Nest Level: Unlocked
I’ve owned every Nest thermostat since the first generation, and this is by far the biggest improvement yet. The bright display is highly customizable and keeps all the familiar Nest features, but in a sleeker, more modern design. Setup and control now run through the Google Home app rather than the legacy Nest app, so that is important to know before you upgrade. Google is phasing out older Nest models, and this unit is an excellent replacement if you are still using one of those. The included remote sensor is especially helpful in multi-level homes, allowing the system to detect cooler areas, such as a basement, and adjust heating to keep the whole house more comfortable.

A true Smart Thermostat
This is an easy to install and easy to use thermostat. It is actually smart and adjusts to your needs. While you need Google Home to set it up and dive deep into some features it also works with Apple Home. You can have Siri adjust the temperature just by asking. Also the look is amazing

Wish I'd bought these sooner
Being a non-handy new home-owner I had it in my head that replacing my legacy smart thermostats - which I could never get to work properly - would require the help of a professional so I just kept putting it off and suffering the cost and comfort consequences. Finally, seeing the headlines about the 4th gen Nest got me to do a quick google and sure enough it seemed my wiring would be compatible AND that I could even do it myself. So I bought one Nest, followed the instructions and within maybe 35 minutes had it up and running. It was so easy to install, and also to program! The very next day I bought my second one (which I was able to install in at most 15 minutes). Plus two sensors. Two weeks in, everything is working exactly as it should. And they look beautiful and the weather forecast display is genuinely useful. Tremendous!
