Hi all,

I'm new to the forum but fairly established with home automation, lighting done and now moving on to heating. I use homeseer and although expensive I find it great. I intend on using Oregon temperature sensors in each room communicating with my rfxcom transmitter/receiver, I will be able to switch my central heating on and off via a relay on an io board. However what I really want to do is to be able to set my radiator valves open or closed in each room, I have looked at the wireless option and have decided not to go down that route as I want homeseer integration. What would be great if possible is powered replacement trv heads which I could also switch via relays, what I don't want to is to start hacking into my heating pipe work. Does anyone know of any thing like this that I could retrofit myself, preferably not too ugly as there is the WAF to consider!

Looking forward to your suggestions or critiques of my plans!
