After buying the Nest E we installed it (which took us only 20 mins or less). We immediately noticed a few things. We previously had to always keep the heat at 72 degrees with Nest 70 degrees felt the same. We loved the eco option, the ability to control the heat/ac from almost anywhere and not having to get up to change the temperature. We love it and if you are researching... JUST BUY IT!
I’ve been using Nest Thermostat 2 nd and 3rd generation for a few years now and was very satisfied with the product but decided to switch to Nest Thermostat E and so far it is performing very well and beyond the expectations. I recommend this product very strongly.
It can be so much better if on device can do it all. Thermostat, smoke alarm, intercome, security camera, motion detector. Also the battery can be more common, like AA or 18650. It could be even much better to have MY smart home server with cloud backup. Today, Smart Home is not so smart. Turning lights on and off is not smart. The technology is here long time ago. As a thermostat, it's good.
I DON'T HAVE THE SYSTEM RUNNING ALL THE TIME SINCE IT'S ONLY USED AS A WORKSHOP, BUT IT'S SO NICE IF I FORGET TO TURN IT OFF OR TO ECO, I CAN DO IT FROM ANYWHERE ON MY PHONE. VERY WELL BUILT, LOOKS GREAT AND WORKS AWESOME. LOTS OF FEATURES I THOUGHT WOULD ONLY BE FOUND ON THE REGULAR NEST. YOU CAN READ IT FROM ACROSS THE ROOM. WE NOW HAVE THREE OF THEM...SHOP, HOME AND BONUS ROOM.
I have only had it running for two days, but I am loving how it performs up to this point. It was easy to install the thermostat on the wall, comes with its own leveler. It was not hard to connect to the phone ap.
