Thread and matter are a mess from both technical and consumer angles. Yes, they are both good technologies...but the players in the hub space have made an utter mess of it if you have multiple hubs or, like most Americans, use an iPhone but have Nest or Echo devices. Then you have the lack of adoption of thread in general. And finally, Matter support being always 6 months away for everything or just straight up not working. It is mind blowing to me that it was easier for me to set up my Wiz bulbs to work in Homekit via HA than to get them to actually frickin work over Matter...seeing as the Matter logo was on the box when I bought them.
Honestly, I'm kinda shocked that no hub company has shipped a Cheap Zwave/Zigbee integrated HA hub. Sure you have HA Green and Yellow and all that, but you could get that price way down with a simple partnership and purpose built hardware that is elegant.
