Auto-discovery unkown smart device

Dear all,
i just installed new Chinese RGBW LED WiFi bulbs but i can use them only with Owner App and Alexa Skill.
I was not able to figure out and to configure them in Home Assistant.

Is there a method to scan the local network and discoverthe unknow devices to configure them manually?

I already wrote a post with all test already done.

Thnx in advance and best regards,
