            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 ?

                        To reactivate that thread, as a fallback for now you can add a custom cron job to chmod this device https://docs.cloudron.io/apps/#cron however ideally we can figure out why HomeAssistant can't access it otherwise. At least the USB device I have works fine that way. Maybe the integration for the device you are using behaves differently? Which device and integration is this?

                            Cloudron's cron has a special @service pattern to run once on startup
