I suggest blocking the outlet on your firewall as the normal app for these outlets is communicating via servers in china ^^
Nevertheless this plugin uses UDP to directly switch the outlet.
If there are more users of this plugin I might implement auto discovery but for now I will not develop this further as it is working fine for the outlet I have and it looks like Amazon is not selling them anymore. ( I guess because it is lacking protective ground which I guess is required in europe)
