Product Suggestion: Rotary control knob

Hey guys, it would be awesome to have a rotary control knob. Basically you can put it wherever you want in your house and control things remotely. Just like IKEA Symfonisk, but not just for volume.

I managed to get the one above working with Home Assistant, it’s Zigbee and it’s pretty amazing just a bit laggy. It would be awesome to get something like this for the Zwave network.
