Sinopé or Mysa for electric baseboards: choose from the circuit, not the app
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 | Touchscreen, humidity sensing and polished app experience |
| 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.
