I was actually coming here to bump this old thread to ask everyone what their preference was on this. My Nest v2 will be here tomorrow and I was just pondering whether or not I'd program it myself or let auto program do it's thing. My schedule is pretty set, except for my weekends, so I thought programming it myself may be the best bet.
I was also going to ask what the consensus was on using manual away. How long does one need to be "away" before it's worthwhile? Should I go "away" just to go do my grocery shopping, go out to dinner, etc or use it only if I'm going to be gone for longer periods?
Well, I can tell you that auto-away kicks in about an hour after you leave the house.
For me, using the away feature (either manual or auto) makes a big difference on consumption.
