Shelly PRO 3EM 120A v2
Matter Protocol
The Shelly PRO 3EM 120A v2 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 1.0
The Shelly PRO 3EM 120A v2 is certified on Matter 1.0, the first release from October 2022. It covers the core smart home devices: lights, plugs, switches, locks, thermostats, blinds, sensors, TVs and bridges, all running over Wi-Fi, Thread or Ethernet.
Frequently Asked Questions
Does the Shelly PRO 3EM 120A v2 need a smart hub?
Yes, but only a Matter controller from your platform, not a separate bridge. The Shelly PRO 3EM 120A v2 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 PRO 3EM 120A v2 work without internet?
Yes. Matter runs on your local network, so the Shelly PRO 3EM 120A v2 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 PRO 3EM 120A v2 work with Apple Home, Google Home, Alexa and Home Assistant?
Yes. The Shelly PRO 3EM 120A v2 is Matter certified, so it works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, as long as the platform supports Energy Monitor devices. Support for newer device types can differ per platform.
Do I need the Shelly app to use the Shelly PRO 3EM 120A v2?
No. Any Matter hub can set up and control the Shelly PRO 3EM 120A v2 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 PRO 3EM 120A v2?
Open your smart home app, choose to add a device and scan the Matter QR code on the Shelly PRO 3EM 120A v2 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.
