⚠️ A note on this review. Stelpro hasn’t been part of our hands-on testing yet, and reliable third-party spec sheets are harder to find for this brand than for Mysa or Sinopé. Where we’re confident, we say so. Where we’re not, we tell you to verify directly with Stelpro rather than guess. That’s the standard we hold every review on this site to, and it applies here above all.

Stelpro is a Quebec-based manufacturer of line-voltage and baseboard heating thermostats, commonly mentioned in the same breath as Mysa and Sinopé for homeowners with electric baseboard, convector, or in-floor heating. This review covers what’s established about the brand and positions it against its two better-documented competitors, without inventing prices, specs, or warranty terms we can’t confirm.

Verdict & Who It’s For

Stelpro is worth a look if:
– You have electric baseboard, convector, or radiant/in-floor heating and are already comparing Mysa and Sinopé
– You want a Quebec-made option and prefer to buy from a manufacturer with a long history in electric heating hardware (Stelpro has made line-voltage thermostats, smart and non-smart, for years)
– You’re comfortable doing your own due diligence on current app support and connectivity before purchasing

We’re not issuing a bolded “buy this” recommendation in this review, unlike our other comparisons. Stelpro’s current smart lineup, app ecosystem, and Wi-Fi/Zigbee specifics aren’t verified well enough on our end to responsibly rank it against Mysa or Sinopé feature-for-feature. Verify current model numbers, wattage ratings, and app ecosystem directly on Stelpro’s own site before buying.

Who Stelpro Is

Stelpro is a Quebec-based manufacturer with a long-standing presence in the electric heating hardware space: baseboard heaters, convectors, and the thermostats that control them. Like Sinopé, it’s a Quebec company operating in a market where electric baseboard and convector heating is far more common than in most of Canada and the US, thanks to relatively low electricity rates in the province.

The brand is positioned alongside Mysa and Sinopé as a line-voltage thermostat option for homeowners with electric heat rather than a central forced-air furnace. Beyond that positioning, we don’t have verified specifics on Stelpro’s current smart-thermostat model lineup to report with confidence. Check Stelpro’s own site for its current product range.

What It’s Built For

Line-voltage thermostats like Stelpro’s are designed to control 120V/240V electric heating loads directly: baseboard heaters, convectors, and in some cases in-floor/radiant systems. This hardware differs from the low-voltage thermostats (ecobee, Nest, Honeywell) that control central forced-air furnaces, and it’s the same category Mysa and Sinopé compete in.

Stelpro’s smart Wi-Fi models are commonly compared to Mysa and Sinopé for 2-wire baseboard compatibility, a detail that matters because not every line-voltage smart thermostat supports 2-wire setups (Mysa’s V2, for example, requires a neutral or second live wire, i.e., a 4-wire setup, while Sinopé offers both 2-wire and 4-wire models depending on the model line). Where exactly Stelpro’s current lineup falls on 2-wire vs. 4-wire support, and what wattage ratings it supports, is something we’d rather have you confirm directly with Stelpro than guess at here.

If you’re not sure which wiring category your baseboard heaters fall into, see Best Smart Thermostats for Electric Baseboard Heating in Canada for a broader rundown of baseboard compatibility before narrowing down to a specific brand.

Wi-Fi and App Basics

This is the section where we’re being most careful. We don’t have confirmed details on Stelpro’s current app name, whether its Wi-Fi models connect directly or require a separate hub, or which smart home ecosystems (Alexa, Google Home, Apple HomeKit) are supported on its current lineup.

What we can say: Mysa and Sinopé, the two most-documented line-voltage brands on this site, take different approaches here. Mysa connects directly to Wi-Fi with no hub required and is the only baseboard thermostat with native Apple HomeKit support. Sinopé’s Wi-Fi models also connect directly, while its Zigbee models require a Neviweb hub and don’t support Apple HomeKit at all, but do connect to Hydro-Québec’s Hilo demand-response platform.

Where Stelpro lands on hub requirements, HomeKit support, and app polish is unclear to us right now. Please verify current app and connectivity options directly with Stelpro before assuming it matches either competitor’s approach.

How It Compares to Mysa and Sinopé

We can position Stelpro without pretending to know specs we don’t have:

  • Market position: All three are line-voltage/baseboard specialists serving the same core use case: electric heat that ecobee, Nest, and Honeywell can’t control.
  • Regional footprint: Stelpro and Sinopé are both Quebec-based, which matters if buying Canadian-made hardware or supporting a Quebec company is a priority for you.
  • Documentation: Mysa and Sinopé both have well-documented Wi-Fi specs, wattage ratings, and app ecosystems that we’ve covered in detail elsewhere on this site. Stelpro’s equivalent details are harder to pin down from our research, which is why this review leads with hedging rather than a confident recommendation.
  • HomeKit: Mysa is the only baseboard/line-voltage thermostat we can confirm has native Apple HomeKit support. We can’t confirm one way or the other for Stelpro. Check directly.

Where to Buy / Rebate Eligibility Caveats

Line-voltage and baseboard thermostat rebate eligibility is inconsistent across Canadian provinces and utilities. The same caveat that applies to Mysa and Sinopé elsewhere on this site applies here too. Some provincial and utility rebate programs focus on central forced-air smart thermostats and either exclude line-voltage models entirely or apply narrower eligibility rules to them.

Before buying a Stelpro thermostat with a rebate in mind:
– Check whether your utility or province’s program explicitly lists line-voltage/baseboard thermostats as eligible
– Confirm whether Stelpro’s specific model numbers appear on any qualifying list. ENERGY STAR certification status for Stelpro’s current lineup is something we’d ask you to verify directly rather than assume
– Don’t assume eligibility just because Mysa or Sinopé qualifies in your area: program lists are model-specific

As for where to buy, availability for line-voltage brands like Stelpro tends to run through electrical supply retailers and hardware chains rather than the same big-box channels as ecobee or Nest. Verify current retail availability directly with Stelpro.
