Smart Thermostats / Google
Google Nest Thermostat (2020)
Matter-certified and usually C-wire-free, but it does not learn and takes no sensors.
Overall score 6.6/10
Pros
- + Matter certification at $129.99 puts it in Apple Home, which no ecobee, Sensi or Amazon model here manages
- + Same Power Sharing wiring trick as the Learning Thermostat, so it usually installs without a C wire
- + Battery backup on two AAA cells — the Amazon, X2S and Sensi Touch 2 all go dark if 24V power drops
- + Cheapest way into the Google ecosystem with a real touch UI, at less than half the Learning Thermostat's list price
Cons
- − No remote sensor support at all — Google says outright it is not compatible with the Nest Temperature Sensor, so this is a one-room thermostat
- − It does not learn. Google gives it guided schedule setup instead, which is the single feature people think they are buying when they buy 'a Nest'
- − Google's spec page only claims single-stage conventional support; two-stage furnace owners should check compatibility before buying
- − No published humidifier, dehumidifier or ventilator terminals
- − 1-year warranty, against 2 on the Learning Thermostat and 3 on every ecobee here
Google Nest Thermostat (2020) review: what the specs say
Matter-certified and usually C-wire-free, but it does not learn and takes no sensors. At $129.99, Google's 2020 model sits in the middle of the range — the smart Thermostats we compare run from $79 to $259.99. It scores 6.6/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Smart Home Integration at 8.5/10 — matter, Apple Home, Alexa and Google support — and how much each one actually exposes. The weakest is Multi-Room Sensing at 1.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: no remote sensor support at all — Google says outright it is not compatible with the Nest Temperature Sensor, so this is a one-room thermostat; and it does not learn. Google gives it guided schedule setup instead, which is the single feature people think they are buying when they buy 'a Nest'. Every specification on this page comes from Google's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
