Hostname configurable #2

Hello, is there any way to set hostname instead of IP address? My 1080 unit change IP often after a power outage, When it change I have to set on homebridge and restart it. My sony unit register on network as Chromecast.local (and is not configurable as fa as I seen) so, perhaps a new parameter to setup this hostname or perhaps a boolean option to try to resolve default Chromecast.local hostname and not set ipaddress manually in homebridge config.

Have you tried to use Chromecast.local as ip? I think looking up the name server is out of control of homebridge and is handled by your network...

plugin crash when I set hostname (chromecast.local) instead IP. (192.168.0.237)

Ive searched about getaddrinfo ENOTFOUND error message and made additional test and I found that plugin have to be using some function that uses DNS to get address info. It does not try to resolve name locally, so it will never resolve a local name. Also Ive set a internet available hostname (www.clarin.com) in config.json and it works,

{
        "name": "Amplificador",
        "ip": "www.clarin.com",

This means that plugins resolves hostname, and of course cannot connect to it, but it resolves fine. see log message...

So, I think plugin shuld resolve address using local mDNS, due all devices are local. There is not need to resolve internet names due Sony devices will allways locally. There are others plugins that has options to discover devices.. like Broadlink-RM perhaps the same function could be implemented here.
