Absolutely wrong. I have dozens of devices integrated, from a lot of brands, all working. You can of course try to get a turnkey solution from like Loxone, but be prepared to pay thousands of dollars, and good luck adding anything that’s not in their ecosystem. And there’s a lot of that. And what is there is all pretty outdated.

Xiaomi is great and I use a lot of their stuff, but the options for automation are severely limited.
