Matter Protocol

Matter over Wi-Fi

The Sonoff TX Gen2 Switch from Sonoff 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 →

Matter Version

Matter 1.4

The Sonoff TX Gen2 Switch is certified on Matter 1.4, released in November 2024. It added solar panels, batteries, heat pumps, water heaters and home routers with Thread built in. It also brought energy management, easier multi-platform setup and longer battery life for sensors.

Frequently Asked Questions

Does the Sonoff TX Gen2 Switch need a smart hub?

Yes, but only a Matter controller from your platform, not a separate bridge. The Sonoff TX Gen2 Switch 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 Sonoff TX Gen2 Switch work without internet?

Yes. Matter runs on your local network, so the Sonoff TX Gen2 Switch keeps working when your internet goes down. Remote access, voice assistants and some Sonoff cloud features may still need a working connection.

Does the Sonoff TX Gen2 Switch work with Apple Home, Google Home, Alexa and Home Assistant?

Yes. The Sonoff TX Gen2 Switch is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Wall Switch devices. Support for newer device types can differ per platform.

Do I need the Sonoff app to use the Sonoff TX Gen2 Switch?

No. Any Matter hub can set up and control the Sonoff TX Gen2 Switch without the Sonoff app. Some advanced features may not be part of Matter yet, so settings like firmware updates or special modes can still require the Sonoff app.

How do I set up the Sonoff TX Gen2 Switch?

Open your smart home app, choose to add a device and scan the Matter QR code on the Sonoff TX Gen2 Switch 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.
