Is your feature request related to a problem?

I installed OpenMQTTGateway on a LilyGO 433 board. The Cardin-S466 sensor is detected incorrectly as a Smoke-GS558 detector.
When tested with an RTL-SDR, the sensor is recognized correctly as Cardin-S466.

Describe the solution you'd like

Add proper support for the Cardin-S466 sensor in OpenMQTTGateway so it is identified and decoded correctly.

Describe alternatives you've considered

  • Using an RTL-SDR works, but it requires a separate host device, which is not a practical solution for embedded deployments.

Additional context

If helpful, here is the RTL_433 output when the Cardin-S466 sensor is received from the board:
