Inovelli has been working on a Zigbee and Z-Wave button controller for more than 2 years now and neither of those have even entered the beta phase. In fact, the first attempt was started in 2020 and then was not completed (and since superseded by the other two projects linked).
I don’t work for Inovelli, but I would be shocked if they wanted to start a Matter/Thread switch without getting either of those closer to delivery. This is a hard problem to do correctly.
