I have a (non-automated) gas fired boiler supplying my heating. It comes on before I wake up so the house is nice and warm for me when I crawl out of bed.

I also like the bedroom to be warm at night when I go to bed, so the radiator is on in the bedroom.

What I don't like is waking up in a room that's too hot.

So is there some way of controlling the TLV on my bedroom radiator, maybe turning it down overnight? I know I could just remember to turn it down when I go to bed, but the plain fact is that I don't.
