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

I was trying to determine if I was having an issue with my thermostat, my furnace.. or both (yikes). I had an Ecobee, which had been installed for roughly 10 years. Worked great, then I started having issues with getting heat to turn on in my house as it should. Process of elimination, I opted to try Google Nest. I LOVE this. Massive upgrade to what I had, easy to install, and the issue I was having became clear to be the thermostat and not my furnace. In fairness, it likely just needed to be upgraded, but I have other Google Home items and have heard good things about Nest. I have been very happy with it already. And unlike the Ecobee where I need to set schedules for 'home' vs 'away', etc.. this is a learning thermostat, so it naturally learns when you aren't home and just turns the heat off (within reason - I haven't woken up to my house being below 50 degrees or anything). If I am gone all day, the moment I walk in the door and the Nest "sees" me.. it kicks on to heat. It's also very sleek looking, but super easy to use so it doesn't come off super techy or anything. Highly recommend!

This thermostat has been a fantastic upgrade for my home. Installation was straightforward, the display looks great, and the included temperature sensor helps keep the rooms I use most comfortable. The smart features are easy to use and have made managing my home's temperature much more convenient. Highly recommended!

The Google Nest has been a great thermostat for me. It replaced a wall unit in a house I purchased that was very old but still functional. Setup was relatively easy, as well as getting the wires into the thermostat itself! The ability to control your homes temperature from your phone, as well as schedule home temperatures for sleep, daytime etc is a game changer. You can also customize eco mode for when you’re away. Over time, the cost savings per month will pay for itself in a few years compared to a cheaper thermostat. I highly recommend!

Three reasons I like this product: 1) C-Wire: I don't have a c-wire available. There are VERY few modern smart thermostats that claim to work without one. I first tried one of the others, the Sensi. It did not have any apparent easy way to determine in advance if it would work without a c-wire. It didn't work for me. The lack of an easy advance tool cost both of us time and money; a lose/lose. A wrote a well-deserved 1 star review of that product. This product does have a very easy tool to determine in advance if it will work without a c-wire. It took me literally 10 seconds to use that tool & be confident this would work. And, it does, in fact, work great without a c-wire. 2) Functionality: It comes with a remote temp sensor which is a new thing for me and a great idea. I put mine in the bedroom. It was crazy-easy to set up and I really like the simple interface letting you choose when & how you want the thermostat to use it. It says you can add more of these if you want. Programming a daily schedule is incredibly easy as is making quick adjustments to that schedule. It has all sorts of other features such as auto-adjusting based on who is home, learning your patterns & making further auto adjustments, accepting voice commands, and so on. I do not want to use any of those things. They made it very easy for me to just say "no thanks" to all of those things and still have a nice seamless experience. 3) Appearance: I hesitated to buy this product because it is round while my previous thermostat was rectangular and the wall is messed up everywhere behind the area of the old thermostat. Yes, I can patch a wall and paint it - but, no, I don't really want to if I can avoid it. It was a pleasant surprise to me that this thermostat came with an optional large faceplate that is made to cover up the bad wall in exactly my situation. I used it and it is great. Privacy is a concern but that seems to come with just about everything these days so - I don't know - just get over it? I recommend this.

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.

Better than that old T we got with the house. Super easy to use and the multiple sensor function is great feature. Has helped with efficiency in the house. Wifi feature works great. Display is super easy to use and you can use your phone. Noise level is none.

Only reason I had to buy a new one is cause Google was shameful and discontinued support and Alexa functions on the previous version. I do like the look of this one though it does give many options for the screen, which is pretty cool. There’s a lot of information you can choose to have a display.

It was time to upgrade my 20 year old Honeywell thermostat and decided to choose this Google Nest because it looked like the most smartest and modern smart thermostat on the market. I went with Obsidian Black because to me it’s the best color trim. I like everything about it and I can control the temp with my phone no matter where I am. Setup was a little difficult because even though my C wire was there, it wasn’t connected to the furnace in the attic. Took a good extra 20 minutes just for that part. Just make sure you have the C wire ready on standby for perfect results.

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

I bought a Google Nest Thermostat from Amazon, and initially, I wasn’t sure how to install it. I contacted the supplier, Mr. Mumtaz, who was incredibly helpful. He came over and installed it for me and did such a great job that I ended up getting one more thermostat, which he also installed. The devices are now working perfectly, and I’m very satisfied with the performance. Highly recommend both the product and the excellent service!

I recently upgraded to the Google Nest Learning Thermostat (4th Gen) with the Nest Temperature Sensor (2nd Gen), and I couldn’t be happier with the purchase. This device not only modernized my home but also noticeably reduced my energy consumption. What I Loved: Adaptive Learning – The thermostat quickly learned my schedule and started adjusting the temperature automatically to fit my lifestyle. I barely have to touch it now! Sleek Design – The circular display looks clean and futuristic. It fits perfectly with my home décor. Remote Sensors – The Nest Temperature Sensor is a game-changer. I placed it in my child’s room, and the thermostat now prioritizes that area, ensuring a comfortable temperature where it matters most. Energy Savings – Within the first month, I noticed a drop in my energy bill. The Eco Mode kicks in when we’re away, and it does a great job of managing heating/cooling efficiently. App Control – Adjusting the temperature from my phone (or even voice control with Google Assistant) is incredibly convenient. I can tweak settings from anywhere, which is especially handy when traveling. Room for Improvement: Price – It's on the higher end, but considering the energy savings and convenience, I see it as an investment that pays for itself. Installation – While not overly complex, some people might prefer professional installation if they aren't familiar with HVAC systems. Final Thoughts: If you're looking to upgrade to a smart thermostat that blends tech, energy efficiency, and comfort, this is it. The combination of learning technology and temperature sensors ensures your home stays cozy in the right places at the right times. Highly recommended!
