Meross’s smart thermostat is crafted to streamline everyday comfort, blending intelligent scheduling and Matter-based local connectivity into one approachable package. Compatible with 95 percent of heating and cooling setups—including heat pumps, conventional systems, and more—it confidently manages temperature without supporting electric baseboard heaters. Set detailed weekly schedules, and trust them to run smoothly, even if Wi-Fi drops out.
Built-in Matter support ensures local, secure communication with your favorite platforms—Apple Home, Amazon Alexa, Google Home, or SmartThings—offering a responsive, private experience. The Meross app further refines control by tracking your heating and cooling habits, helping you trim energy expenses by as much as 30 percent per year. Extra features like remote access, quick installation, and child lock add thoughtful convenience for a home that feels both smart and approachable.
