Sleeping with heating on seems a waste of energy to me. At least in Spain.

I have a dumb thermostat. It doesn't even have a clock. It just has two buttons, one two increase temperature, the other to decrease it. In winter, during the day, I put it at 20C. At night, I put it at 15C or lower (which stops heating, as the house temperature decreases to about 17 or 18 degrees during the night, without heating). It works like a charm. We are not cold at night as we use pyjamas and duvet. We also have a baby. In fact, if I forget to turn off the heating at night, I can't sleep well and I often get up to turn it off.

Almost all US central heat and air systems are "forced air" -- gas or electric heaters (furnaces) that blow conditioned air through ducting. Boiler-radiator systems wouldn't work with the standard US thermostat, not least because US thermostats use low-voltage signaling.

You must be from a warm part of the U.S. Forced hot water systems are very common in the colder parts, and they use the same thermostat wiring as forced air. Some parts of the U.S. even use diesel fuel for heat (it's called #2 heating oil, but it's really just diesel fuel with pink dye added so they can fine you for using it as a vehicle fuel...it's taxed advantageously). Also, boiler-radiator systems can absolutely…

It still is popular, even in new construction, in the Pacific Northwest.

I sleep with all windows open even in -20 C. You get really refreshed, you sleep much deeper and you learn to ignore all street noise.

Because when you forget to change the setting to heat and wake up to a 60 degree house you rush around hoping the pipes didn't freeze. Or when you set the AC to 70 because you were warm and leave to go to work and forget to set it back.

If your house is 60 degrees. It didn't freeze.

If it's 60 degrees then it isn't freezing now, but it could have been lower overnight.

I looked into this, but I quickly realised I never use my Thermostat.

My heating is controlled by a time-switch that directly enables the boiler in the morning and at night, and as far as I know this is how most people I know operate.

We do have thermostats but they are largely ignored boxes that sit in the hallway and/or landing.

Is this just something to do with living in a cold country? I would have thought a nest equivalent that directly operates the boiler would have been a better device ...

Sounds like you have a water-pipe central heating system. You probably have thermostatic valves on each radiator, which control the flow to each radiator.

That's why the main thermostat doesn't do much.

Yep exactly! It's pretty much standard here. So I guess the Nest is targeting people with electric heating only? Sounds like taking a "quick win" while ignoring a potentially larger market!

Why not (and i realise that this is a dirty horrible hack) isolate those devices to their own dedicated virtual ap and isolated network. that way you get to restrict what they can talk to, what can talk to them and the keys that everyone else uses. this also allows you to finally get around to rolling out eap so the scourge of shared wifi keys can die out :)

EAP-TLS ideally. You need a CA infrastructure, a radius server, and a way of doing automated enrolment, revocation and install of client certificates. A lot of work if you haven't already got those parts (though many places already do), but it's fairly hassle free and secure once up and running.

For bonus points you can extend 802.11x goodness to your wired desktop ports as well.

You probably need at least one other network/BSSID with standard wpa2 for non-managed devices as you say.
