I have an Apple TV 4K (2021) as my main hub, a number of iDevices switches, Leviton switches, Yulight and Meross light bulbs, a Hoobs system with bridges powering Nest thermostats, a Samsung mini-split (with Sensibo) and a Ring system (with sensors and cameras), all operating with no apparent issues; at least none I can tell vs. before I switched over to the new architecture.
