This VD is a interface to the ping_shelly.lua which can also be found here. The IP-address needs to be configured as shown in the image. The port value ("109") is used/misused to set the number of the lua script in your HC2  ("_lua"). As example here the code for the "on" button: local _self=fibaro:getSelfId() local _addr=fibaro:getValue(_self,"IPAddress") local _lua=fibaro:getValue(_self,\"TCPPort\") fibaro:startScene(_lua,{_addr,"on"}) fibaro:sleep(1000) fibaro:startScene(_lua,{_addr}
