For anyone following the Hubitat driver side of this discussion, I’ve now released a new community driver package specifically for the VTM31-SN:
It includes comprehensive configuration support, an independently controllable RGB notification-bar child device, built-in effects, button and multi-tap events, and power and energy monitoring. The release post also documents the remaining Hubitat Matter limitation affecting timely delivery of some button events and links to the related platform request and technical discussion concerning Matter’s IsUrgent event-delivery mechanism.
Feedback and real-world testing are very welcome.
Cheers!
