Re: CT30 and 3M50 Remote Thermostats.

I read these statements here all the time but never get the details as to how much money a "bunch of energy" represents.

I'm waiting for my first bill, but what I can tell you is that, by using the away/remote-on features while we were out shopping, my furnace runtime this past weekend was half of what it has been during the week.

Again, I need more time to correctly analyze this (a heating bill, for starters), but so far, so good.

Oh - the other Big Deal that I forgot to mention; the Nest also has a humidistat integrated in it, so I can wire the whole-home humidifier to its control. That's a Big Deal because the way it's wired right now (from the previous owner who installed the furnace), the humidifier is only on when the furnace is running, and there's no way to run it along with the fan when heat isn't being called for. That means that the house humidity is lower than I would like at about 32-35%. I'd prefer 40-45%. My sinuses suck and are very sensitive to humidity levels. I have the requisite relay and transformer to correctly wire the humidifier - that's a project for the next available weekend ... Also going to run a Common wire to the Nest while I'm at it (the t-stat wiring now dates back to the '60s and has been spliced more times than Evel Knievel.

Can you translate those pictures? Those bars mean nothing without total furnace times and outside temperatures.
I am not saying that turning down the thermostat doesn't save energy (it does), but for at least an average insulation the savings with short duration setbacks are minuscule. The savings come when the house manages to cool down significantly for extended periods of time.
Again slightly O/T, but any half-decent humidistat can activate the blower when there is a call for humidification.

What application are you using to generate that data?

Correct on all counts. I do travel quite a bit for work, so if I can setback from 7:30-5 (while my wife isn't home), that's significant.

Even moreso, if I'm traveling (as I am this week), I can set the house to a low temp and turn it up when I land so it's warm when I get home.

For a house where we used to keep the thermostat at 68 all year, this is a game changer.

And you're right about a decent humidistat; unfortunately the previous owner of my house (I moved in a year ago) went cheap and put an in-duct manual humidistat that's essentially an on/off switch. I want more intelligence!

As for the app generating the report, that's just the Nest's web interface. I'm contemplating setting up MRTG or somesuch and connecting to the Nest API for some light reporting & analytics.
