant/docker#180

Adminiuga · 2021-05-08T16:59:33Z

Pretty sure it should fix the problem

davet2001 · 2021-05-08T17:56:45Z

Pretty sure it should fix the problem

I was thinking that PR might have introduced the problem.

jendib · 2021-05-08T20:55:43Z

How are we supposed to map USB devices like ConBee now? (I'm using the Supervised version)

Adminiuga · 2021-05-08T21:01:16Z

Yes, you are right. That's the breaking change from the release notes https://www.home-assistant.io/blog/2021/05/05/release-20215/#breaking-change

Set the environment variable to enable old behavior. Optionally provide feedback in the docker repo, as the maintainers would like to know how that is being used.

Personally, I'm not fond of running privileged docker, so the options are:

pass through the device -- but docker doesn't handle hot plugging
mount the dev folder and use control groups for character devices

ATM i did the later.

Adminiuga · 2021-05-08T21:02:54Z

The issue is caused by the breaking change home-assistant/docker#180

Setting the environment variable should enable olde behavior.
Closing, as this is not a zha issue.

davet2001 · 2021-05-08T21:57:19Z

I tried adding

    environment:
     - USING_UDEV=1

To the end of my stack configuration file. The re-updated the stack. But still no different

bash-5.0# ls /dev/serial
ls: /dev/serial: No such file or directory
bash-5.0#

All ZHA devices are offline, and I can see /dev/ttyUSB0 etc, but I don't see any way to reconfigure the usb stick to use a different path without deleting the integration. Presumably I have to re-add all devices if I do that.

Adminiuga · 2021-05-08T22:00:41Z

You could carefully edit .storage/core.config_entries file but removing and adding integration is safer way. But may loose some customizations, haven't tried this in a while

Thanks, editing .storage/core.config_entries worked. Feels like a bit of a hack! For anyone trying to repeat I did:

Stop the container.
In the host machine terminal run ls -laR /dev/serial to list which physical USB devices the symlinks are mapped to.
Make sure that your docker config file maps any usb devices you want to use into the container, e.g.

...
  devices:
    - /dev/ttyUSB0:/dev/ttyUSB0
    - /dev/ttyUSB1:/dev/ttyUSB1

Edit .homeassistant/.storage/core.config_entries, replacing /dev/serial/by-id/xxxxxyyyyy with the device mapped above e.g. /dev/ttyUSB0
Don't edit anything else!
Save and close.
Start the container.

Now zigbee devices all work again.
