Meross Matter 24V WiFi Thermostat for Heating and Cooling

Meet the Meross Matter 24V WiFi Thermostat for Heating and Cooling — a precision-driven, energy-smart upgrade that puts total climate control in your hands. Built for 24V systems and powered through your existing wiring, it combines Matter connectivity with deep HVAC compatibility to deliver comfort you can feel and energy savings you can quantify.

Designed for real homes and real lives, this thermostat offers:

• Wide system compatibility — works with 95% of heating and cooling setups, including single or multi-stage furnaces, boilers, air conditioners, heat pumps (with or without AUX), and fan coil units. Not compatible with electric baseboard heaters. Before you buy, scan the QR code to check compatibility.
• Power and wiring clarity — requires a C wire to power up. If your current wiring lacks a C wire, a C Wire Adapter may be needed to ensure reliable operation.
• Matter-enabled for seamless smart home integration — connects via Wi‑Fi and works with Apple Home, Siri, Amazon Alexa, Google Assistant, and SmartThings, delivering hands-free control across ecosystems.
• Smart scheduling that respects your routine — configure 7x24-hour schedules so the right temperature is ready when you are, and energy is conserved when you’re away.
• Energy visibility and savings — track heating and cooling usage in the Meross app and optimize settings to trim bills. Real-world users can save up to 30% per year compared with traditional non-smart thermostats.
• Room-by-room potential with sensors — pair with Meross Smart Sensors (MS130 or MS100F) via a Meross Smart Hub to balance temperature across rooms or zones for consistent comfort.
• DIY installation in under 30 minutes — a straightforward setup wizard in the Meross app guides you from wiring to scheduling with confidence.
• Precise, user-friendly control — setpoint range from 5–35°C (41–95°F) with a precise ±0.5°C (±1°F) accuracy. The compact 3.6 x 0.9 x 3.6 in glass-panel design fits any space, while power draw remains under 1 Watt in standby.
