Home Assistant repository to run Spoolman as an addon
Use the following link to add the repository:
Alternatively go to the Add-On Store, Click the three dots, then Repositories, and then add the following:
https://github.com/gschmidl/hassio-spoolman
You'll need to execute the following in a HA console to create the storage directory. Sorry, I don't know how to do it automatically and all inquiries remained unanswered.
mkdir -p /config/addons_config/spoolman
chown 1000:1000 /config/addons_config/spoolman
