All of this can be done with ZigBee. It is open and local mesh over 2.4ghz.
You need to buy the zigbee adapter. With matter you can use just regular wifi cards
I know because that’s what I have been doing for the past five years.
But to be fair my setup is now mostly IKEA so I guess I could go back to a bridge and stop having to maintain my stuff at some point.
Meet zigbee2mqtt and ZHA. You only need a cheap USB adapter as a Zigbee coordinator and you are ready to go.
Any reason you prefer Matter rather than Zigbee? Zigbee has been a thing far longer than Matter, so I don't think the "one more standard" criticism is valid here.
(Unless there's some new feature you're really looking forward to. But I'm not aware of many of them.)
