I've used these for the last year or so on my blinds. They work over Bluetooth so one at a time can be controlled despite them being in a home assistant group. This means if I close both of them, I watch one close first and then the other shortly after. Maybe another Bluetooth radio would work? Not sure. But I like the product itself because there is no other ecosystem and it's all local. Also solar powered so no cables running everywhere :-).

There's a bunch of things you can add to normal blinds to make them smart, the problem you'll face is that most of them are battery powered.

I grabbed one of these and attached to our largest blinds and they work phenomenally. The main issue is cost, but I really just wanted something as a proof of "how" to do it, and hope to come up with a cheaper homebrew later on.

I also looked for that sort of thing recently and basically came up empty.
