external devices - zigbee

[eyecreate]

I was playing around with homeassistant to see of I could use this server app instead of my RPI. It seems I can't find a way to pass in devices like my USB ZigBee radio to the container. Is there a workaround or plan to make this possible?

This is currently not supported on Cloudron. We need to implement this on the platform side. I am also in need to bind /dev/ttyUSB0 into my instance. Wondering what the best way to implement is. Which device would it be in your case?

I've been using this device:
https://slae.sh/projects/cc2652/
As well as a development device with a Texas Instruments CC2531 chip for testing.

Thanks for the link. From https://slae.sh/projects/cc2652/#homeassistant-hassio this seems to be quite specific with various caveats for the /dev nodes to use. Looks like unfortunately we have to implement something which allows a very technical and lowlevel approach then....

How could it be implemented ? Via the app settings in cloudron with a section where we could choose what usb device(s) the app can access ?

[nebulon]

Yes I think that would be the idea, maybe a free flow text input which binds the mentioned device(s) into the container. Similar to what we do for vaapi device access https://git.cloudron.io/platform/box/-/blob/master/src/docker.js?ref_type=heads#L409

If it's, for now, specific to Home Assistant app, why not just use workarounds like https://community.home-assistant.io/t/home-assistant-in-docker-pass-usb-device-from-host/184674/2 or https://community.home-assistant.io/t/home-assistant-in-docker-pass-usb-device-from-host/184674/6 ?

Alright, we have added initial basic support for attaching devices from the host to the container. For the moment this will just be a list of devices with a 1to1 mapping. So for example /dev/ttyUSB0 from the host can then be mapped to /dev/ttyUSB0 within the container.

nice ! when will we be able to test this feature on home assistant ?

@rjousse18 8.2 is in unstable. if you update to the unstable, you can test it out - https://docs.cloudron.io/apps/#devices
