The short version: The Netatmo Smart Thermostat is a battery-powered, E-Ink-display thermostat built for boiler-based (hydronic) heating, not the electric baseboard or forced-air furnace setups most Canadian homes use. If you’re one of the households with a gas or oil boiler feeding radiators, it’s a well-designed, subscription-free option with real HomeKit support. It is not a fit for baseboard heat — for that, look at Mysa, Sinopé, or Stelpro instead.

Who It’s For

Netatmo is a French company (now owned by Legrand) that designed this thermostat around European heating norms: a boiler heating water that circulates through radiators or in-floor loops. That setup shows up in older Quebec and Ontario housing stock, converted multi-unit buildings, and some heritage homes, but it’s a minority of Canadian heating systems overall — most homes here run forced-air furnaces or electric baseboard.

Confirm your heating type before ordering. Netatmo publishes a compatibility checker on its site. If you have electric baseboard heaters, this product will not control them; if you have a standard forced-air furnace, look elsewhere in our lineup.

It’s sold in Canada almost exclusively through Amazon.ca — it isn’t stocked at Best Buy, Home Depot, or Canadian Tire.

Design & Build

The design is the standout. Netatmo worked with French design firm Starck on a round, minimalist puck with an E-Ink display (similar to a Kindle screen) that runs on two AAA batteries rather than being hardwired to the wall. Tap the top or bottom to nudge the temperature until the next scheduled change. It reads more like a small piece of decor than a utility device.

Setup & Compatibility

Wiring: A relay module wires into the boiler; the thermostat itself is wireless and can sit anywhere in the home rather than being mounted near the boiler. Installation is manageable for a DIYer comfortable with basic low-voltage wiring — if you’re not, have an installer handle the relay connection.

OpenTherm: For boilers that support OpenTherm, Netatmo can do modulating (rather than simple on/off) control, giving finer temperature management than a basic relay setup.

No subscription: Scheduling and remote access work without any monthly fee.

App & Ecosystem

Netatmo supports Apple HomeKit, Amazon Alexa, Google Assistant, and IFTTT. HomeKit support in particular sets it apart from most of the Canadian smart thermostat market, which leans Alexa/Google-only.

Digging into independent user reports (Home Assistant’s GitHub issue tracker, Netatmo’s help center community, and other forum threads) turned up a consistent set of complaints worth flagging:
– Displayed temperature drifting from the actual room reading over time, which can keep the boiler running longer than needed
– The relay occasionally showing as disconnected, requiring a re-pair
– App behavior reportedly getting worse after some software updates, per user accounts
– Slow customer service turnaround reported by multiple users, including at least one account of a multi-month wait on a warranty issue

These aren’t universal experiences — many users report no issues — but they came up often enough across independent, unrelated sources to be worth noting rather than glossing over.

Standout Feature: Expandable Smart Valves

Netatmo also sells Smart Radiator Valves that pair with the thermostat for room-by-room control on radiator systems — useful if you have several radiators and want to run bedrooms cooler than living spaces without replacing the whole heating system.

The Recommendation

Buy the Netatmo Smart Thermostat if you have a boiler-based heating system, want native HomeKit support, and like the option to expand to per-radiator control later. Run your system through Netatmo’s compatibility checker first.

Skip it if you have electric baseboard or forced-air heat (it won’t work), or if the temperature-drift and connectivity complaints found in independent reports concern you.

Frequently Asked Questions

Does the Netatmo Smart Thermostat work with electric baseboard heaters?
