Shelly Pro Dimmer 2PM

The Shelly Pro Dimmer 2PM 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 →

Does the Shelly Pro Dimmer 2PM work with Apple Home, Google Home, Alexa and Home Assistant?

Yes. The Shelly Pro Dimmer 2PM is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Dimmer Module, Energy Monitor devices. Support for newer device types can differ per platform.

Do I need the Shelly app to use the Shelly Pro Dimmer 2PM?
