Again, sounds like unfamiliarity with the options. Ther was a brochure that came with the product that explains how it learns. It really isn’t that hard, people.
78 sounds like a good temp to me, we usually set the AC to 82-83 for us, but when guests are there I have seen them go as low as 64!
And I can’t stand the Honeywell! I have no idea what all those icons mean. I think the user interface is awful. I would take the simple display of the Nest any day. Just turn the dial! Push the face and see more options. No wifi or app nvolved.
All of my extended family that has installed the Nest has said it made a dramatic improvement in energy efficiency and lowered power bills and we are all in FL. We all sleep at 68! 
Huh? on icons for Honeywell. Mine has up/down triangles , word and numbers. Temp for heat and cool (with triangles), time, temp, options with words all on the screen at the same time. Old school to some but easy to make changes. Nothing like the obscure !@#$%^& symbols used by Windows 10 that make me feel language is a lost art.
Nest updated their app last night. Not sure what it included, but since they also have new features with their camera (you can set it to recognize certain faces) it might have been for that component.
Funny- last night I was in our guest room and it felt warm, so I turned down the a/c on my phone. But i didn’t feel the a/c come on and I wondered if this was what one of the posters here was talking about. But then I looked up… the vent was closed! The a/c was on and as soon as I opened the vent, voila. Nice and cool. Operator error!
Some of these thermostats have a feature called “geofencing” that can tell when you’re returning to a few mile of your home and begin getting the temp to where you like it. I personally have a Lennox thermostat that I control from my phone and love being able to kick the heat on from under my blanket when I get cold!
My biggest problem is H turning up the temp for the A/C when I’m gone- there will never be an app to control that! I find myself checking upon entering and hitting the schedule space to go back to 78 from 79. My upper limits of tolerance now that I’ve adapted to warmer temps.
Do you have the app on your phone too, @wis75? You can just turn it down before you get home. Will he hear it and mess with it? Thermostat war!
I don’t think @wis75 has a Nest.
We don’t have a Nest either. I think it’s a matter of personal choice.
So @wis75 has the Honeywell? Not familiar with its features so don’t know options, other than negotiating with her DH and also running ceiling fans, if he wont turn down the temp.
I just hit the run schedule space on the Honeywell touch screen. We haven’t bothered with the Wifi settings as we are retired and home a lot or have irregular in/out times. No thermostat can “learn” our habits as we don’t have any.
On the Honeywell, there is an exclamation point - what is that? And if you just touch the screen in a random spot it puts it on Hold and then where do you tap to get rid of that? What is the house icon? It is possible we are talking about different models. Our 2400 sq ft house came with an inexplicable 6 heat zones and currently has 4 different models of thermostats. It’s a nightmare to keep track of how to program them. They can’t all be Nests because of difficulty getting the extra 24V wire to them.
Not entirely true.

That works great for folks who always carry their phones on them. What if you have more than one phone per person and don’t always carry both? What about folks who have a phone that is locked by thier IT for download of apps?
This is going back and forth.
Clearly…the Nest thermostat is NOT for everyone. Neither is the Honeywell…or any other thermostat for that matter.
If you like the Nest and all of its features, fine…get a Nest
If not…stick with what you have…or whatever.
@thumper1 - that was a legitimate question in my post. Assuming Nest tracks phone movement… how does Nest recognize the phone being left at home versus person taking a nap?
If the primary phone is at home, it will respond to that. Then again, if there is no movement in the house, it may go to eco. Not sure what happens with operator error 
Thanks jym. So no distinction between those two situations. Does it use the GPS-like locating in its tracking function? Lets say you are on the bus and coming home… Will it turn the heat on automatically when you are within X miles from home?
@BunsenBurner - look upthread. The way to manage the multiple phones issue is that one person’s phone (mine, in our case) is the primary, and DH’s is added as a “family member”. He can control the thermostats from anywhere just as I can. The difference is that the thermostats know to pay attention first to where my phone is, and then where his is. I assume if it knows one is home, even if its not the primary, it will assume someone is home. This is why I took the app off my ipad. So I didn’t give it mixed messages.
