The signals are flawless and continue to work even if there are otherwise problems with my raspi. ClearConnect (the wireless protocol) has its own spectrum and doesn’t interfere with anything else in my house that I have found, which sets it apart from all other wireless switch ecosystems that I know of. There is a wide range of dimmers for all types of loads (even very small led loads and fan loads) and physical remote controls. The pylutron library that homeassistant uses is solid - there’s room for improvement, but that just makes it more interesting from a hobby perspective. I also like that there’s no visual difference between wireless and “normal” maestro switches, so everything will look consistent even if you don’t go all in on wireless.
It took a few hours of my life to get certified and access the configuration software for radiora2, but I think it was worth it.
Lutron doesn’t pay me :) I’ve just found it to be a great platform to hack on. It is expensive but it’s a bit cheaper second hand.
