Unable to get ttyUSB* devices available in Home Assistant container about iotstack HOT 4 CLOSED

Regarding #49, because the correct version of hassio works through its own service it is no longer operated through the stack. Be sure to remove the 'hassio' service from your docker-compose.yml file.

I haven't tested adding USB devices on the fixed version. I do think that it's own service should add support for usb.

If you can please install the corrected version and report back on whether the USB works as expected

After some further experimenting yesterday, removing the home-assistant docker image (the previous non-hassio version) and pulling a new instance the ttyUSB devices became visible, so got this working with the 'old situation'. Before, I had restarted the stack and rebooted the host several times but that did not help getting the ttyUSB devices available, but pulling a new image did. I cannot explain why that helped.

After that I installed the new hassio via the updated IOTstack menu (and removed the old Home Assistant image).

In a console session to the new hassio "homeassistant" container I can see that /dev/ttyUSB0 and /dev/ttyUSB1 are visible without having to do any additional configuration.

Docker unfortunately does not handle symbolic links to devices (defined using udev rules) so from now I will use /dev/serial/by-id/... to always configure the correct USB/serial device.

Any idea how to restore a Home Assistant configuration in hassio (which does not use IOTstack's ./volumes directory in the host for storing configuration files)?

In the little testing that is did is did see that the preferred method of doing backups for hassio is to use the built-in system snapshots. That should be stored in ls /usr/share/hassio/backup/.

I want to test making a symbolic link to that directory and possibly the the homeassistant directory as well into the IOTstack/backups directory. That way i could integrate the backups together. If memory serves tar requires additional parameters to follow symbolic links.

Thanks for the heads up on the USB/Serial. This topic is going to come up in the future

Added hassio backup to todo list
