The short version: Before you go shopping for this, a correction. Cadet is a widely stocked electric-heat brand at Home Depot Canada, but it doesn’t sell a first-party Wi-Fi app-connected thermostat as a headline product. Cadet’s own published guidance actually recommends against pairing generic smart/Wi-Fi thermostats with its baseboard heaters, citing power-relay reliability problems, and points customers to its non-connected TEP Series electronic programmable thermostat instead. If you want real Wi-Fi control on Cadet baseboard heat, you’re looking at a compatible third-party thermostat, not a Cadet-branded app.

Who It’s For

Cadet baseboard and wall heaters show up in Canadian homes, particularly older builds and rentals. If you already have Cadet heaters and want app-based control, this review is here to save you the search: look at Mysa or Sinopé, both explicitly built for baseboard retrofits, rather than a Cadet-branded smart thermostat that we could not confirm exists as a mainstream product.

What Cadet Actually Sells

Cadet’s confirmed line-voltage thermostat lineup is the TEP Series (electronic, programmable, no app) plus older mechanical models. According to Cadet’s own published article, the company tested pairing Wi-Fi thermostats (including Lyric and Nest) with its heaters using standard relays and found the relays didn’t deliver reliable long-term power, with a risk of draining the connected thermostat’s internal battery. Cadet’s own stated position is that its electronic programmable thermostat is the better match for its heaters than a generic smart Wi-Fi one.

We’re flagging this directly because it’s a useful, specific finding, and because it means the “Cadet Wi-Fi Smart Thermostat” this page was originally scoped to review isn’t a confirmed retail product as of this writing.

Setup & Compatibility

The TEP Series wires directly into the baseboard or wall-heater circuit: no C-wire, no hub, no app. If you want Wi-Fi control anyway, look for a third-party thermostat explicitly rated for your Cadet heater’s amperage and wiring configuration (single-pole vs. double-pole, 2-wire vs. 4-wire), rather than assuming universal compatibility. Mysa publishes compatibility guidance for baseboard and convector heaters that’s worth checking against your specific Cadet model.

Price & Value

Cadet Electronic Thermostat (TEP Series)
Price (CAD) $80–$150
Wi-Fi/app Not confirmed as a Cadet-branded feature
Retailers Home Depot, Amazon.ca

In line with other electric-heat brands’ programmable (non-smart) thermostats. Budget for a separate compatible smart thermostat if app control is the goal.

Pros & Cons

Pros:
– Widely stocked at Home Depot Canada and Amazon.ca
– TEP Series is a straightforward, well-documented upgrade from a mechanical dial thermostat
– Cadet’s own published compatibility guidance is unusually direct and useful

Cons:
– No confirmed first-party Wi-Fi/app-connected thermostat
– Cadet itself recommends against pairing generic smart thermostats with its heaters
– App control requires researching third-party compatibility yourself
– No confirmed rebate eligibility on the non-connected TEP line, since it lacks scheduling/demand-response features most programs require

The Recommendation

Buy the Cadet TEP Series if you want a reliable programmable (non-Wi-Fi) upgrade for Cadet baseboard heat.

Look at Mysa or Sinopé instead if Wi-Fi control matters, after confirming amperage and wiring compatibility with your specific Cadet heater. See Mysa vs Sinopé: Which Line-Voltage Smart Thermostat Wins?

Frequently Asked Questions

Does Cadet make a Wi-Fi smart thermostat?
We could not confirm a mainstream first-party Wi-Fi app-connected Cadet thermostat sold in Canada. Cadet’s own guidance recommends its non-connected TEP Series over generic smart/Wi-Fi options.

Can I use Mysa or Sinopé with a Cadet baseboard heater?
Likely, but confirm amperage and wiring compatibility (single-pole/double-pole, 2-wire/4-wire) with the specific thermostat before buying. Both publish compatibility guidance for baseboard retrofits.

Does the Cadet TEP Series qualify for Canadian rebates?
We don’t have this confirmed, and non-connected programmable thermostats generally don’t qualify for smart-thermostat rebate programs. Check your provincial program’s qualifying list. See Smart Thermostat Rebates in Canada by Province.

Why doesn’t this review look like your other smart thermostat reviews?
Because the product this page was originally scoped to cover, a “Cadet Wi-Fi Smart Thermostat,” isn’t a confirmed retail product. We’re telling you what Cadet actually sells and what the company itself says about pairing smart thermostats with its heaters, rather than describing features we can’t verify.
