Mysa and ecobee solve different heating problems. The comparison only makes sense once you know what type of heating system you have.

The Core Difference: Voltage

ecobee is a low-voltage (24V) thermostat. It works with gas furnaces, central air conditioners, heat pumps, and boilers, systems where the thermostat is a signaling device sending small control currents.

Mysa V2 is a line-voltage (120V/240V) thermostat. It works with electric baseboard heaters, fan-forced heaters, and electric convectors, systems where the thermostat carries the full power current to the heating element.

These are different categories. Installing an ecobee on a baseboard heater circuit is not possible and would be dangerous. Installing Mysa on a gas furnace is wrong too.

When You Need Mysa (Not ecobee)

  • Your home heats with electric baseboard heaters
  • You have fan-forced electric heaters mounted on walls or ceilings
  • Your heater plugs into the wall at 120V or runs on a dedicated 240V circuit

Signs of baseboard heating: Hard-mounted heaters under windows with a thermostat that has thick wires (12 or 14 gauge) and no G, Y, or C terminals, only two or four heavy wires.

Mysa V2 handles both 120V and 240V in one model. It supports Apple HomeKit, connects to Wi-Fi, and includes freeze protection: the features you want from a smart thermostat, built for line-voltage systems.

When You Need ecobee (Not Mysa)

  • Your home heats with a gas or oil furnace
  • You have central air conditioning (ducted AC)
  • You have a heat pump (ducted or packaged)
  • Your thermostat wiring includes thin, colour-coded signal wires (18 or 20 gauge) with terminal labels like R, C, W, Y, G

ecobee Enhanced covers most Canadian and US central HVAC homes. ecobee Premium adds a room sensor and better heat pump controls. Both require a C-wire or the included Power Extender Kit.

Can You Use Both in One Home?

Yes, and it’s common in mixed heating homes.

Typical scenario: A Canadian home where the main living area and bedrooms are heated by a gas furnace (ecobee), but an older addition or garage suite has electric baseboard heating (Mysa). Both work on their own; there’s no integration between the two platforms.

Another scenario: A home that installs a central heat pump for main areas while keeping baseboard heaters in bathrooms or spare rooms as supplemental heat. ecobee controls the heat pump; Mysa controls the baseboard zones.

Both apps (ecobee and Mysa) are separate apps on your phone. There’s no combined dashboard, but both integrate with Apple HomeKit on their own, and HomeKit provides a unified view through the Home app.

The Real Mysa vs ecobee Comparison (Same System Type)

In the rare case where a home has a system type that could go either way (some mini-splits, for example):

Mysa V2 ecobee Enhanced
System type Line-voltage (120V/240V) Low-voltage (24V)
HomeKit Yes Yes
Room sensors No Add-on (~$69/each)
C-wire needed No No (PEK)
Demand response PSE Flex (WA) Broad coverage
Warranty 2 years 3 years
Price (CAD) ~$119–129 ~$229
Hub required No No

Frequently Asked Questions

Should I buy Mysa or ecobee?
Your heating system determines the answer, not preference. Electric baseboard heating → Mysa V2. Gas furnace, central AC, or heat pump → ecobee. They’re not interchangeable.

Can Mysa control a gas furnace?
No, Mysa is a line-voltage thermostat designed for electric baseboard heating. You can’t use it with gas furnaces or any 24V low-voltage HVAC system.

Can ecobee control electric baseboard heaters?
No, ecobee is a low-voltage (24V) thermostat. Electric baseboard heaters run on line voltage (120V or 240V). Installing a low-voltage thermostat on a line-voltage circuit is a safety hazard.

What if I have both baseboard and a furnace?
Use Mysa for the baseboard zones and ecobee for the furnace/central system. They run on their own but both integrate with Apple HomeKit, and the Home app shows all devices together.

Is Mysa or ecobee better for Canadian homes?
Both are Canadian companies (Mysa from Newfoundland, ecobee from Toronto). What matters is which heating system you have, not which company is “better.”
