LYASI Wifi Smart switch

Hi everyone,

I am quite new to openhab and very happy that i put the first widgets on my dashboard like philips hue and so on.
the way i do this is - i guess it is the beginners way:) - i am looking in the paper ui for addons and then add everything i need.bindings, things, items and so on.

but now there is a problem: what to d if my switch is not listed in the addons tab? in this case it is about this switch: https://www.amazon.de/gp/product/B075ZT7VLB/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

so maybe some can help me to turn on my christmas light via dashoard using this smart device…
