Smart/WiFi controlled Radiator Valves... self-build controller?

But room-by-room control isn't new. Back in the early 70s, one of our neighbours had his new-build fitted out with a room stat in every room controlling a 2 port zone valve for that room. I can only assume that some later owner ripped all that "complicated nonsense" out.

I did look at that idea, with a micro switch in every valve it is relativity simple to wire so if any valve opens then boiler fires up. However back in the 70's motorised valves were expensive, and of course it would take a lot of wiring, plus you need some where to mount the valves, the wifi eTRV is around same price as a motorised valve, however it is easy to mount, and does not require cables, however the installing of software and selecting ITTT apps I found daunting, it would have been easier to hard wire.

If you really want full control over everything I have found the best way is to use Indigomatics software to control it all. They support pretty much everything you're likely to install and it doesn't need t'interweb to be on to run it. Let me know if you need more info. I dont work for them, but have been using it for a year now.
