I admit I didn't search this specific forum directly, tho I believe I've come thru here (and a number of others) via searches :(( So, apologies if this has been handled....and I just haven't found it yet.
Simply, RPI 3, OSMC, TVH and HDHomeRun Connect (dual-tuner).
I can log into TVH config page and set up a network (ATSC) which appears to setup 13 muxes (shows 13 ch/frequencies for SF Bay area). However, nothing shows for TV adapters. I used the hdhomerun_config discover util and returns an 8 char (7 digs, 1 letter) ID number and a valid IP addr which fits into my home network, so the tuner seems to be active and accessible.
I installed (what I believe to be) TVH from Video/add-ons. I also did a separate install (found info in one of the forums, which may possibly have messed things up further). At this point, I'm not sure if I have done serious damage (software/logic-wise) so I could really use some help/guidance/a few head-slapping "D'ohs", maybe. However, fairly frustrated at this point in my progress, tho :(
Not a noob (not so much, anyway).....
Thanks in advance....
