Ikea made a rotary encoder (dimmer) like that with Zigbee. It works well with Home Assistant. It actually had an accelerometer to determine its position, so it could be rotated within a passive magnetic mount. Unfortunately they stopped making them. They replaced it with a square one that doubled as an on/off button. But perhaps you can still find some second-hand. It was in their Tradfri range.

I have about 5 or 6 of those square on/off ZigBee switches. They're perfect for automating through Home Assistant.

Now I just have to find those encoders you're talking about. It's exactly what I wanted to buy.

Yeah they were pretty great but DeCONZ didn't support them. Which just happened to be the stack I chose.

Apparently they were supported through the HA integration but not in the GUI. They also work with ZHA as far as I know.

I still see some on Ebay, not sure if they can be shipped to Europe though: https://www.ebay.com/itm/133779313546?hash=item1f25de538a:g:... . This tends to be an issue.
