Thanks for the kind words. To be clear, of course, this doesn't eliminate the need to keep your SmartThings hub running, but quite the opposite! HubiThings Replica just allows you to mirror SmartThings' devices to Hubitat, and this driver simply leverages that capability for Sonos. My part in creating this driver is tiny compared to the work that @Bloodtick_Jones put in to creating HubiThings. My work rests upon the foundation he created.
They wouldn't be able to use anything from my driver. A entirely new websockets driver is what's really needed, IMO.
