Nest Learning Thermostat (4th Gen).
Google's flagship Nest with Soli radar proximity display, Matter support, and the most refined adaptive learning algorithm on the market.
The Verdict.
Gavler Meta-Score
“The right pick if you live in Google Home, value design, or want the easiest install in a no-C-wire home. The Soli radar display is genuinely best-in-class. The reason to buy the Ecobee Premium instead is broader ecosystem support and SmartSensor's slight edge in multi-room control.”
The Gavler Verdict
Precision Engineering
Soli Radar Proximity Display
Built-in radar sensor changes the display from glanceable to interactive based on how close you are.
No C-Wire Required (Most Homes)
4th-gen redesign eliminates the C-wire requirement in most US homes — the easiest smart-thermostat install in the market.
Matter + Google Home Native
First-class Google Home integration plus Matter support for Alexa, Apple Home, and SmartThings.
Technical Specifications
The Scoreboard
Top of every Google-Home-centric roundup; second pick on most multi-ecosystem roundups behind the Ecobee Premium. Community ratings reflect strong Google-Home loyalty offset by Apple-first households downgrading.
