ssdp conflict with HDHomeRun DVR device #21

Closed funkyvisions closed 7 years ago

funkyvisions commented 7 years ago

Any ideas how to not conflict with a device already using ssdp 1900?

sudo lsof -i :1900 hdhomerun 110 _HDHomeRun 13u IPv4 0xcc0db234ab963427 0t0 UDP *:ssdp

If I disable that service then I can get homebridge to run. However, Alexa isn't discovering it. I'm trying to use this as a bridge from Alexa to my HomeKit enabled Insteon Hub (which then controls it's own protocol devices).

When I open the socket, I'm opening it with the 'reuse' flag.

udpServer = dgram.createSocket({type: 'udp4', reuseAddr: true});

I'm wondering if your hdhomerun is not opening the socket re-usable? I also had problems with Kodi using the same socket, and had to set this up to allow it to be opened as shared. And the problem with Kodi went away.

Sorry, was out of town. Just getting back to this. I'll check on the hdhomerun. But even if I removed the homerun I still couldn't get it to work. Shouldn't the device have been discoverable at that point?

Correct, it should have been discoverable. If you start in DEBUG mode there is logging around the setup of port 1900 and the discovery process. I have seen some issues with machines that have multiple network interfaces, but besides that it has worked very well for people.
