The Nest E is a great smart thermostat that’s comfortably among the most stylish and easy to use on the market, but as it stands in the UK, there’s not much reason to opt for the E over the existing 3rd gen Nest, which has some extra functionality for a similar price - excluding the potential cost...

Very easy to install. Had a bit of trouble with the upstairs thermostat, as it was wired different than the downstairs. But it seems to work well after third attempt.

I bought two of these a few weeks back and replaced the old digital thermostats in my house. This is a really well-designed product and installation was obviously at the forefront of their design objectives. It was much easier to install than I feared it would be great.

I use it in my private residence and it is really great, offering so many heating and cooling options. It was easy to install and connected right away to my internet. At this time there is nothing I don't like about it.

The Nest was easy to connect and program. I don't need to be giving Google more info about my family, so I've turned off the learning algorithms and have it set just to programmed cycles and manual controls.

I was able to install the Nest very quickly, using the provided cover plate as well because I was replacing a rectangular programmable thermostat. It connected easily to my Alexa system and Ive been able to control it by voice or through my phone.

- Save yourself the frustration and money, just get a simple wireless thermostat for much cheaper or the Ecobee ones that come with multiple remote sensors, which is seems to be more useful than this at a similar price

    - Looks nice

    - The "smart" or "learning" feature is bogus. Perhaps it works for people who live alone and have a very rigid schedule, but it didn't work for me and my roommate. Started setting the temp higher to our discomfort because I guess we set it higher when it was really cold outside one day, (which makes...

We have a vacation home. When the temperature is above freezing and we are away I turn the heater off from my mobile device. When the temperature drops I turn it on. When we are coming I turn on/up the heat,or in summer the air-conditioning

    Confusing Controls

10 July 2018

Grabbed this in the copper and so glad I did! I think the hardest thing was shutting down the power to my house. Yes, in other words, it's that simple to install. Full disclosure, my house is newly built but I believe Nest worked it out so no matter the house's age, you'll be able to use this...

Easy set up. Very impressed at the engineering and thought behind making sure the average homeowner could easily install the unit straight out of the box.

    App control from the smartphone, easy install, easy to track energy use. Pays for itself.
