Direct Matter without a Shelly hub
Shelly 3EM-63 Gen3 is listed by CSA as a Matter over Wi-Fi device. That makes the Matter path direct: it joins a Matter controller over Wi-Fi and does not need a Thread border router or a Shelly bridge for the Matter endpoint.
The image and availability trail is weaker than for older Shelly shop listings. The Matter claim on this page comes from the CSA certification entry, so check Shelly regional availability before planning a multi-device install.
Setup path
For a meter, start with the electrical work. DIN-rail meters, CT clamps, and circuit monitoring should be planned around the panel, conductor size, and local code before the smart-home pairing matters.
Use Shelly's app or web interface for Wi-Fi onboarding, firmware, device settings, calibration, and any device detail that your Matter ecosystem does not expose cleanly.
What to verify
Matter should cover the common endpoint, but the valuable details can vary. For Shelly meters, plugs, and PM relays, verify wattage, energy totals, and reporting frequency. For flood and motor-control devices, test the exact alert or movement behavior before building routines around it.
Should you buy it?
Buy 3EM-63 Gen3 when the physical format fits the job and you want a direct Wi-Fi Matter path. Skip it if you need every Shelly app feature to appear identically in Apple Home, Google Home, Alexa, SmartThings, and Home Assistant.
Best for
- Homes or panels where circuit-level energy context matters
- Shelly users who want Matter visibility as well as Shelly tools
- Installations with reliable Wi-Fi near the meter
Skip if
- You need guaranteed energy charts inside every Matter app
- You cannot safely install or commission panel equipment
- A simple plug-level meter would answer the question
