Welcome to openHAB.
As you just joined yesterday, please get yourself familiar with the software and the forum first.
The forum is on openHAB, not on smart home technology in general.
openHAB can connect to anything. It is not a feasible approach to try to categorize, review or even document all smart tech on the market and its “openHAB compatibility level” - neither on the forum nor in the docs. That’s way too much to cover, let alone the huge efforts it would take to keep that up to date. Hardware can be discussed insofar it is about connecting it to your openHAB instance.
We have a Hardware category for that.
We have a Tutorials & Examples section where you can leave reviews.
And we have a search function.
But what you are looking for is not feasible, and it is outside of this forum’s scope.
Sorry for setting expectations straight in the first place, but this has been asked and discussed a number of times and repeating that discussion doesn’t get us anywhere.
