Full Smart Thermostats comparison in 2026

Updated October 2026
Data from Amazon and official Google site.
2026 verdict
For a Google home with a bedroom that never feels right, the Nest Learning Thermostat (4th gen) is the better Nest, since it ships with a temperature sensor and learns your schedule on its own.

It also adds Matter, which is how it reaches Apple Home, a System Health Monitor that watches the heating and cooling system, schedule suggestions, a sharper 2.7 inch 600 x 600 display, a trim plate in the box and a two-year warranty against one, and owners rate it higher. The Nest Thermostat is the budget member of the family and still covers the basics well: presence, occupancy and ambient light sensing, an eco mode driven by phone location, Google Home, Alexa, Apple Home and SmartThings support, dual-band Wi-Fi and four colours. Both need the Google Home app and neither supports UK or EU heating systems. Buy the Nest Learning Thermostat (4th gen) for hands-off learning and multi-room comfort, and the Nest Thermostat if saving money on a simple swap is the goal.

What the differences mean

Learning and scheduling

The Nest Learning Thermostat (4th gen) builds a schedule by itself from the temperatures you set and suggests tweaks to save energy. The Nest Thermostat is set up with a guided manual schedule in the Google Home app, backed by its eco mode.

Room sensor

A Nest temperature sensor comes with the Nest Learning Thermostat (4th gen), and it can follow that sensor at chosen times of day, for example the bedroom at night. The Nest Thermostat supports no external sensors.

Matter and Apple Home

Both appear in Apple Home, but the Nest Learning Thermostat (4th gen) is the one with Matter, which is also the route it uses into Apple Home. Its bundled sensor stays in the Google Home app.

Display

The Learning model has a 2.7 inch 600 x 600 display controlled by its rotating ring. The Nest Thermostat has a 2.4 inch 240 x 320 screen controlled by a touch strip, which owners find less intuitive.

System health and warranty

Only the Nest Learning Thermostat (4th gen) has a System Health Monitor that can warn about heating and cooling problems early. It is also covered for two years, against one for the Nest Thermostat, and includes a trim plate.

Which one to buy if

What owners say

Owners of both Nests report the same core wins: pre-heating or pre-cooling from the phone before getting home, an away mode that uses presence to stop heating an empty house, and monthly reports that back up the savings. Both groups also share the same complaints, a C-wire that turns out to be necessary and control that now lives only in the Google Home app. Nest Learning Thermostat (4th gen) owners single out a large, animated display they call a real upgrade, learning that adjusts without any manual schedule and an included sensor that lets them favour the rooms they use, especially at night; some found the 4th gen refused to power on without a C-wire where their 3rd gen worked. Nest Thermostat owners talk more about value and rebates, and complain about an over-eager eco mode and a touch strip that feels less premium than the Learning model's ring.

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
