This bridge is trying to get Mastodon and BlueSky to exchange information... https://techcrunch.com/2024/02/14/bluesky-and-mastodon-users-are-having-a-fight-that-could-shape-the-next-generation-of-social-media/

I don't have a master device as all. The house is from the 70's, and all our radiators were only manually adjustable valves (turn from 0 to 5). The wireless system just replaced having to hand-turn every radiator on and off daily. No master device was present at all.

Well, it doesn't have one, I'm currently using Honeywell devices which communicate wirelessly.

That seems to be it. Thanks. Too bad that doesn't seem usable without extensive wiring and is thus only an option for newly constructed houses.
