# Shelly Pro 3EM 3CT63 Gen4

Shelly Pro 3EM 3CT63 Gen4 is a direct Matter-over-Wi-Fi energy meter for Shelly-heavy homes. The safer expectation is Matter for the shared endpoint and Shelly for firmware, diagnostics, and any detailed meter data.

## Ecosystem Support

- Apple Home: Limited
- Google Home: Limited
- Alexa: Limited
- SmartThings: Limited
- Home Assistant: Limited

## 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

## Setup Notes

- Plan the electrical installation before pairing.
- Use Shelly for firmware, meter settings, and any detailed power history.
- Pair through Matter only after the meter is installed and reporting correctly.

## Known Limitations

- Matter energy and meter entities are not displayed identically across platforms.
- Shelly app or web UI may still be needed for firmware, setup, diagnostics, and advanced behavior.
- The matching Shelly shop listing for this exact certified model was not available in the current product search; this page uses the CSA certification and nearest Shelly family imagery.

## Pros

- Direct Matter-over-Wi-Fi meter listing
- No Thread border router or Shelly hub required
- Useful for circuit or panel-level power visibility
- Shelly app and web UI can remain available for deeper settings

## Cons

- Meter data exposure varies by Matter ecosystem
- Panel or CT work may require an electrician
- The matching Shelly shop listing for this exact certified model was not available in the current product search; this page uses the CSA certification and nearest Shelly family imagery.

## Direct Matter without a Shelly hub

Shelly Pro 3EM 3CT63 Gen4 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 Pro 3EM 3CT63 Gen4 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.
