I have 4 zone heating in my house.

The basement, where the server is, and sunroom are connected by a door I leave open. The server keeps it all at about 16 degrees with no heating on in those zones when its -4 degrees outside. I love it because I can pretend its free heating.

You dont like mesh?

I personally use it for phones, laptops, and tablets and its not bad at all. Even have signal out to my backyard.

I do get backhaul is better but mesh isnt too bad.

Disclaimer: anything that can be hard wired in my house is hardwired, mesh is only for things without a lan port.
