Ecobee Smart Thermostat vs Ecobee 4 – Check Which One Is Best & Why?

Ecobee Smart Thermostat & Ecobee4 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Ecobee Smart Thermostat rather than the Ecobee4.

Why Do I Recommend The Ecobee Smart Thermostat?

  • The Ecobee Smart Thermostat features a faster quad-core processor for quicker menu navigation, faster app response, and smoother touchscreen interaction, whereas the Ecobee4 uses a slower dual-core processor.
  • Ecobee Smart Thermostat comes with dual-band Wi-Fi (2.4 GHz + 5 GHz) for more reliable connectivity, faster network performance, and fewer signal dropouts, while the Ecobee4 supports only 2.4 GHz Wi-Fi.
  • It has a glass touchscreen for improved durability and a more premium, responsive surface when adjusting settings, whereas the Ecobee4 uses a less durable plastic display.
  • The Ecobee Smart Thermostat supports Siri voice control through Apple HomeKit for hands-free commands directly from the wall and seamless iOS ecosystem integration, while the Ecobee4 supports HomeKit automation but lacks Siri voice interaction.
  • Ecobee Smart Thermostat includes an upgraded far-field microphone array for better voice pickup from across the room and more accurate recognition of commands, compared to the Ecobee4’s standard microphone setup.
  • It features an enhanced built-in speaker for clearer voice responses, alarms, and supported streaming audio playback, whereas the Ecobee4 uses a basic speaker with limited clarity and function.
  • The Ecobee Smart Thermostat supports newer SmartSensors for improved occupancy detection and extended wireless range to maintain room comfort more accurately, while the Ecobee4 uses older Room Sensors with more limited performance.
  • Ecobee Smart Thermostat includes improved energy-efficient hardware to help reduce overall power consumption and lower long-term operating costs, whereas the Ecobee4 uses older internal components that are less efficient.

Maybe the Ecobee4 can make you comfortable because it’s a little bit cheaper than the Ecobee Smart Thermostat. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
