Matter Protocol

The Meross Smart Thermostat Valve from Meross uses Matter over Thread to connect to your smart home. Thread is a low-power mesh network built for devices like a Thermostat, TRV. Devices pass messages to each other, so the mesh gets stronger and reaches further with every router you add.

In a Thread network, the Meross Smart Thermostat Valve works as a End Device (MTD).

Border Router (TBR)

A Thread Border Router connects your Thread devices to your home network, so no extra hub is needed.

Router (FTD)

A Thread Router stays powered on and relays messages for other devices, extending the range of your network.

End Device (MTD)

A Thread End Device talks to nearby routers and does not relay messages, which saves power and battery life.

Every Thread router you add makes your mesh stronger and extends its range. See all Thread devices →

Matter Version

Matter version unknown

The Matter version of the Meross Smart Thermostat Valve is not known. We could not find it in the official CSA certification data for this device. It still works as a Matter device, but which features it supports depends on its certified version.

Frequently Asked Questions

Does the Meross Smart Thermostat Valve need a smart hub?

Yes. The Meross Smart Thermostat Valve needs a Thread Border Router to reach your home network, plus a Matter controller from your platform. Most devices handle both, like a HomePod mini, Google Nest Hub (2nd gen) or Amazon Echo (4th gen). See all border routers

Does the Meross Smart Thermostat Valve work without internet?

Yes. Matter runs on your local network, so the Meross Smart Thermostat Valve 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 Smart Thermostat Valve work with Apple Home, Google Home, Alexa and Home Assistant?

Yes. The Meross Smart Thermostat Valve 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, TRV devices. Support for newer device types can differ per platform.

Do I need the Meross app to use the Meross Smart Thermostat Valve?

No. Any Matter hub can set up and control the Meross Smart Thermostat Valve 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 Smart Thermostat Valve?

Open your smart home app, choose to add a device and scan the Matter QR code on the Meross Smart Thermostat Valve 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.
