Perfect timing! Thanks OP - ordered!

Used to be good, used to work with HUE, Google, one of the largest if not the biggest company in the world, have made a mess of it, like they seem to do with everything, numpties.

Beware that the Heat Links that come with them notoriously fail, so much so that google are replacing them now regardless of warranty. Granted it’s free but it’s a pain when your hot water or heating fails and you have to do without until an engineer turns up and swaps it.

I’ve had two replaced now :/ (edited)

Had mine about 8 months still cant get the power monitoring / history to work. If you google it seems to be a big problem and google not bothered. Shows the data on the thermostat but always wrong in the app (edited)

This came with the new built property. Master bedroom has Google thermostat with no valve (TRV) on the radiator but other 2 rooms have.

Meaning if I turn the thermostat off, heating in other 2 rooms is cut off. Normally I don’t need heating at night but some guest’s struggle because of this

Builder said it’s how it is supposed to be (radiator doesn’t have a valve in the same room as thermostat). I think it’s a poor design. Any solution to this issue?

The best feature on this for me is the ability to put a limit on the temp setting. So for example you set the max temp to 21c but the default everyday temp to 19c that means when someone comes in and wants a bit more heat they can turn it up to 21c. BUT it will stay up until the next setting block comes in. So that could be 11pm and someone turns it up at 1pm and goes back out for the rest of the day.

SO you have to set the 19c temp every hour so there will be 10 x 1 hr blocks between 1pm and 11pm. Then when someone ups the temp to 21c it will knock back down to 19c after 1 hr. If they want more heat they have to get off their backsides, or if they go out it's not wasting energy all day. I pay the bills I set the rules and I have the PIN number.
