Honestly, my opinion is that I don’t see the draw of matter/thread. I started with z-wave, added ziggby to be able to use the fan canopy modules, and just recently added a matter/thread door lock. They all work, but I honestly don’t see any reason to go with matter/thread over the others.
Sure matter may be the future at some point, but from what I’ve seen it isn’t here yet, so why would I switch? I have zigbee capability, I have z-wave capability, and those aren’t going anywhere anytime soon, so I’m perfectly happy to continue using those - including with new devices - until such a time as I can only get matter devices. Perhaps at some point I’ll have more matter devices than zigbee/zwave, but I don’t imagine it will be any time soon.
