Absolutely. I wouldn’t have expected anything.
And I’m good at finding exactly what I’m missing in a great new feature set.

For example:
How cool would it be to have a UX like #nodeRed to manage all your automation? And JavaScript automation blocks.

So what about these Ikea scroll wheel remotes? They send 16 button press events for a complete turn, so we simply change brightness a bit for each step.

When turned fast, the send multipress events which need to be handled and to make them scroll smoothly the transition times for brightness changes need to be tuned right.

So smooth and efficient dimming with matter is as easy as connecting to matter-server's WS, listening to remote events and emitting Move events. 👀

Interacting with z2m over mqtt was easy, but how to do the same with matter?

Homeassistant uses matterjs-server (or it's older python variant) and they both expose a websocket for clients to receive events and send commands directly to matter devices. That's how Homeassistant connects to matter-server too.

You can expose matter-server's websocket on the network.

The two green remotes are new Ikea Matter remotes. The left one with the scroll wheel works completely different, but for the dual button remote we have the same problem as with zigbee: Homeassistant has no way of making this work smoothly.

Should it be possible though? Yes. Matter lamps have a 'Move' command and even a 'MoveWithOnOff' command with slightly different behaviour. Both work fine on the Ikea Matter bulbs.

For ZHA users, the usual recommendation is to directly bind remotes to lamps which enabled smooth dimming.

#zigbee2mqtt allows sending the brightness_move command to zigbee lights, which allows to start/stop very smooth dimming with minimal traffic on the mesh.

Because Homeassistant has no sensible way to use this, I created a crazy #nodered flow that directly works with zigbee2mqtt to make my remotes work they way they should on light groups.
