Finally got Home Assistant Green and solved the volume control

I've been messing around with the home assistant for a few years in tiny slices of effort with no real outcome. For reasons not relevant to this note, I got a WiiM input for a receiver in my Apple Home setup but was frustrated in lack of convenient control over which streaming station, etc. I went back to my ChatGPT assistant and then decided to buy the HA Green. Within a couple hours I got the Philips Hue tap dial switch set up to play 3 different streaming stations and with volume control via rotating the ring.

I'm sure this community is leagues ahead of me, but I'm really satisfied that it 1. worked, 2. was not hard.
