I ordered a Home Assistant Green with Skyconnect. I have some Matter devices that I wanted to connect. But I won't get the Skyconnect until a few weeks later I think.
So is the HA OS itself a Matter controller that I can use to pair matter devices or do I need to wait for the Skyconnect to do that?
Space heater is not a common device type so I doubt you'll get any answers regarding how quiet something is.
Looking around Amazon, Govee is the only company making smart space heaters. So just give them a shot and return it if you don't like it considering they're your only option.
