Device Discovery Methods

[mski]

Which device discovery methods are available to find HDHomeRun on the network?

I’ve found:
o http://ipv4-api.hdhomerun.com/discover JSON external API
o mDNS
— hdhomerun.local
— hdhr-xxxxxxxx.local (where xxxxxxxx is the device id)
— xxxxxxxx.local where xxxxxxxx is the device id
o others?

The official method is hdhomerun_discover.[ch] in libhdhomerun.

You can also use UPnP to discover tuners, through not the DVR service.

Thanks for the pointer. Specifically, is the discovery method used the Simple Service Discovery Protocol (SSDP)?

Regarding (un)official methods, would you like me to avoid using the hosted API?

[nickk]

Best to avoid the hosted API. It is good for bring-up tests but won't work with all ISPs.

The web API is a reasonable option as a fallback, or as the unofficial Kodi addon does, a default-disabled configuration option for those who can't use SSDP or broadcast discovery for various reasons. As Nick mentioned, it doesn't work at all on ISPs that use carrier-grade NAT, which includes AT&T Mobility (LTE/fixed wireless) and Hughesnet satellite in the US, which make up a not insignificant portion of the userbase.
