I mostly agree with you. I'd be happy to keep the temp around 62 deg F all the time. That's the coldest I can stand for long periods with just a sweater, wool socks and a blanket to cover my lap. Any colder and my face / hands freeze. I can't ware gloves while using my PC and have no desire to spend 8 months of the year wearing a face mask/scarf.

The compromise I made with the wife is having the heat on in the evening, when we're pretty much home for the night, and Saturday and Sunday. The programmables are just to make sure that she's not leaving the temperature up after we go to bed. I actually like being snuggled up in a warm bed and have the room colder, I sleep like a rock in the winter, but then when summer rolls around and we have those two or three weeks of 80+ deg F heat I can't sleep at all. We don't have an AC, it's only a few weeks out of the year it's ever that hot here. We're currently in the middle of the yearly heat wave here, it was 78 deg F last night when we went to bed. I use to live in North Carolina when I was a kid where it was way worse. It was almost the opposite, in the summer you kept the AC on and never left your house because it was over 100 deg F and you'd get heat stroke, in the winter you spent most of your time outside because the coldest it normally was for a few weeks out of the year was 40-50 degs F, nothing a decent jacket and long johns can't handle.

Story In Coming:

I remember one, shortly after we moved to NC from Canada, I got up late and had breakfast then went out to wait for the Bus. When the bus didn't come I walked to school thinking I'd missed it. The school was all locked up and I eventually went home. Turns out school had been canceled because of ice on the roads. All I saw was a few puddles, but no actual ice. I still get a chuckle thinking about it. Coming from Canada, it felt like school wasn't canceled here until you were up to your shoulders in snow.

My preference is only to keep a house as minimally warm/cool as mechanical concerns allow... i.e. Heating is always set at 50F (10C) so that pipes don't freeze, and cooling is always set at 85F (30C) so that electronic equipment doesn't overheat (goes for pets, too). With that methodology, there's no benefit to even basic programmable thermostats.

I don't see the benefit in maintaining a temperature closer to 70F (21C) for human comfort, as it's necessary to dress appropriately for outside temperatures, anyhow. Going inside/outside repeatedly, with a huge temperature differential, is very uncomfortable. Instead such a "comfortable temperature" tends to just cause headaches, hot flashes, etc., and causes a more time-consuming burden of dressing/undressing when entering/exiting.

Now, if I had the opportunity to design my own home, I'd spec it with insulated pipes (among many other things) so that they wouldn't freeze even in very low interior temperatures. Then maybe I'd have incentives and a practical case study to find the lower limits of human comfort and this concept. But until that time, those high/low temperatures are the limits whether the building is occupied or not, eliminating the need for any changes throughout the day (or week).

I am sympathetic to the wife/girlfriend factor, as well as the need to manage humidity (condensation, mildew and mold) in some areas, and with some (usually, poorly-insulated) homes, but I can still usually make this concept work well-enough.

The one place a connected thermostat comes in handy is with vacation or rental property. I have a place in Florida and believe me, you want that place cooled down when you arrive. But you also don't want to run the A/C for 20 days when it is unoccupied. A connected thermostat is perfect for this. Also the system can monitor the temperature and send notifications if the current temperature goes outside of set boundaries (handy for avoiding frozen pipes or other extreme temperature disasters). As for securing it against outside unwanted control, so far sticking the entire system behind a VPN has worked good. So the thermostat (which has pretty lousy security) is not exposed directly to the internet; it sits behind a firewall and can only be accessed via VPN.

I'm partly with you. I live in Canada and I have programmable thermostats. In the winter there's no reason to have the house at a human comfortable temperature all the time. The thermostats are set to 62 deg in the winter. We suffer the cold in the morning because we're only in the house long enough to have breakfast then we're out the door for the day, but the thermostats all kick in about 30 minutes before we get home to heat the house to 70 deg. Then they shut off about an hour before bed.

The reason this works well for us is because my wife loves to crank the heat to 75 degs, then never remembers to turn it off, which has costs us a fortune in the past. With the programmables she can still occasionally crank the heat, but the thermostat always readjusts automatically when the next trigger time kicks in. They're also easy enough to set to a constant temperature if we're going on vacation and then we can just hit the "run" button to put them back on their regular schedule when we get back.

Where I agree with you is, it's just a convenience. We could survive perfectly fine with the analog mercury thermostat. These are just easier so we don't always have to remember if they're on or off and the house is warm when we get home in the winter. In the summer I just flip the switches and turn them off altogether.

As for thermostat settings, I prefer the simplest option: a single fixed temperature that the system maintains +/- a degree or two.

The house itself should be efficient and have enough thermal mass to prevent large temperature fluctuations throughout the day anyway. If you feel the need to "adjust" the heat/cooling at different times of the day, perhaps you should invest in more insulation or higher efficiency windows instead of a fancy internet connected thermostat.

We just finished a replacement of a 40 year old gas furnace for our basement and first floor. Our second floor has separate heating and cooling, only about 10 years old. My wife and I remodelled the 120 year old "worker's cottage" ( http://moss-design.com/worker-cottage/ ) style home in the mid 1990's. We kept our original furnace at the time. in 2001 we hired a crew to dormer the roof and finish the second floor (we had more money at this time and didn't have to do the work ourselves). At that time we installed separate heating and cooling in the second floor. We used a programmable, but non-connected thermostat.

Just this summer we replaced the old furnace for the first floor and basement. The furnace dated from the late 1970's and was not too efficient. We had central air added as well, along with some duct work changes.

I worked with the HVAC contractor to choose the best thermostat. We looked at all the options and the clear choice was a standard programmable thermostat. The benefits of a smart, connected thermostat were negligible. Once programmed, the standard thermostat adjusts and maintains the temperature perfectly on your schedule. It works well, costs less and is not vulnerable to cyber-attacks.

The benefits of a connected thermostat are few compared to a programmable, but the cost is much greater. Not really worth it.

It wasn't easy to squeeze so much info down into a short summary, without either making it overly technical and incomprehensible to a general audience, or losing so much that the significance isn't obvious. So quite a bit was glossed over or only hinted at.

It should be said that the WebM project also had several large supporters, yet VP8/VP9 decoding only made it into a tiny amount of hardware, products and services. Google was also slow about making YouTube videos available as VP8/VP9. But they did make progressively more headway in software and standards, so it's a hopeful sign that so even more major organizations are interested this time around. Perhaps this dual standardization process, making it no longer just a Google's own codec, will lead to the wide adoption the WebM project was working and hoping for.
