Sinopé TH1124WF vs Mysa V2: Electric Baseboard Thermostats in Canada
A practical comparison of Sinopé TH1124WF and Mysa V2 for Canadian line-voltage heating, including load, wiring, room-by-room cost and installation checks.
The short answer
Both are credible line-voltage thermostats. Sinopé TH1124WF publishes a 4,000 W limit at 240 V and fits naturally into Neviweb; Mysa V2 publishes 3,800 W at 240 V and emphasizes its touchscreen, humidity sensor and broad platform support. The safe winner is the one whose voltage, total heater load and wall-box conductors match first.
A home with electric baseboards or compatible convectors, one thermostat per heating zone and a clear electrical label for every controlled heater.
Central HVAC, an unknown load, incompatible fan-forced heating or a wall box whose wiring has not been identified.
Quebec homes often use several independent 240 V zones. Budget by thermostat count, not by house: automating eight rooms means buying and installing eight compatible controls.
Before shopping
Five checks that eliminate the wrong choices
Complete these checks in order. One physical or electrical incompatibility matters more than ten app features.
- 01
Photograph the current thermostat wiring before disconnecting anything and note whether the circuit is 120, 208 or 240 V.
- 02
Add the wattage of every baseboard or convector controlled by that single thermostat.
- 03
Check the heater type explicitly; a line-voltage thermostat is not automatically compatible with every fan-forced unit.
- 04
Test 2.4 GHz Wi-Fi at the wall and decide whether Apple Home, Google Home, Alexa or Neviweb matters.
- 05
Count every heating zone and obtain an installation quote before comparing the apparent price of one thermostat.
Useful comparison
The differences that can actually change the purchase
This is not a feature-score contest. An electrical mismatch ends the comparison immediately; interface and ecosystem preferences matter only after compatibility is established.
| Decision point | Sinopé TH1124WF | Mysa V2 |
|---|---|---|
| Published maximum at 240 V | 4,000 W | 3,800 W |
| Network | 2.4 GHz Wi-Fi | Wi-Fi; verify wall-box wiring |
| Distinctive value | Neviweb and Quebec-oriented electric-heating range | Touch controls, humidity sensing and app-based scheduling |
| Start here when | The 4,000 W limit or Neviweb ecosystem is decisive | The wiring fits and display or humidity data matters |
Action plan
A room-by-room plan that prevents an expensive redo
Inventory the zones
Create one line per thermostat: room, voltage, total watts, heater type, wiring photo and Wi-Fi quality.
Pilot one representative room
Choose a commonly occupied room whose load is comfortably below the limit. Validate comfort, schedules and connectivity before standardizing the whole house.
Expand by identical circuit type
Group only zones that share the same verified electrical conditions. Keep an electrician in the loop for uncertain conductors or mixed heating loads.
Your situation changes the answer
Three concrete scenarios
One 240 V baseboard zone close to 4,000 W
Check Sinopé TH1124WF firstIts published 240 V ceiling is 200 W higher, but the exact load and heater type must still be confirmed.
You want a visible touchscreen and humidity reading
Check Mysa V2 firstThose are explicit strengths once the electrical installation is compatible.
Eight or more independent rooms
Pilot, quote and expand in stagesThe full cost is the unit count plus installation; a one-room price hides the real project.

FAQ
Common questions before buying
Can a Nest or ecobee replace a baseboard thermostat?
Not by default. Most central-HVAC thermostats use low-voltage control, while electric baseboards commonly use line voltage. Verify the exact heating system and wiring rather than relying on the thermostat brand.
How do I calculate the heater load?
Use the wattage on each heater label and add every unit controlled by the same thermostat. Sinopé also publishes a 240 V estimate of about 250 W per foot when the label cannot be read; treat it as an estimate, not a substitute for electrical verification.
Should every room use the same brand?
One ecosystem simplifies schedules and support, but electrical compatibility comes first. Do not force one model into a zone that exceeds its load or uses an unsupported heater.
Can I install it myself?
These controls switch line voltage. Follow local electrical rules and use a qualified electrician whenever the conductors, breaker, load or heater type are uncertain.

Build the budget room by room
An evening-only bedroom and an all-day occupied room offer different scheduling opportunities. Write three columns: current schedule, a change you would actually accept and installed cost. Start with rooms where the schedule can genuinely change; replacing every thermostat at once is not a requirement.
To assess savings, retain kWh, dates, outdoor temperatures and occupancy changes. A smaller bill during milder weather does not isolate the thermostat’s effect. Comfort, remote control and savings are three distinct benefits: value each according to your use.
Three checks that can rule out a thermostat before price
Mysa’s current V2 page specifies a 250 W minimum load and says manual temperature control still works without Wi-Fi, while smart functions are lost. That does not validate every stored schedule during an outage. Its page advertises five-year coverage; read the applicable warranty terms for the actual purchase.
Sinopé’s linked family page currently presents the 3,000 W TH1123WF for sale, even though it also contains TH1124WF dimensions. Do not use that page’s price or stock badge as an offer for the 4,000 W TH1124WF. Match the model on the seller’s invoice and on the device; those load ratings are not interchangeable.
The TH1124WF installation sheet confirms 4,000 W maximum at 240 V for a resistive load. Its minimum is 500 W for baseboard/convector/radiant-ceiling heating, or 1,000 W for a fan-forced convector, at 240 V. A small room can therefore fail the minimum even when it is well below the maximum. Sinopé requires installation by a certified electrician.

Sinopé: the stored schedule survives an Internet outage
Sinopé’s support article explicitly includes TH1124WF: schedules are stored in the thermostat and continue without Internet or Wi-Fi. After a power outage, settings are retained and operation resumes when power returns. This confirms the saved heating schedule; it does not make remote control or cloud-based features available during an outage.
That matters in a cottage with unreliable connectivity: a previously programmed TH1124WF has a documented local schedule. For Mysa V2, the product page confirms manual control without Wi-Fi; that narrower statement should not be treated as proof that every smart feature behaves identically. Compare the exact function you need, not just whether the display stays on.

Price the zones, then calculate a break-even point
Example assumptions: six thermostats at C$160 cost C$960 before tax and installation. At an actually verified C$120 annual reduction in heating cost, hardware alone takes eight years to recover. If the change saves only C$60, that becomes sixteen years. Installation lengthens both periods. These are scenario calculations, not today’s prices or a promised saving.
