TVheadend + HDHomeRun on second NIC with static IP

[antamone]

Should it be possible to use an HDHomeRun Dual tuner connected directly to a network adapter on an OpenELEC system running the Tvheadend backend? According to the MythTV site this should be possible using a MythTV backend, but I'm using Tvheadend. So far I have been unsuccessful trying to get it to work.

I'm running the OpenELEC 64-bit Intel 2.99 RC3 release. I have enabled the HDHomeRun dvbhdhomerun add-on, and configured it with the HDHomeRun's Device ID.

I have enabled the Tvheadend backend and frontend add-ons. The computer is connected to the network via an Ethernet cable connected to the motherboard's onboard NIC. The HDHomeRun Dual tuner is connected to the computer via a TRENDnet TU2-ET100 10/100Mbps USB 2.0 network adapter (an adapter I saw mentioned by another poster in this forum).

I would assume OpenELEC is using the first network connection in the OpenELEC settings module for network access, and I configured that connection accordingly. I do have LAN and Internet access to and from the OpenELEC box, as I can connect to it over the LAN and OpenELEC is able to pull down add-ons. I set up the second network connection in the OpenELEC settings module as closely as possible to the MythTV guide for using an HDHomeRun tuner directly connected with a static IP.

Here's the thing. I have an existing HDHomeRun tuner on the LAN (which I don't want to use with this OpenELEC box). The Tvheadend backend seemed to see this tuner, until I disabled that tuner's Device ID in the dvbhdhomerun add-on config. I of course also added the Device ID of the HDHomeRun Dual tuner directly connected to the OpenELEC system to the appropriate section in the dvbhdhomerun add-on's config file, but the Tvheadend backend doesn't detect this tuner.

I'm not sure where to go at this point, and would appreciate any ideas anyone might have as to what I might try next.

Start with some log files

Code:

ifconfig -a | paste
paste /var/log/dvbhdhomerun.log
paste /var/log/messages

and then we will see how to proceed.

Btw: with latest addon 3.0.2 you don't need to manually edit config file anymore - everything can be set from hdhomerun addon settings.

Thanks ultraman! Here are the logs.

You forgot to post ifconfig log.
As you can see no hdhomerun devices was found.

Here is the output of ifconfig (didn't see it in your post until after I posted the first logs): http://pastebin.com/srmsW2Ud

Fix your subnet mask from 255.255.255.0 to 255.255.0.0. Maybe this would help.
After reboot check /var/log/dvbhdhomerun.log. If doesn't work try to increase Pre wait time in hdhomerun addon settings from 2 sec to 10 for example. Just for test.

Really? In mine (v3.0.2) I see General with "Pre wait time [sec]" and "Post wait time [sec]," and Tuner settings with "Enable modifying settings" and "Refresh... ." Is there supposed to be a way to add and configure tuner Device ID's in the add-on's interface?

[ultraman]

I though this "Refresh... ." would be self explanatory When you select it and confirm with pressing OK/ENTER on remote it will scan for devices and show them. But only if devices are visible.

Seems I have to change this to ""Refresh... [Press ENTER for action].

Could I do this just for eth1 in OpenELEC's settings.xml? LAN and Internet connectivity seems to be working okay on eth0, and I'd rather not make changes as I had issues earlier.

If I can add it to the settings.xml file, would the parameter be called NET2_NETMASK? That would seem to be logical, but I don't see any parameter that would seem related to netmask for either interface in the file right now so I just want to be sure.

Ohhh, I got it now, thanks. I did understand it was clickable/pressable, just not what exactly it was supposed to refresh. Maybe "Refresh tuners..." or "Refresh devices..." would make it clearer for dense heads like mine.
