What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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, 2 lab-tested.)
Praised: Intuitive, responsive touchscreen and easy-to-use app/interface; Fast, DIY-friendly installation guided by the app; Supports remote room sensors for whole-home temperature averaging.
Flagged: C-wire required; Remote room sensors not included (~$40 each); No Apple HomeKit support.
