Cool, I'm going to follow your posts about NAS/docker configuration, because I have been considering moving to docker from my nodejs installation on a vanilla Raspberry Pi OS installation.
In case it is useful to anyone else, I just posted by Sonos node-sonos-http-api drivers here and added them to my HPM repo.
These drivers give a lightweight abstraction of grouping/ungrouping and album or track art for display on dashboards. They also give the ability to create custom commands for the node-sonos-http-api and expose them through numbered button pushes. I found this easier than assembling a bunch of HTTP queries in RM rules and other virtual devices.
