Matter Protocol

Matter over Wi-Fi

The Meross Thermostat Central (US/CA) from Meross connects to your smart home over Wi-Fi. It joins your existing network directly, without a Thread Border Router or extra hub, and your Matter controller reaches it through your home router.

Wi-Fi Band

Most Matter Wi-Fi devices only connect on 2.4 GHz. If your router combines 2.4 and 5 GHz under one SSID, split them to avoid issues.

Same Network

Your phone, your controller and the device must be on the same network. Guest networks and separate VLANs can block Matter.

Power Use

Wi-Fi uses more power than Thread, so most Matter over Wi-Fi devices run on mains power instead of batteries.

Every Matter device needs a Matter controller, like a smart hub, display or speaker. See all Matter hubs →

The Meross Thermostat Central (US/CA) is certified on Matter 1.2, released in October 2023. It added nine device types: refrigerators, air conditioners, dishwashers, washing machines, robot vacuums, smoke and CO alarms, air quality sensors, air purifiers and fans.

Frequently Asked Questions

Does the Meross Thermostat Central (US/CA) need a smart hub?

Yes, but only a Matter controller from your platform, not a separate bridge. The Meross Thermostat Central (US/CA) connects straight to your home network. The controller can be an Apple home hub, a Google Nest speaker, an Amazon Echo or Home Assistant.

Does the Meross Thermostat Central (US/CA) work without internet?

Yes. Matter runs on your local network, so the Meross Thermostat Central (US/CA) keeps working when your internet goes down. Remote access, voice assistants and some Meross cloud features may still need a working connection.

Does the Meross Thermostat Central (US/CA) work with Apple Home, Google Home, Alexa and Home Assistant?

Yes. The Meross Thermostat Central (US/CA) is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Thermostat devices. Support for newer device types can differ per platform.

Do I need the Meross app to use the Meross Thermostat Central (US/CA)?

No. Any Matter hub can set up and control the Meross Thermostat Central (US/CA) without the Meross app. Some advanced features may not be part of Matter yet, so settings like firmware updates or special modes can still require the Meross app.

How do I set up the Meross Thermostat Central (US/CA)?

Open your smart home app, choose to add a device and scan the Matter QR code on the Meross Thermostat Central (US/CA) or its packaging. You can also type in the 11-digit Matter code instead. The app guides you through the rest. Keep the code safe, you need it again after a reset.
