/dev/ttyUSB0 permission issues in HA container and Skyconnect

This integration worked before, but something changed. I'm guessing it's a user/group permission issue based on the logs. I would appreciate some feedback on this process while I troubleshoot. Setup: - Raspberry Pi 4 Model B Rev 1.1 - aarch64 - podman version 4.3.1 - ImageName: "ghcr.io/home-assistant/home-assistant:stable" - ImageDigest: "sha256:067490d7b65cfa8b9e494a9447b0e5a7876be83ead7ec01738681c55d66e7cfe" I created this script to be able to recreate my HA service with the latest container image: ``` #!/bin/bash # Variables and env PODMAN_NAME=home-assistant loginctl enable-linger $USER export XDG_RUNTIME_DIR=/run/user/$(id -u $USER) # Cleanup systemctl --user stop container-${PODMAN_NAME}.service systemctl --user disable container-${PODMAN_NAME}.service podman rm -f ${PODMAN_NAME} # Pull images podman pull --arch=arm ghcr.io/home-assistant/home-assistant:stable # Create Home Assistant image podman create \ --arch arm \ --env TZ=America/New_York \ --volume=/opt/home-assistant/config:/config \ --volume=/opt/home-assistant/config/www/media:/media \ --device /dev/ttyUSB0 \ --network=host \ --restart=always \ --name ${PODMAN_NAME} \ ghcr.io/home-assistant/home-assistant:stable #--privileged \ #--annotation io.crun.keep_original_groups=1 \ # Generate user service with podman generate systemd podman generate systemd --new --files --name ${PODMAN_NAME} --restart-policy=always # Setup systemctl files correctly mkdir -p ~/.config/sysetmd/user mv container-${PODMAN_NAME}.service ~/.config/systemd/user/. # Enable the service systemctl --user enable container-${PODMAN_NAME}.service # Start the service systemctl --user start container-${PODMAN_NAME}.service ``` Recently my Zigbee integration stopped working. I'm certain it has to do with groups/user permissions for the container and the mounted usb device. here are the logs. ``` 2023-10-04 01:19:38.443 ERROR (MainThread) [zigpy.application] Couldn't start

others, but i don't think it behaves the same in podman as it does in docker. I've also added the home-assistant user to the dialout group based on another post but still the zigbee integration fails to load. Any hints on where to look next?

hello world!

This weekend I had the urge to use my raspberry pi! Podman + the all in one image and I'm up and running. (Ok it wasn't quick as I played with different Debian releases and getting the podman systemctl process working) So far, I am most excited about being able to track the humidity on my nest thermostat. I'm in Miami and am in a constant battle with it! I'm playing with the cards and really like the gauge and statistic views. Connected my pi-hole, my Spotify, weather, lights. Trying to figure out what's next. Recommendations welcome. Happy to see the community support as I read more.
