I have these panel heaters in my home office that I have to manually turn on, thinking it would be great if I could connect them to ST so I can regulate the temperature in the room automatically. I might need an electrician for this but is it possible and what tech do I need?
I had one of those that had a plug on it and I just put a Z-Wave outlet adapter inline. What is that wire going into? Is that a standard outlet box with a switch?
As I said before, I know nothing about electricity requirements in UK, but something like this (if it works in UK and can handle the current the heater panel draws) might allow you to do what you want.
