How to WiFi enabled?

how to enable to search for WiFi devices? I have a Light Projector, I want to try to see if it is possible to find it and add it to Homey Pro. I couldn’t find it anywhere in the settings. I use Smart Life app and Smart Star projector.
Used Lan cable

You will need an app that supports it as there is no generic WiFi device support.
You could try the Tuya app to see if that works.
