🌡️ Quick Picks
Why Matter Smart Thermostats?
Your thermostat controls the single biggest energy expense in your home — heating and cooling accounts for nearly 50% of a typical utility bill. A Matter-certified smart thermostat doesn't just save energy; it works with every major smart home platform simultaneously.
Before Matter, choosing a smart thermostat meant locking into one ecosystem. A Nest thermostat worked best with Google Home. An Ecobee paired with Alexa. Now with Matter, your thermostat integrates with Apple HomeKit, Amazon Alexa, Google Home, and Samsung SmartThings — all at once. Switch platforms without replacing hardware.

- HVAC compatibility — works with your specific heating/cooling system

Smart Thermostat Buying Guide
Check Your HVAC Compatibility First
Before buying any smart thermostat, check what type of heating/cooling system you have. Most smart thermostats work with standard 24V central HVAC systems (forced air, heat pump). If you have electric baseboard heaters, you need a high-voltage thermostat like the Meross MTS215. For boiler/hydronic systems, look at the Meross MTS215B or Eve Thermostat.
C-Wire: Do You Have One?
Most smart thermostats need a "C-wire" (common wire) for power. If your current thermostat only has 2 or 4 wires, you may need to run a C-wire or use an adapter. The Nest Thermostat (2020) can sometimes work without one using battery power, but performance is better with a C-wire.
Learning vs. Programmable
Learning thermostats (like the Nest 4th Gen) observe your patterns and auto-adjust. Programmable thermostats (like the Meross MTS300) follow a schedule you set manually. Learning thermostats are more convenient but cost more. Most users do fine with manual scheduling.
Thread vs. Wi-Fi for Thermostats
Unlike smart plugs and lights where Thread is clearly better, thermostats only communicate a few times per hour. Wi-Fi is perfectly fine for thermostats — the latency difference is imperceptible. Thread is a nice bonus (Eve Thermostat, Nest 4th Gen) but shouldn't be a deciding factor.
