Its USP seems to be to assess the property's thermal inertia and then adjust the heating-on time to allow for it.  They are about to be acquired by Google, apparently.  Cheap at £179!  Like most other heating gadgets they claim 20%, experienced by USA users.

Also OpenTRV is not trying to estimate behaviour of every room from *one point in the house*!  B^|>
