Gorgeous display but I miss the Nest App
Beautiful new Nest thermostat. Replaced an older model so that I could get “Matter” functionality (and have the option to control in Apple Home). That part works great.It was easy to swap the old unit out too. Was worried it would also delete or disassociate all my various room sensors, as I rely on those, but that wasn’t the case. Those are all tied to my Google Home account directly, and linked right back up.Wish I could take off half a star because the old Nest app will no longer work with this… Google Home is fine and I’m pretty sure I’ve figured out how to do everything that I used to with the old Nest app, but for anyone who has difficulty with “change”, or who has a bunch of Nest cameras that you also manage with that app, be warned. You will have to switch to the Google Home app to operate this new thermostat, at least initially, before porting it over to Apple Home (if that’s your bag). Even then, full functionality and control will only live within Google Home.

A Game-Changer for Home Comfort and Energy Savings
I recently upgraded to the Google Nest Learning Thermostat (4th Gen, 2024) with the Nest Temperature Sensor, and I am absolutely thrilled with the results. This smart thermostat has exceeded my expectations in both performance and convenience.Design & AestheticsThe Polished Gold finish adds a touch of elegance to my home decor. It’s sleek, modern, and looks great on the wall. The display is bright and easy to read, even from across the room, and it has a nice, minimalistic design that fits seamlessly into any space.Functionality & PerformanceThis thermostat is incredibly intuitive and learns your preferences over time. It automatically adjusts the temperature based on your habits, which means it keeps the house comfortable while saving energy. The Adaptive Eco mode is fantastic for reducing energy consumption when you’re away or asleep, and the integration with the Nest Temperature Sensor allows for more precise temperature control in different rooms.Smart Features & IntegrationThe Nest Thermostat works beautifully with both Alexa and the Google Home app, making it super easy to control with voice commands or via your phone. I can adjust the temperature remotely, monitor energy usage, and set schedules—all from my smartphone. The setup process was quick and easy, and the app interface is user-friendly.Energy EfficiencyOne of the standout features is the energy-saving capabilities. After using it for just a few weeks, I noticed a decrease in my utility bill, thanks to its energy-efficient settings and ability to optimize temperature settings based on my lifestyle.Final ThoughtsIf you’re looking for a smart thermostat that combines style, convenience, and energy savings, the Google Nest Learning Thermostat (4th Gen) is the perfect choice. It not only looks great but also works seamlessly with your home’s smart system to create a more comfortable and energy-efficient living environment. Highly recommend!

It just works and easily.
I had a boiler and AC on separate units, old wiring, no c-wire, this magic thermostat allowed me to combine them! It works, it just works, it is quality make, good design, and honestly the easiest to use in the industry. Sure it probably has hidden spy features but what doesn’t.

May not work in HVAC systems without a C wire, when the 3rd Gen Nest Thermostat will
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.

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!

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!
