Ecobee Smart Thermostat Essential
#3
Best for: tech-savvy homeowners seeking occupancy detection
Ecobee Smart Thermostat Essential
from 5 sources$139.99as of Jun 7

The Ecobee Smart Thermostat Essential offers robust smart-home integration with Alexa and Google Assistant support, along with detailed energy reports that help users optimize heating and cooling costs. PCMag's John R. Delaney praised its ease of installation and clean touchscreen interface, though Tom's Guide noted that the device's higher price point may not justify its features for budget-conscious consumers. As the stripped-down model in ecobee's lineup, it ships without a SmartSensor, so room-by-room occupancy sensing requires buying one separately. This thermostat is ideal for tech-savvy homeowners seeking energy efficiency and smart-home automation, but those on tight budgets may want to consider alternatives.

Strengths
  • — Works well with Alexa and Google Assistant for voice control
  • — Provides detailed energy usage reports and insights
Watch-outs
  • — Higher price point compared to basic thermostats
  • — Some users report occasional connectivity issues with smart home hubs
