A $3.2 billion* thermostat....

Chilling. Literally chilling.

There are net connected sex toys, usually a vibrator or some other unmentionable synchronized with something having to do with some other unmentionable activity taking place on the screen, solo or group, etc...and, no, don't ask me for a link.

That's not quite true, no matter how advanced the HVAC, it will always be c ompatible with a standard TSTAT. It may want more sensor input, like humidi ty, and outdoor temperature, but they will always keep it compatible with a dumb TSTAT. All the advanced system control is taken care of by the HVAC i tself.

They're already in the intrusion business, so they're half way there! Jamie

It will send data back to google to be analyzed and sold.

it!

Down the road: Google goes into the home fire and intrusion alarm business.

thermostat failed. (on some cold winter night of course.) There was an old mercury switch on bimetalic strip thermostat in the garage. Same round foot print. I installed it and it's been there ever since. I'm such a luddite.

thermostat that can work with three-phase heater (each phase 1.5kW)? I can not find thermostat with PID and three phase thyristor controller.

Real simple, just add a contactor. I have done that before.

No. I need smooth phase control. Not just on/off.

And I need PID regulator. I'm use a "heat floor". It's have a huge thermal inertia.

That would be straightforward move (perhaps getting the alarm monitoring companies to subsidize the costs). The intrusion alarm is a bit more interesting because it will require a lot of sensors, which could be quite a bit smarter than the current on/off switches, incidentally gathering all sorts of data. You could also sell features that would involve tracking people (such as the cell phones of your kids to tell you when they come home or leave). That would, of course, mean the capability to track everyone would be there.

This will also help Google vacuum up the few WiFi passwords that it does not already know.

Is this an industrial application? If so, there are plenty of COTS solutions that will work beautifully, but they'll not be in the consumer price range, nor packaged for consumer applications.

No. It's for my home heating.

I will not do it neither on PLC or self-made controller.

Talking of thermostats, here is mine - did it within an hour or so a few winters ago when the oven's in-built one died in the middle of some holidays and under a lot of snow, 10+km from town:

:D :D

I believe I even remember where I drew something like a circuit for it (on paper, that is perhaps the only "circuit" I have done on paper last few decades :D ). Used an LMC6482, an AD592 temp sensor, the helipot was initially even calibrated for temp - until a few years later one of the two trimpots inside drifted and I turned both blindly, not remembering which was which (hysteresis and calibration). It is still in use, burned a number of relays (I used to mount the relay inside the oven, lately I adapted a mains extender....). Anyone with the billions for my proud design? No? Oh what a shame, such an avant-garde device on offer and they go for that stupid round knob.

It's not about your thermostat. It's about giving google access to your remote devices so they can monetize the information. Today, it's your thermostat. Tomorrow, your fridge and your toaster and your blow-up girlfriend...

Hmmm, OK, I get that. Let us even assume they want to be snooping every breath you take just for their commercial purposes (LOL, that's not an easy one to believe). But where do the 3.2 *billion* dollars paid for a *thermostat* company come into it.

Nest have patents, it was bought to get firepower to keep patent trolls and competitors away

same reason Google bought Motorola after Apple, MS etc. started to sue them over cellphone tech

These are commonplace. Look on Omega.com under furnace controllers.

Ah, patents. So these Nest have about 1/3 worth the patents Motorola had. Just out of the blue, at the snap of their fingers... What do we know.

The whole thing is ridiculous. What is it about I don't know - money laundering, a way to pay someone for some services which are not to be made public, you name it - but it certainly is not about what they state it is.

On/off is a much better way in that case. Long time constant smooths out the pulsed power. The trick with a domestic situation is to make sure the time proportioning doesn't cause the lights to flicker noticably.

I don't see why a simple $20 thermostat won't work with a suitable switching device. Baseboard heater thermostats might be able to work directly.

It has nothing to do with producing a useful product, anyone can see from t he product engineering specs, appearance, and "app"-centric operation that it's an over-hyped gadget designed for the gadget oriented idiots who throw money away on overpriced Apple products. I wouldn't turn over the operatio n of an expensive HVAC system to anyone less than Honeywell, only an idiot would patronize these bit-head hackers from California, it's obvious they d on't know jack about the machinery operation they claim to optimize, but th is is U.S. where wealth is usually generated by duping ignorant imbeciles.
