Thermostats are a huge pain in the ass. We had a Honeywell programmable doohickey, and it was terrible.
It was reasonable for what it did - it's not like it would refuse to heat/cool the house to a temperature that it was programmed to.
That part was fine.
The problem was programming the thing was like trying to make love to a goat; you just wrestle around with the thing for a while and finally give up and yell "I'm finished!"
I don't know HOW I managed to do it, but at one point this winter, Sunday nights around 10 PM the temperature would plummet to 65 degrees downstairs, which led to a temperature of around 63 degrees in the front bedroom where our child was cosleeping with Mommy.
I'll admit, that's user error.
The thing's hard to program.
Enter the Nest.
Here it is both asleep (from a distance) and awake.
It's unobtrusive and works just like an old fashioned thermostat: twist it in a direction to turn the temp up or down.
But the info it displays is pretty cool - once it figures it out (it
took around 2 weeks for ours I think) it'll tell you how long it will
take for the temperature to go up.
It's color coded as well; red/orange for heating, blue for cooling.
The best part is the thing's connected to your wireless router, so your phone is capable of controlling the thermostat.
I can control the temperature when I'm laying in bed. Living the dream!
We've had it for a month now, and so far I like it a lot. The temperature seems more accurate than the Honeywell was. This isn't a very interesting month for it in terms of "is it saving me money?"since the temperature has been swingy and we've been heating but rarely needing it over the course of the night.
I love the web interface, and the analytics seem like they are going to be very interesting as time goes on. I'm interested in comparing the time ac/furnace runs and billing.
Also, it is really cool how it wakes up as you approach it. Feels high tech.
