The short version: Stelpro, a Quebec-based electric heating manufacturer, sells two separate Wi-Fi smart thermostat lines: Concerto for electric in-floor heating and Maestro for baseboard, convector, and fan heaters. Both connect directly to Wi-Fi without a hub. Retailer ratings for Maestro are mixed rather than uniformly strong, so this isn’t an automatic top pick over Mysa or Sinopé — it’s a reasonable option worth comparing on price and current reviews.

Who Makes Stelpro

Stelpro is a Quebec-based manufacturer with a long history in electric heating hardware — baseboard heaters, convectors, and the thermostats that control them — predating its move into Wi-Fi smart thermostats. Like Sinopé, it’s a Quebec company selling into a market where electric baseboard and floor heating are especially common, thanks to the province’s relatively low electricity rates.

Who It’s For

Both lines are line-voltage electric resistance thermostats — they don’t control a furnace, heat pump, or central air system.

  • Concerto is for electric in-floor (radiant) heating — mats or cables under tile, hardwood, or laminate.
  • Maestro is for electric baseboard heaters, convectors, and fan heaters.

If you have electric resistance heat and are already comparing Mysa and Sinopé, Stelpro is a third Quebec-rooted option worth putting in the same comparison.

Design & Build

Both lines share a similar rectangular thermostat housing with a backlit LCD display and physical buttons for setpoint adjustment without the app. Concerto units add a floor-sensor input and, on some models, on-screen energy monitoring.

Setup & Compatibility

Concerto (floor heating): Supports 120V, 208V, and 240V electric floor-heating systems, with a 15-foot floor sensor included. Offers floor-temperature control, ambient (room) control, or ambient control with a floor-temperature limit. Built-in Class A GFCI with test light — appropriate for bathroom installs. Setup runs through a five-step startup wizard in the app, and it’s compatible with floor sensors from other brands if you’re swapping an existing thermostat without replacing the sensor.

Maestro (baseboard/convector/fan heaters): Adds smart connectivity to Maestro-compatible line-voltage baseboards, convectors, and fan heaters, with room-by-room zone grouping and geofencing.

No hub required for either line — both connect directly to home Wi-Fi, unlike Sinopé’s Zigbee models.

Installation: Both are line-voltage electrical work. Turn off the breaker, verify power is off with a voltage tester, and follow the app’s wiring walkthrough. If you’re not confident with line-voltage wiring, or your province requires a licensed electrician for a thermostat swap, hire one.

App & Ecosystem

Concerto ships pre-programmed with four weekday and two weekend scheduling events you can customize. Maestro adds geofencing, adjusting temperature automatically based on your phone’s location. Both track energy consumption.

Smart home support: Alexa and Google Assistant, connected through IFTTT rather than a native integration on Maestro. Apple HomeKit is not supported on either line — Mysa remains the option to consider if HomeKit matters to you.

Buyer Feedback: What We Found

Feedback is genuinely mixed, and we’re not smoothing that over. Maestro’s retailer ratings vary sharply by platform: a strong 5-out-of-5 on Wayfair versus a notably weaker 2.9-out-of-5 across nine reviewers on RONA, a major Canadian retailer that carries the product. Some buyers describe reliability issues; others report it working as expected with no problems. We did not find a comparable volume of independent reviews specifically for Concerto. Given the spread in Maestro’s ratings, check current reviews on the specific retailer you’re buying from (RONA, Home Depot, Walmart.ca) rather than assuming consistency.

Rebate Eligibility

Line-voltage and baseboard/floor-heating thermostat rebate eligibility is inconsistent across Canadian provinces and utilities generally, and this applies to Stelpro as much as to Mysa or Sinopé. Confirm whether your utility or province’s program lists Stelpro’s specific model numbers as qualifying before buying with a rebate in mind — don’t assume eligibility just because a competing brand qualifies in your area.

Priced comparably to Mysa. Where Stelpro can win is in retailers like Walmart.ca and RONA where Mysa isn’t always stocked, and among buyers specifically comparing Quebec-made options against Sinopé and Mysa.

Pros & Cons

Pros:
– Two dedicated product lines matched to floor heating (Concerto) vs. baseboard/convector/fan heat (Maestro)
– No hub required, direct Wi-Fi connection
– Built-in Class A GFCI on Concerto, appropriate for bathroom floor-heating installs
– 3-year warranty
– Sold through Walmart.ca and RONA, retailers where Mysa/Sinopé aren’t always available

Cons:
– Retailer ratings for Maestro are inconsistent — some buyers report reliability problems, notably a sub-3-star average on RONA
– No native Apple HomeKit support on either line
– Alexa/Google Assistant integration runs through IFTTT rather than a direct connection
– Rebate eligibility not consistently confirmed across provincial programs

The Recommendation

Consider Stelpro Concerto for electric floor heating, and Maestro for baseboard/convector/fan heat, especially if you’re shopping at Walmart.ca or RONA and want a Quebec-made option. Check current retailer star ratings before buying given the mixed feedback we found for Maestro. If Apple HomeKit support or Hilo integration (for Hydro-Québec customers) matters more, Mysa or Sinopé are the better-documented defaults.

Frequently Asked Questions

What’s the difference between Stelpro Concerto and Maestro?
Concerto is built for electric in-floor heating with a floor sensor and floor-temperature control. Maestro is built for electric baseboard, convector, and fan heaters. They’re separate product lines under the same brand.

Do these thermostats need a hub?
No. Both connect directly to your home Wi-Fi, unlike Sinopé’s Zigbee models.

No. Neither Concerto nor Maestro supports HomeKit. Mysa is the option to consider if HomeKit is a requirement.

Are Stelpro thermostats reliable?
Reviews are mixed. Retailer ratings for Maestro range from strongly positive to notably weak depending on the platform (RONA specifically shows a low average from a small sample). Check current reviews on the retailer you’re buying from.

Is Stelpro eligible for Canadian utility rebates?
