Lowes has the Nest Learning Thermostat 1st Generation (T100577) for $198 with free shipping. Learns your schedule to keep your home a comfortable temperature without wasting energy. Can be controlled via Wi-Fi from your smartphone or laptop. Former Apple and Google engineers are involved at Nest.
When you live solar electric, you turn off anything and everything you can while you're not using it. If not, you're running an energy consuming generator to recharge your batteries, instead of free from the sun. I live quite comfortably on 3 KWH per day, most of you consume 30 KWH or more.
Keeping all manner of electrical devices running to save a few BTU's using a $200 remote thermostat is asinine.
You never have to use the PC at all w/ it. You dont need to leave the router or wifi up to allow the nest to follow the schd program. However you will loose reporting w/o a router/wifi. It does get a 24v feed off your furnace but it can run w/o that for a bit too as it has an internal/rechargeable battery. Still I sure cant keep my house warm on 3kWH a day in the winter. And seeing a daily graph of my heat usage does force me to hypermile my heat at night. 57Deg in the Midwest is COLD however BURR
ChillyCat: Did you see the episode of South Park called Smug where they were all stroking each other for driving Priusses (Priuiii?)? LOL Ya have to wonder why somebody who *knows* he has to turn everything off to succeed off the grid would denigrate something designed to help average people who want to cut their energy wasting to a minimum unless he has a need to be appreciated for his superiority. I would think he would be applauding it!?
Well, my average monthly natural gas bill over the last 12 months was $106.8133. The months of Nov. Dec, Jan, Feb, Mar, Apr average $142.51 while the other 6 months average 71.1167. Since I use NatGas for cooking, water heater, clothes dryer, I think it is fair to say the home heating usage is 142.51-71.1167= $71.39333/mo. for 6 months or $428.36 a year.
So, using the 1% number that's $4.28 a year savings. Hummmm.
Oh, did I mention that I live near Buffalo NY? Pretty cold here.
I got one of these for Christmas. It sits here still in the shrink wrap.
Generally speaking if it were a direct apples to apples comparison, same degree rise or drop from the ambient temperature, it would take nearly the same amount of energy to cool as it does to heat, so long as the heating uses a heat pump but those become more ineffective below around 40F.
Supplemental or main heating below 40F where another tech is used would make heating less efficient than conventional, modern A/C cooling. However when applied to real world situations, we aren't just considering efficiency but also the source of the energy. When the source is natural gas instead of electricity it is usually less expensive to heat than cool.
On the other hand, air conditioning also tends to remove moisture from the air which helps humans feel cooler. The average person will tend to feel more comfortable with a winter temperature 5 degrees below their ideal and wearing heavier clothing, than 5 degrees higher than their ideal temperature in summer and a higher humidity level from running the A/C less.
Lastly there is the consideration of local temperature control. You can space heat an area you'll occupy with a $20 electric heater while a single room A/C unit would cost roughly $200 or more once you factor in installation cost if you don't DIY. A window A/C is less efficient than central air but getting back to the prior ideal of people tolerating a cool environment in winter better than a warm environment in summer, the window A/C will likely save a little more than its addt'l cost by the time it is worn out.
Frankly it is easier to just petition for more nuclear power plants and to tap US shale gas and oil deposits so there is plentiful low cost energy than spend all your time calculating out every possible scenario over and over again then readjusting your thermostat to compensate. This may be a learning thermostat but it learns from you, it isn't smart enough nor does it have enough information to do that on its own.

Great leave your router and/or PC on so you can remotely control your $200 thermostat. Only in America?!?
I don't think most people turn off their routers when they leave the house.

Do you have at least one clue, as to how basic networking operates ?
I'm sorry, maybe your "country" has yet to implement LAN/WAN ?
WHY TF would I turn my router off when I leave my house?
So it doesn't run away?
@ btc909 So your kniving cat doesn't access the internets and watch kitty p0rn while you are away.

In Soviet Russia thermostat controls you!

not a problem.
BFD ! Well aren't you special. Living off solar and all.
** I'd have a bit of an issue heating 3700 sq ft off it **
Why the heII would you comment on a device, that's obviously
designed for folks.... "ON" the grid ?
Your pidly lil panels impress no one
PS: "most of you consume 30 KWH or more"
Correct, this time of the year, at least 70 KWH.
The bill's payed

And aren't you special Chillycat, bragging about how big a consumer you are. Awesome.
sure heating may not save a whole lot but cooling will. depends were u live.
