Direct Matter without a Shelly hub
Shelly 2PM 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.
Setup path
For a relay, start with wiring, load type, enclosure space, and local electrical code before the app setup.
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 2PM 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.
Best for
- Retrofit relay jobs behind a switch or outlet
- Shelly users who want direct Matter sharing
- Loads where power draw helps automation decisions
Skip if
- The wiring or load requirements are uncertain
- You need a finished decorative wall control
- Your ecosystem must expose full power history
