You can tell a stupid amount of personal habits from their data. You can tell precisily when i go to sleep, when i wake up, when i take a shower, when i power up my servers (if i ever power them off), when i use the stove to cook dinner, etc
You cant tell if im in or out of the house though, as i hardly ever use lights, and if i do theyre cfls that dont consume enough energy to cause spikes.
if you're home, you can push the damn thermostat buttons by hand.
Yeah, but what about when I go out for a play date and don't know when I'll be home again?
you leave your heat on. It probably costs more to heat it back up if you let it get cold anyway.
By that logic there's no reason to use a programmable thermostat at all.
My only problem with it all is that since I'm home all day most days I need to be flexible. I only really want to reduce or increase the temp (depending on season) when there's nobody here which isn't very often. I can't just program for different times of day or anything. So being able to text my thermostat and say "please make my house comfy, I'm on my way home" might be useful.

Wrong. That ends up costing more. Not much more, but more.
that all depends how cold you let it get, theres a ridiculous amount of variables.
Thermodynamics spankage in 3, 2, 1...
too many variables for proper spankage.
Although it is rather strange that i have to correct people on thermo stuff like 3 times a week..... how does that keep coming up so often.

You can hide behind it all you want, but the costliest comparison of reducing "on" times is that its a huge energy spike in starting the HVAC system. Less starting = less energy. And at least here in Florida, as the house gets warmer during the summer, the heat transfer slows as it nears the external temperature reducing costs further.
You didnt post anything. Or if you did, i missed it.
Im not wrong. Fridges cool from the freezer, which is then piped out to the fridge as needed.
There may be evaporative coils physically behind the fridge, but the cool goes into the freezer.
I posted a ton. Links, discussion, graphics. WAW even reposted one of the links. On my fridge, the cool doesn't just go into the freezer and a lot of other fridges don't work on that principle either.
