The short version: Dimplex has sold electric baseboard heaters in Canada for decades, and its current Wi-Fi control system, CONNEXT, replaces the older CONNEX system the company discontinued in 2022. Retailer reviews of CONNEX described difficult setup, sync failures, and units failing within a year, which is worth knowing even though it’s the older product. We couldn’t find a comparable independent review base for the current CONNEXT system, so treat this as a manufacturer-native option to evaluate carefully against Mysa, Sinopé, or Stelpro before buying.

Who It’s For

Dimplex is relevant to Canadian homeowners with electric baseboard, convector, or wall-heater setups, especially if you already have Dimplex-brand baseboards installed and want the manufacturer’s own app control layered on top. It’s a narrower fit than Mysa or Sinopé, both of which are designed to retrofit onto a broader range of existing baseboard hardware.

Design & Build

Dimplex’s smart system is built around a Wi-Fi hub or bridge that communicates with individual baseboard or wall-mounted controllers, rather than a single stand-alone thermostat unit. That means setup involves pairing a hub with multiple zone controllers rather than mounting one device and connecting it to Wi-Fi directly, a meaningfully different process than Mysa’s single-unit installation.

Setup & Compatibility

The connected system pairs with Dimplex’s own LPC and PC Linear baseboard series. It is not confirmed as a universal retrofit for other brands’ baseboard heaters, so if you have non-Dimplex heaters, check compatibility carefully or look at Mysa or Sinopé, both of which are designed to work across a wider range of existing baseboard and convector hardware in Canadian homes. No C-wire is required for the basic wiring, since it’s a line-voltage system, but the hub/bridge pairing adds a setup step that single-unit competitors don’t have.

App & Ecosystem

Dimplex discontinued the original CONNEX app and cloud service in June 2022, per the company’s own discontinuation FAQ. Reviews of that system (Home Depot, Walmart) described an awkward USB-based initial setup, an unintuitive interface, the need for a separate account per thermostat when running more than one, and a notable share of low-star ratings citing failures within six months to a year and unresolved Wi-Fi sync issues.

CONNEXT is the current-generation system that replaced CONNEX. We could not find enough independent Canadian reviews of CONNEXT specifically to say whether these problems were resolved. If you’re considering it, check the current CONNEXT app’s store rating and recent reviews, that will be more current and reliable than anything available on the discontinued predecessor.

Dimplex thermostats don’t carry Hilo or Neviweb compatibility the way Sinopé does, so if you’re specifically shopping for Hydro-Québec demand-response participation, Sinopé is the more established option.

Price & Value

Dimplex Smart Thermostat/Controller
Price (CAD) $150–$220
Ecosystem CONNEXT hub + Wi-Fi app
Retailers Home Depot, Amazon.ca, electrical supply houses

Comparable in price to Mysa and Stelpro’s Wi-Fi lines, with the added consideration that you’re buying into Dimplex-specific hardware for multi-zone control.

Pros & Cons

Pros:
– Long-established electric-heat manufacturer with wide Canadian retail availability
– Multi-zone app control is convenient for homes with several baseboard heaters
– Sold through Home Depot and electrical supply houses across Canada

Cons:
– Predecessor CONNEX system was discontinued in 2022 after reviews cited setup problems and short lifespans
– No confirmed independent review base for the current CONNEXT system
– Best suited to homes already using Dimplex-brand baseboard hardware
– No confirmed Hilo or Neviweb integration for Quebec demand-response programs

The Recommendation

Consider Dimplex CONNEXT if you already have Dimplex baseboard heaters and want manufacturer-native multi-zone control. Check the current app’s store reviews first given the rocky history of its CONNEX predecessor.

Consider Mysa or Sinopé instead if you want a single-unit thermostat with a stronger Canadian review trail, broader baseboard-brand compatibility, or (for Sinopé) Hilo demand-response participation. See Mysa vs Sinopé: Which Line-Voltage Smart Thermostat Wins?

Frequently Asked Questions

Is Dimplex CONNEX still supported in Canada?
No. Dimplex discontinued the CONNEX app and cloud service in June 2022. It has been replaced by CONNEXT.

Does Dimplex qualify for Canadian utility rebates?
We don’t have this confirmed for the current CONNEXT system. Check your provincial program’s qualifying list before assuming eligibility. See Smart Thermostat Rebates in Canada by Province.

Can I use Dimplex’s smart thermostat with non-Dimplex baseboard heaters?
Not confirmed as a universal retrofit. The connected system pairs with Dimplex’s own LPC and PC Linear baseboard hardware. Confirm compatibility before buying if you have other brands’ heaters.

Is Dimplex better than Sinopé for Quebec homes?
Not on demand response. Sinopé integrates with Hydro-Québec’s Hilo program; we found no confirmed equivalent for Dimplex. If that’s a priority, Sinopé is the more established choice.
