## What reviewers say

**Amazon Smart Thermostat** — Three whitelisted outlets reviewed the ~$60 Amazon Smart Thermostat in 2021-2022 and all rate it the best-value smart thermostat. Tom's Guide and Reviewed/USA Today are hands-on reviews (Reviewed wired it to a test rig); TechRadar is a 'should I buy' buying-advice piece with no hands-on testing. None report any lab-measured numbers (all measured arrays empty). The one universal caveat is that the thermostat is Alexa-only. All nine quotes were verified as literal substrings of the fetched pages. (3 sourced reviews.)

**Sensi Touch 2 Smart Thermostat** — Three whitelisted testers (TechHive, Pro Tool Reviews, Reviewed) rate the Sensi Touch 2 among the best simple smart thermostats, praising its responsive touchscreen, easy app-guided installation (Pro Tool Reviews clocked ~10 minutes), and support for remote room sensors that average temperatures across the home. All three note it requires a C-wire. Reviewed lab-tested it on a simulated HVAC system with a NIST-calibrated thermometer but published no accuracy figure; its main criticism is the lack of machine learning at a premium price. (3 sourced reviews.)
