The short version: Mysa is the best-documented smart thermostat for Canadian electric baseboard, convector, and fan-forced heat. It handles 120V and 240V circuits in one device, connects to Wi-Fi with no hub, and is the only baseboard thermostat with native Apple HomeKit support. For most Canadian homes with baseboard heat, this is the default recommendation.

Who Makes Mysa, and Why It Matters

Mysa is built by Empowered Homes, a company founded in 2016 and based in St. John’s, Newfoundland. Newfoundland and Labrador heats almost entirely with electric baseboard, and Mysa was designed around that reality rather than adapted from a central-HVAC thermostat built for a furnace. That matters for a few practical reasons:

  • Warranty claims and customer support run through a Canadian company with Canadian support hours
  • Mysa has appeared on the qualifying list for takeCHARGE, Newfoundland and Labrador’s utility rebate program, making it one of the more consistently rebate-eligible baseboard thermostats in Canada
  • The product’s feature set (freeze protection, per-room zoning) reflects genuine baseboard-heating use cases rather than being bolted on

Who It’s For

Mysa only controls line-voltage electric resistance heat: baseboard heaters, electric convectors, and in-wall fan-forced heaters. It does not work with a gas furnace, heat pump, or central forced-air system — for those, see our ecobee or Nest reviews.

If your home (or cottage) has individual baseboard heaters in each room rather than one furnace and a duct system, this is the category you’re shopping in.

Design & Build

The thermostat is a compact white unit with a small circular LED display showing set and current temperature. It’s deliberately understated, more like a modern light switch than a gadget. A touch ring around the display lets you adjust temperature by hand without opening the app.

Build quality is solid. The mounting plate installs first, and the thermostat snaps onto it magnetically. The LED display reads clearly up close, though it can be harder to see from across a bright room.

Setup & Compatibility

Voltage: The current hardware handles both 120V and 240V baseboard circuits in a single device — you pick the voltage in the app during setup. This is a real practical advantage over Sinopé, which sells separate models for 120V and 240V. Maximum load is roughly 3,600–3,800W (about 16A), which covers the great majority of individual baseboard and convector circuits.

Wiring: Mysa requires 4 wires in the thermostat box. Older Canadian homes, especially pre-1980s builds, often have 2-wire baseboard circuits — if that’s you, Mysa isn’t compatible and Sinopé (which supports 2-wire) is the better-fitting option. Pull the faceplate off your existing thermostat and count the wires before ordering.

No C-wire, no hub: Mysa connects straight to your home’s 2.4GHz Wi-Fi. No bridge or gateway required, unlike Sinopé’s Zigbee lineup.

Installation: This is line-voltage electrical work. Turn off the breaker, confirm power is dead with a voltage tester, and follow the app’s step-by-step wiring diagram matched to your setup. If you’re unsure about your wiring, find aluminum wiring in the box, or live somewhere that requires a permit or licensed electrician for thermostat replacement, hire one.

App & Ecosystem

The Mysa app (iOS and Android) covers weekly scheduling with per-day customization, geofencing (heat drops when your phone leaves a defined radius and resumes when you’re back), energy reporting in kWh with cost estimates, and freeze protection — a minimum-temperature floor that holds even in “off” or “away” mode, which matters for a Canadian cottage you don’t want to freeze pipes in over winter.

Smart home support:
– Apple HomeKit: Full native support — the standout feature in this category. No other widely sold Canadian baseboard thermostat offers it.
– Google Assistant: Supported
– Amazon Alexa: Supported
– Samsung SmartThings: Supported

Most baseboard homes run several Mysa units, one per room. The app’s multi-zone dashboard shows all of them on one screen with independent schedules.

Buyer Feedback: What We Found

Retailer and installer feedback on Mysa’s baseboard line skews positive on the basics: it’s frequently described as one of the only smart thermostats that genuinely works with line-voltage baseboard heat, with clear installation instructions and responsive support for wiring questions. The most consistent complaint we found relates to Alexa pairing specifically — a handful of buyers describe the Alexa-skill linking flow as less smooth than setup through Mysa’s own app. We did not find evidence of widespread Wi-Fi reliability complaints at the scale sometimes reported for cheaper generic baseboard thermostats sold on Amazon.

Energy Savings and Demand Response

Electric baseboard heat is 100% efficient at converting electricity to heat — a smart thermostat doesn’t change that efficiency, it saves money by running the heater less. Geofencing cuts daytime runtime in homes that are empty during work hours, and per-room control lets you hold unoccupied rooms several degrees cooler while keeping living spaces comfortable, something a single central thermostat can’t do.

Hydro-Québec’s Hilo demand-response platform currently supports Sinopé’s Zigbee thermostats, not Mysa. Canadian demand-response participation for baseboard thermostats generally is less developed outside Quebec.

Rebate Eligibility

Mysa is ENERGY STAR certified. It has appeared on the qualifying list for takeCHARGE (Newfoundland and Labrador), a natural fit given the company’s origins there. Eligibility on other provincial and utility programs varies by year — many Canadian rebate programs are still written primarily for central-HVAC thermostats, so baseboard thermostat eligibility overall is less consistent than for an ecobee or Nest.

Price & Value

Mysa Baseboard/Convector
Price (CAD) ~$130–180 per thermostat
Warranty 2 years
Subscription None
Hub required No

For a whole-home baseboard setup — say six thermostats — expect roughly $780–1,080 before installation. Compare that to Sinopé’s Zigbee lineup, which runs cheaper per unit once you factor in the shared hub across multiple thermostats.

Pros & Cons

Pros:
– Handles 120V and 240V in one model
– Apple HomeKit support — unique among Canadian baseboard thermostats
– No hub required
– Real energy reporting and freeze protection, useful for cottages
– ENERGY STAR certified; on takeCHARGE’s qualifying list
– Canadian company with Canadian support

Cons:
– Requires 4-wire wiring, incompatible with older 2-wire circuits
– Higher per-unit price than Sinopé for multi-zone installs
– No Zigbee/Hilo integration for Hydro-Québec demand response
– A handful of buyers report friction pairing specifically with Alexa

The Recommendation

Buy Mysa if you have 4-wire baseboard, convector, or fan-forced circuits and want the best all-around feature set, including Apple HomeKit. It’s the right call for cottage owners who want freeze protection and remote monitoring, and for Newfoundland and Labrador homeowners eligible for the takeCHARGE rebate.

Frequently Asked Questions

Does Mysa work with 240V baseboard heaters?
Yes. The current model handles both 120V and 240V circuits, selected in the app during setup, with a maximum load around 3,600–3,800W.

Does Mysa require a hub?
No. It connects directly to your home’s 2.4GHz Wi-Fi router.

Does Mysa support Apple HomeKit?
Yes, and it’s one of the only line-voltage baseboard thermostats in Canada that does.

How many wires does Mysa need?
Four wires in the thermostat box. If your box has only two wires, Mysa isn’t compatible — look at Sinopé instead.

Is Mysa eligible for Canadian rebates?
It’s ENERGY STAR certified and has appeared on takeCHARGE’s (Newfoundland and Labrador) qualifying list. Eligibility on other provincial programs varies by year — check with your utility before buying.

How does Mysa compare to Sinopé?
Mysa wins on HomeKit support and handling both voltages in one model. Sinopé wins on 2-wire compatibility, Hilo integration for Hydro-Québec customers, and lower per-unit price across multiple zones. See Mysa vs Sinopé: Which Line-Voltage Smart Thermostat Wins?
