The solution is home assistant [0] it lets you manage and control all kinds of smart devices with a lot of customizable, hackable things. And it runs locally, so if you buy the right types of devices that don’t phone home to the cloud (or you shitcan their internet access) you can fully manage your own system.

Or if you want something more of an appliance, some other Hubs with Zigbee, Z-Wave, and Thread + Matter support are: Homey Pro, Homey Bridge, Aeotec SmartThings Hub, and Hubitat.

I only have experience with the first three (besides Home Assistant) and they work very well (though the SmartThings hub is somewhat limited when it comes to device support, graphing, etc.).

I should also mention that with Homey Bridge the dashboard is in their cloud, though the Zigbee/Z-Wave devices are fully local. Homey Pro is also local. (I think they have a Homey Pro Mini in the US now.)

Imho Home Assistant is the way to go - there's just so much weirdness going on in a regular home you need to accomodate that with any of these 'turnkey' solutions, you'll run into some limitation that you can't get around.

HA is fiddly but with enough effort you can make anything run the way you want to, and the community is pretty active.

So these things are phoning home. The exact opposite of why Home Assistant is existing.
