somtimes i had false positive

[volkerrichert]

sometimes i got {"mac":null,"host":null,"version":null,"address":"192.168.6.1","family":"IPv4"} form the discovery service which causes an connect error because this is my gateway. I dig into it and found the following answers inside discovery:

[
{"name":"_esphomelib._tcp.local","type":"PTR","ttl":4500,"class":"IN","flush":false,"data":"buero-schreibtisch._esphomelib._tcp.local"},{"name":"buero-schreibtisch.local","type":"A","ttl":120,"class":"IN","flush":true,"data":"192.168.120.75"},
{"name":"buero-schreibtisch._esphomelib._tcp.local","type":"TXT","ttl":4500,"class":"IN","flush":true,"data":[{"type":"Buffer","data":[98,111,97,114,100,61,101,115,112,48,49,95,49,109]},{"type":"Buffer","data":[112,108,97,116,102,111,114,109,61,69,83,80,56,50,54,54]},{"type":"Buffer","data":[109,97,99,61,56,52,102,51,101,98,51,102,54,54,100,97]},{"type":"Buffer","data":[118,101,114,115,105,111,110,61,50,48,50,49,46,49,50,46,49]}]},{"name":"buero-schreibtisch._esphomelib._tcp.local","type":"SRV","ttl":4500,"class":"IN","flush":true,"data":{"priority":0,"weight":0,"port":6053,"target":"buero-schreibtisch.local"}}]

This will point to an array of Buffer :[{"type":"Buffer","data":... and the regex will match. Could you please readd that
if (!match) return null;?

I'm runnig multicast-relay.py to broadcast mDNS, etc between my VLANs
