In my experience, Matter already works better than Zigbee and Z-Wave ever did, and it gets better every year. I'm interested in what your unusable mess of a system consists of, if you don't mind elaborating.
> It is recommended to run the Matter add-on on Home Assistant OS. This is currently the only supported option. Other installation types are without support and at your own risk.
So I can't even officially use this stuff without uprooting my entire operating system.
To be fair, step 4 isn't a real step, step 1 is just buying the "hub" or "border router" or whatever, and step 2 & 3 are the same for Zigbee and Matter, the button is just somewhere else.
A typical consumer has bought a zigbee hub (like they need to buy a thread border router), then use their phone to press a button in the app and then they press a button on the device. Still dead simple and doesn't require flaky bluetooth from their phone, which in 2025 most androids still suffer from.
That’s been my experience. My older Zigbee/Z-Wave stuff seemed to work… up until it didn’t, and then cue wailing and gnashing of teeth. My Matter gear was initially a little flaky but is now vastly more reliable than Zigbee ever was.
