Ecobee vs Mysa: Key Specs Compared
System Compatibility
Ecobee is designed for central HVAC systems, claiming compatibility with 95% of such setups. It uses a Power Extender Kit to handle homes without a C-wire. Mysa serves a different niche entirely. It is built for line-voltage electric baseboard, fan-forced, wall, and convector heaters. It handles 120V or 240V power, supporting up to 1,900W or 3,800W respectively. It replaces single-pole and double-pole thermostats for electric heat. It will not work on 24V furnaces or central heat pumps. You must choose based on your heating hardware. Ecobee fits central air and heat. Mysa fits electric baseboards.
Smart Home Compatibility
Ecobee supports Siri and Alexa built-in. It allows voice control and can stream audio through its speaker. It requires an Apple home hub for Siri. Mysa supports Apple HomeKit, Alexa, and Google Home. This gives you broader voice assistant options without needing a separate hub for Apple users. Mysa also offers local control via on-device buttons. Ecobee focuses on its own ecosystem with built-in speakers and sensors. If you use Google Home, Mysa is the clear choice. If you prefer Siri, Ecobee integrates natively. Both allow remote control via their respective apps.
Wiring Requirement
Ecobee includes a Power Extender Kit for homes lacking a C-wire. This simplifies installation for many central HVAC systems. It also provides a trim kit for a clean look. Mysa requires four wires, including a neutral or a second live wire. It will not work on a two-wire switch loop. You must check your wiring before ordering. Mysa provides a guided DIY install in the app but warns about high-voltage wiring safety. Ecobee’s C-wire solution is more flexible for older homes. Mysa’s requirement is stricter due to its line-voltage design. You need to verify your existing wires match the device.
Sensor Support
Ecobee includes a SmartSensor to detect occupancy in specific rooms. It adjusts temperature based on where you are, rather than just the hallway. It also has a built-in air quality monitor that alerts you to poor air and reminds you to change filters. It can detect smoke alarm sounds. Mysa does not list any built-in sensors or remote sensor support in the provided data. It relies on scheduling and geofencing for energy savings. Ecobee offers more environmental monitoring and room-specific comfort control. Mysa focuses on basic temperature regulation for electric heat.
Warranty
Ecobee provides an industry-leading three-year warranty. This covers the Smart Thermostat Premium. Mysa offers a five-year limited warranty. This applies only to products sold directly by Mysa. Mysa also provides North American-based support seven days a week. Ecobee’s warranty is shorter but still robust. Mysa’s five-year term is longer for line-voltage units. If you buy directly from Mysa, you get extended coverage. Ecobee’s three years is standard for central thermostats. Both companies stand behind their hardware. The difference is two years in favor of Mysa.

You prefer no monthly subscription fees
Mysa includes scheduling, remote control, voice control, and geofencing in the free app without requiring a subscription.
