Ikea turnable dimmer for vol+/- Sonos?

I agree that mostly less gateway is better. However, consider that the Tradfri hub is local only, and it also has an Homey app to control all the bulbs/dimmers/outlets you add in the hub. And also you can use the dimmers and the mentioned SYMFONISK remote. In my experience it also has better zigbee reach than Homey itself. That being said, I like it better for now, maybe when Homey finally rewrites Zigbee I will go back to Homey also my single controller
