Ranked #3 in Best Smart Thermostats

Ecobee Smart Thermostat Essential

4.1

6 sources$139.99as of Aug 1

Alexa and Google Assistant both work with the Ecobee Smart Thermostat Essential, and its detailed energy reports help trim heating and cooling costs. PCMag's John R. Delaney praised the easy installation and clean touchscreen interface, while Tom's Guide questioned whether the higher price is justified for budget-conscious buyers. As the stripped-down model in ecobee's lineup, it ships without a SmartSensor, so room-by-room occupancy sensing requires buying one separately. Tech-savvy homeowners chasing energy efficiency and smart-home automation are the fit; tight budgets should consider alternatives.

Strengths

— Works well with Alexa and Google Assistant for voice control
— Provides detailed energy usage reports and insights
— Supports add-on ecobee SmartSensors for room-by-room comfort

Watch-outs

— Higher price point compared to basic thermostats
— Some users report occasional connectivity issues with smart home hubs
— Occupancy/room sensing requires separately sold SmartSensors

How they stack up

Ecobee Smart Thermostat Essential

The Ecobee Smart Thermostat Essential sets itself apart with broad smart-home support and optional add-on SmartSensors for room-by-room temperature and occupancy — sensing the Amazon and Sensi models can't do without extra hardware. It costs more than the Sensi Touch 2 and lacks the automatic learning of the Nest Learning Thermostat (4th Gen), but it's a strong middle-ground choice for multi-room homes.

Sensi Touch 2 Smart Thermostat

The Sensi Touch 2 wins on broad HVAC compatibility and a clear color touchscreen at a fair price, but it lacks the adaptive learning of the Google Nest Learning Thermostat (4th Gen) and the add-on SmartSensor support of the Ecobee Smart Thermostat Essential. It's best for users who value dependable scheduling and wide system compatibility over advanced automation.
