    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.

                Most likely it is a permissions issue, can you open a webterminal into the app and check the group ownership of the node?

                ls -l /dev/<yourdevice>

                    chmod 777 resolved the problem but not sure it's a good idea lol

                      Probably don't need the 'x' bit on devices. So 666 maybe.

                        ah good next package release will add the cloudron user to the dialout group, that should fix it also in the long run then.

                            oh indeed, the change didn't make it. Will include it with next release then

                                Just did another test install and at least my ttyUSB0 device would show up correctly with:

                                > ls -l /dev/tty*
                                crw-rw-rw- 1 root root      5, 0 Feb 16 12:18 /dev/tty
                                crw-rw-rw- 1 root dialout 188, 0 Feb 16 12:18 /dev/ttyUSB0
                                

                                So in your case you still had to add read-write access to the group for your device?

                                  Yep, as you can see, /dev/ttyACM0 has no right for group :

                                    actually the group permissions are rw only others have no access. So this looks correct to me.

                                      but it didn't works 😕 I had to chmod again, is there any solution to launch a script at startup ? I don't want to chmod every time the app is updated

                                        So to be on the same page, if you give read/write permissions to all users HomeAssistant can use the device fine, but not if only root and dialout group have it? Reason I ask is, since HomeAssistant as such runs with the dialout group. Which kind of integration is this? Maybe it spawns other processes which run as different user?

                                        Since I can't reproduce this locally, maybe you can send a mail to support@cloudron.io if you want us to take a direct look at your case to get this fixed.

                                          Yep it does work only if i perform a chmod 666. If you can't give read/write permissions to all users by default, is it possible to launch a script at launch automatically ?
