Errors with Waveman-Switch device

I face some issues with devices, that are not correctly recognized with OMG . I have a 433 Mhz based remote control, that is recognized by rtl_433 (native with a different SDR stick) as a Waveman-Switch device. This appears with the test version 775e81 and with the new version 1.6.0.
When I press some buttons with different channels selected, they are sometimes discovered by the OMG HA autodiscovery correctly and other times discovered als a Akhan-100F14 when I press a ON switch. Pressing the OFF switch, the device is discovered as a Smoke-GS558 device, but from time to time a config topic appears correctly for a Waveman-Switch.
See some samples below:
