Sonoff S20 with Tasmota discovered as light

Hi,
i have a Sonoff S20 smart plug, flashed with Tasmota. The Homeassistant MQTT discovery discovers this device as a light, however it should be discovered as a switch. I have no idea how i can change that, can anyone point me into the right direction?

Have you tried “setoption30 0” from the console?

Yes, that helped. Thanks for pointing it out.
