Openhab + Raspberry Pi + Yeelight

I installed Openhab 2.4.0 using dockers in a Raspberry pi 3 device, the thing is I can’t see my Yeelight device on the Paper UI.

Openhab is running on eth0.20 at 192.168.20.10

The Yeelight device (192.168.20.95) is connected to a wlan broadcasted by the raspberry pi 3

but still, under Inbox > Yeelight Binding > Search, the device is not found. I tried manual binding but I need to add a Device ID which I dont know where to find.
