WiFi light switch support (Cheapish Ebay Purchase!)

Hey everyone, I was wondering if anyone in Europe has used the following light switches from ebay…

They are priced ok and look very nice! But I’m not sure of OpenHABs support for generic WiFi devices.

P.S I’m very new to HA so be easy on me!

UP !! It look cool and I’m looking for a wifi switch compatible with openhab

Or … Which wifi or bluetooth switch is compatible with openhab ?
