New user questions - registration, and Sonos speakers

Choices in Zigbee are slim right now. There’s a new Zigbee 3.0 six button unit from Aqara Opple that I’m using, but it has issues when directly paired to HE at the moment. People with development skills in the community are working on that. Mine is joined via an Aqara hub and synced back through HomeKit/Homebridge.

Have a look at the Remotec ZRC -90 Z-Wave controller.
