Nah, that’s just a clue

I’d be curious to see what system resources are required for Alexa

I could see that, but you have to remember that the average consumer doesn’t have an automation hub or get deep into the automation sphere, and as such many of these products are designed to be standalone devices that can be controlled from a phone. Often enough they can be the only ‘smart’ device in a home.

That all said, a dumb thermostat like your suggesting would still require a small CPU, ram, embedded OS, and network stack/hardware to operate and communicate, so I don’t know how far the savings would go. I can’t imagine the processing power on something like a nest is that powerful as it is.

Yes, the C/blue wire is common, basically a neutral for the 24v system and necessary for more digital thermostats to keep the thermostat powered (some can work without the c wire, but it depends on the unit feeding power). The old mechanical ones work on the tilting mercury thing or copper coil for temp sensing, and only require the red wire to touch their respective wires to call whatever function, but the digital ones do the same thing on a switching level. I know there are additional wire sometimes for multistage heat and zoning, but as far as I know it’s the same principle. I’ll be honest I’m an electrician by trade and not an HVAC guy, and I know some of the more intricate systems can deviate from this, but your average residential system should be similar or damn near the same as my original comment (granted my experience is in Southern CA, so there are possibly regional differences with oil furnaces, radiator systems, etc).

Heat pumps are an entirely different story, and I don’t have too much experience with them, most of the splits I’ve seen come with their own remote controls. I was talking on more traditional wall heaters, central air/furnace/forced air, etc.

Thermostats are Barney basic in function, touch the red to the hot to call heat, red to yellow for cool, and red to green for the fan, then open the circuit when the temp is where you want it. Kinda sounds like a fun project.

This is what we get when politicians write technical laws without asking experts how it actually would work in practice and possible ramifications.

Not just him. Trump has the most billionaire-packed administration in history, and they are all about to see huge gains.

Is Japan facing the brutal cost of living situation as other developed countries?

It’s pretty bad. I’m having to back out of the stream every few minutes. Maybe Netflix should stay in their lane.

And for the record, I’m watching on a hardwired Nvidia Shield with a 1 gig fiber connection with nothing else running.

“…The people can not be all, and always, well informed. The part which is wrong will be discontented in proportion to the importance of the facts they misconceive. If they remain quiet under such misconceptions it is a lethargy, the forerunner of death to the public liberty. We have had 13. states independant 11. years. There has been one rebellion. That comes to one rebellion in a century and a half for each state. What country before ever existed a century and half without a rebellion? And what country can preserve it’s liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants. It is it’s natural manure. Our Convention has been too much impressed by the insurrection of Massachusets: and in the spur of the moment they are setting up a kite to keep the hen yard in order. I hope in god this article will be rectified before the new constitution is accepted.”

I remember seeing something years ago that it was to essentially force people to go wireless, as that was their aesthetic and what they wanted people to see when watching others using a Mac.
