# Shelly 1 Mini Gen3

Shelly 1 Mini Gen3 is a direct Matter-over-Wi-Fi relay switch for Shelly-heavy homes. The safer expectation is Matter for the shared endpoint and Shelly for firmware, diagnostics, and any detailed device settings.

## Ecosystem Support

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

## Best For

- Retrofit relay jobs behind a switch or outlet
- Shelly users who want direct Matter sharing
- Loads that only need reliable on/off control

## Skip If

- The wiring or load requirements are uncertain
- You need a finished decorative wall control
- You need dimming or power monitoring

## Setup Notes

- Confirm wiring, load type, neutral requirements, and enclosure space before buying.
- Install and test in Shelly before Matter pairing.
- Keep Shelly available for firmware and power or relay settings.

## Known Limitations

- Matter may expose relay control more consistently than power or diagnostic detail.
- Shelly app or web UI may still be needed for firmware, setup, diagnostics, and advanced behavior.
- Local Wi-Fi reliability still determines the normal Matter connection path.

## Pros

- Direct Matter-over-Wi-Fi relay control
- No Thread border router or Shelly hub required
- Compact retrofit module family
- Shelly app and web UI remain available for firmware and settings

## Cons

- Installation depends on wiring, enclosure space, and load type
- It is not a finished wall control by itself
- Shelly-specific settings may stay outside Matter

## Direct Matter without a Shelly hub

Shelly 1 Mini 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 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 1 Mini 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.
