Anyone got one and what do you think?
Have an opportunity where one might drop straight in to a relative's system and improve matters (they have odd but mostly regular occupation times and hate manually programming timers, which would make a 24/7 programmer a liability for them).
The wiring at the wall thermostat is fortuitous (ie there's a live, neutral and demand wire) which makes the NEST back end box a straight drop in. The fancy dial bit can be mounted in a more optimum place in the living room.
