Alright - I admit - I made a dumb mistake. I am posting this solely because when I looked I couldn’t find the answer I was looking for (which was simple). Maybe this will help someone else.
I run HA on an Ubuntu PC insider a Docker container, and use Docker Compose. I recently purchased a Nortek Gocontrol HUSBZB-1 stick to add a zigbee and z-wave networks to my HA. But like many people, I could not get HA to find the zigbee stick. There are lots of pages out there with sample docker-compose files for this scenario. I tried them, restarted my pc, but no matter what I did HA could not find the USB stick.
Finally, it dawned on me: maybe instead of restarting my PC, I needed to rebuild my docker container. I tried that and … Presto! No problem. All works. For anyone who is interested, Here is the docker-compose file that worked:
version: '3' services: homeassistant: container_name: home-assistant image: homeassistant/home-assistant:stable volumes: - /hass/config:/config - /etc/localtime:/etc/localtime:ro - /dev/serial/by-id:/dev/serial/by-id devices: - /dev/ttyUSB0:/dev/ttyUSB0 - /dev/ttyUSB1:/dev/ttyUSB1 environment: - TZ=America/Los_Angeles restart: always network_mode: host
After saving that file, I ran the following (which updates HA and rebuilds);
sudo docker-compose pull sudo docker-compose up -d --build homeassistant
Hope that helps someone else.
