Matter Protocol

The Shelly Switch 1L Gen4 from Shelly 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 1.3

The Shelly Switch 1L Gen4 is certified on Matter 1.3, released in May 2024. It added energy reporting for any device, plus EV chargers, water valves, leak and freeze sensors, ovens, cooktops, microwaves, extractor hoods and dryers. Scenes also became part of the standard.

Frequently Asked Questions

Does the Shelly Switch 1L Gen4 need a smart hub?

Yes, but only a Matter controller from your platform, not a separate bridge. The Shelly Switch 1L Gen4 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 Shelly Switch 1L Gen4 work without internet?

Yes. Matter runs on your local network, so the Shelly Switch 1L Gen4 keeps working when your internet goes down. Remote access, voice assistants and some Shelly cloud features may still need a working connection.

Does the Shelly Switch 1L Gen4 work with Apple Home, Google Home, Alexa and Home Assistant?

Yes. The Shelly Switch 1L Gen4 is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Switch Module devices. Support for newer device types can differ per platform.

Do I need the Shelly app to use the Shelly Switch 1L Gen4?

No. Any Matter hub can set up and control the Shelly Switch 1L Gen4 without the Shelly app. Some advanced features may not be part of Matter yet, so settings like firmware updates or special modes can still require the Shelly app.

How do I set up the Shelly Switch 1L Gen4?

Open your smart home app, choose to add a device and scan the Matter QR code on the Shelly Switch 1L Gen4 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.
