Hi community! 
I’m looking to start get HA integrated into my work life because there’s a raft of opportunities for it but my first foray is into the heating system.
We have a changing rooms/toilet block that isn’t near our main reception building where the HA pc is but has it’s own self sufficient boiler/radiators and hot water tank. It’s got a good private WiFi signal.
I’d love to be able to keep an eye on the temps in the changing rooms and change the set temp through the year remotely
I wondered if anyone had come across anything that either preferably doesn’t have a user display or is lockable because I know our lovely customers will just turn it right up every day if they see the stat.
I’ve seen the small matter temp sensors which would do a good job but don’t know if there’s a bridge that they could connect to which would wire into the boiler to trigger it at the set temp?
I’ve got a nest at home that was easy to wire in and use the wireless stat, I just need something like that but one that’s just a basic, faceless remote stat and integrates into HA.
I hope I explained that well enough!
