That is exactly how it works. They aren’t ‘sub-containers’ though. They are just normal Docker containers.
The script merely downloads the appropriate container for your architecture, and creates the systemd service to kick off the container on startup, as well as mapping through some directories.
You can’t actually do this at this time. HASSOS does not have a NUC install yet.
Does anyone have the Zigbee portion of the HUSBZB-1 working on an intel NUC running Hass.io? I have everything running perfectly but had to keep my zigbee devices running on Smartthings and connecting via MQTT. For some this reason, this is bugging the hell out of me even though its all running well without any delay.
