Direct Matter without a Shelly hub
Shelly Plug S MTR 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.
Setup path
For a plug, the physical setup is simple: put it where 2.4 GHz Wi-Fi is reliable, update it in Shelly, then add it to the Matter app you actually use.
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 Plug S MTR 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
- Lamps and appliances where a Shelly plug format fits
- Shelly users who want direct Matter sharing
- Homes with reliable Wi-Fi at the outlet
Skip if
- The regional plug format is wrong for your outlet
- You require portable energy history in every ecosystem
- Your 2.4 GHz Wi-Fi is weak where the plug will sit
