Google Nest Learning Thermostat (4th gen) + Nest Temperature Sensor (2nd gen) - Silver

Love the look of this thermostat. It was easy to install but I also had a google nest before this one. The thermostat has all the functions you need and pairing it with your phone helps you track not only the temp in your home, but also how your furnace is functioning.

I had purchased a previous version of the Nest Thermostat (3rd Gen) and had issues with it holding a charge and connecting with Wi-Fi. So I returned the older model and splurged for the latest version in the Gold finish. OMG! I am still blown away at how amazing it looks. The mirror finish is stunning and its very easy to read when the dial turns on. Installation was actually easier than the 3rd Generation model (which was pretty easy) and set up was done in about 10 minutes. It connected to my Wi-Fi immediately and did a quick software update. The remote temperature sensor was added in less than 5 minutes. I travel a LOT for work and having total control of the HVAC system through the Google Home app is easy and I can see both the t-stat and the sensor in the bedroom. You may think that I have been bribed or compensated by Google, but you would be wrong. I simply want everyone to know that this is a very high quality product that looks amazing and WORKS.

Had to replace my Nest Thermostat 3rd gen with this Google Nest Learning Thermostat 4th gen. My cat loved to jump up on wall to knock the 3rd gen off wall so he could play cat hockey with it. This activity finally killed the 3rd gen. The installation was so easy and fast after I removed the 3rd gen. Very nice thermostat.

When one of our 3rd Gen Nest Thermostats stopped working, I decided to replace it with a 4th Generation Nest unit. Oddly, the mounting hardware for the 4th Generation is completely different from the 3rd Generation, which is annoying. The wiring backplate is incompatible, as the 4th Generation has a different electrical connector to the thermostat. One nice thing about the new backplate is that there is a light built into the bubble level which signals voltage on the Rh or Rc wires from the HVAC unit, implying you won't need a dedicated C wire for power. Unfortunately, this is many times not the case for the 4th Generation, lit bubble level or not. When I properly mounted and connected the 4th Generation thermostat, the setup app on my phone reported that there was "no power" on the R wire, even though the bubble level was lit, and I could measure the voltage on a multimeter. There was no way to get around the error message in the app. A call to Google support was completely useless. The support person clearly didn't know why the setup app falsely reported "no power", or whether or not the 4th Generation thermostat required higher voltage on the R wires than the 3rd Generation thermostat for operation without a C wire. An internet search revealed numerous people posting on Reddit and other web sites of the same issue I was having. How could Google support not be aware of this? Depending on your view, the difference between the R wire voltage requirements for the 4th Generation from the 3rd Generation thermostats is either an undocumented design change, or a design flaw. Personally, I consider it a significant design flaw, especially that it is not documented in the setup instructions, and there is no warning of this anywhere in Google's documentation. After spending about two hours removing the 3rd Generation mount, installing the 4th Generation mount, waiting for the callback from Google, and figuring out the root cause myself, I unmounted the 4th Generation Nest, packaged it back up, and returned it. I ordered a new 3rd Generation Nest from Amazon, and it works flawlessly with the HVAC unit. One attraction of the 4th Generation Nest is that the "maintenance band", the temperature variance range at which the AC compressor cycles on and off, is manually programmable, while on the 3rd Generation Nest it is not. There have been complaints that the 3rd Generation Nest's maintenance band is only two degrees F wide, which in some climates and homes cycles the compressor too often, and is blamed for excess wear and premature failure on the compressor. (AC units and heat pumps both use compressors.) So if you have a C wire in your compressor-based system, I recommend trying to use a 4th Generation Nest. Another trick which works with both generations is to use a remote sensor in a different part of the room or another room where the ambient temperature doesn't vary as quickly, to reduce compressor cycling. I use this trick for our 3rd Generation Units, and it also works for 4th Generation thermostats. Note that using a remote sensor this way may require some experimentation to get the desired result, while the feature to manually adjust the maintenance band makes it quicker and simpler. I really like the Google Nest thermostats when they're working the way they're supposed to, but the lack of backward functional capability from the 3rd Generation model to 4th Generation model is inexcusable, since there's no warning about it. And Google support is ineffective in helping less technical buyers. The least Google could do is document the issue properly on their web site.

Amazing device for saving energy and comfort. It was easy to install and looks great in my living room!

I upgraded from the Nest Learning Thermostat 3rd Generation so I've had some experience with these thermostats. It does look more modern, upgraded and slimmer so this was an added because I was actually remodeling my home. My only gripe that knocked it from a 5 star to 4 star was because they removed the thermostat's functionality from the Nest app and now you can only use Apple Home after you install it in the Google Home App. You can control it with Alexa and Google Home devices but I never like the Google Home App so for me its a recommend still because it is a great product that helps you monitor your AC usage, control while away and it provides monthly reports to show you how to efficiently use your AC system

Yikes what a neat device! It does learn from your daily movements to adjust either heating or cooling regime when you leave the house. It compensates for outside temps and figures out the time required to meet your set temps when you return to the home. There are many settings for fan timings ( to circulate stall air). To use the devices many features one should use the Google home app which requires WiFi. Should this be a ‘no -no’ it can be easily programmed directed by using the thermostat. Our one negative comment is the price. A Generation 3 unit costs less but lacks conservation features of this unit. Time will tell if the units features will save us energy costs. Google emphasized it will save.

The Next Gen 4 Thermostat is a fantastic addition to my smart home setup! It’s incredibly easy to install and use, with a sleek design that looks great on the wall. The intuitive controls and app connectivity make adjusting the temperature effortless, even when I’m away from home. The energy-saving features have already made a noticeable difference on my energy bills. I also love the detailed reports and insights on energy usage. Highly recommend this for anyone looking to upgrade their home’s climate control system!

Don’t buy if you live in the UK they work, only designed for the USA market. My installer said they don’t work in the UK
