Nest Thermostat E w/ WiFi Remote App Control Expired

It does that, but it does a bit more. I have mine to set up with schedules for my activity, and I set it up to detect my location on my phone periodically and adjust my thermostat as needed. I can use it with my Google Home as well, which I'll admit is more novelty than anything.

For example, I go in to work at 7 and typically come home for lunch around 11 or 12. It detects I'm not home and goes to Eco mode and lays off the heating/cooling until around 11 when I generally come home for lunch. Then it kicks in and heats/cools. Or if I'm just not home all day, it doesn't run much but literally when I pull in to my driveway, I hear the AC start. It's neat! The numbers don't lie. I pay a good chunk less each month and I am very happy.

If you are already manually operating your HVAC system as little as possible (in a thrifty manner) a learning thermostat or similar will not net you very much in savings on your heating/cooling bill.

It really only helps people that leave their HVAC system running extended periods, even when unnecessary. With a learning thermostat they wouldn't feel a difference in comfort, but their monthly bill would be significantly less.

I just bought the e for my upstairs from the target madness happening last night and installed it a few hours ago. Before the e I had 2 3rd generations downstairs which I bought 2 weeks after release. There is barely any difference in functionality and I actually like the design of the e better. However a huge caveat of the e is that it has a much less ports. The e only comes with a R,G,C,W,Y,OH wire ports. The 3rd gen, on the other hand, allows for a heat pump, humidifier hookup, etc. You should probably check the wiring compatibility on Nest to make sure it works with your system (I attached a link below)

https://nest.com/widget/compatibi...mode=guide

In that link you will take off your old thermostat cover and enter in your wires. It will then recommend whichever one is compatible. In my case both are as my home was constructed 6 years ago. One big thing to note during installation is this: The Nest E does not have a Rh or Rc port like my old thermostat did. I was confused since I entered in Rh when I was doing my check and it said the Nest E is compatible. The Rh/Rc (if connected by a jumper wire), remove the jumper wire and simply connect it the master wire to R. In other words on the Nest E your Rh wire will go into R. On the 3rd Gen there is a specific port labeled Rh. This was something that tripped me up. Your system will work fine and it shouldn't affect anything.


Now onto why they even created this thing. Well...Nest was getting many complaints about the older gens with a LCD screen consuming too much power in the background restarting the furnace and tripping the breaker. Note this ONLY HAPPENS IN A FEW VERY OLD SYSTEMS (think 20-30 years old). The old nest would powerhog current from the furnace causing the control wire power (your C wire) to fluctuate. Nest eventually decided to create the E as it consumes much less power in its operation due to the display it uses. So in reality this thermostat is ideal for homes that don't have a reliable C wire or if their system is old and prone to issues. I would say a good rule of thumb is if your old thermostat is battery powered check and make sure there is a c wire. If there is you are safer buying the e as the electrician probably knew the c wire wasn't able to support the thermostat which is why they added a battery supplement. For hard wired thermostats any version should be fine. Just focus on that C wire. The nest has a battery built in as well to help maintain a steady stream of current. For me none of these issues were present as my furnace was made within the last 15 years and I have a good C wire. All in all the reason I bought the e was price, a new design on the market, and a ridiculous sale going on.
