Why We Love It
The Smart Thermostat That
Works with Everything
Nest costs $250. Ecobee costs $190. The Meross MTS200 gives you every platform they support — including Apple HomeKit — for a fraction of the price. Here's why it's our top pick.
Apple HomeKit Support
One of the very few affordable thermostats with full Apple HomeKit integration. Control it from the Home app, with Siri, or in automations — no workarounds needed.
Smart Schedules
Program different temperatures for morning, day, evening and night — automatically. Come home to a warm house without heating it all day. That's where the 23% savings comes from.
Away & Vacation Mode
One tap puts the thermostat into energy-saving mode when you leave. Geofencing lets it do this automatically based on your phone's location.
Energy Reports
Monthly energy usage reports in the app show exactly how much you're heating and cooling — and what it costs. Most thermostats charge extra for this. Meross includes it free.
DIY Install
Clear wiring guide with colour-coded terminals. Most people install it in 30 minutes with just a screwdriver. Compatible with single-stage heating and cooling systems.
Clear Touchscreen Display
Large, easy-to-read touchscreen display shows current temperature, set point, and mode. Works great as a traditional thermostat even without your phone.

Our Verdict: Best Smart Thermostat for HomeKit Users
If you're in the Apple ecosystem, the Meross MTS200 is the obvious choice. It's one of the only affordable thermostats with native HomeKit support — and it also works with Alexa, Google Home, and SmartThings, making it future-proof regardless of which ecosystem you're in. It won't learn your schedule like Nest, but at this price, the savings on energy bills alone make it a no-brainer upgrade. We've tested it for 6 months and the connection has been completely reliable.
