My parents recently got the DP-UB820 player at their summer home/cabin. They got it added in to their current C4 implementation by a somewhat local dealer, but they're in very rural Northern Wisconsin w/notoriously bad internet so any sort of support is a horrid remote experience or incredibly pricey to get the installer there (the C4 system was there when they bought it just a couple years ago).
Until recently the unit was working fine. My dad, who has who is quite knowledgeable about his C4 system, did mention the installer used either the UB900 or UB9000 driver to make the UB820 work w/IP control and the installer did also enable the Alexa/Google integration since that evidently helps (something confirmed by a c4forums post) on the UB820.
The problem is now they've been having some issues controlling over IP. Best we can tell IR still works, but as mentioned it was all meant to work via IP. Before they spend any money having the C4 dealer come out, pay for the trip, just to find out the unity is faulty from an IP control standpoint, we were hoping to test powering on and off the unit (and maybe a few other commands). We've already contacted the dealer with this request but he was, well let's just say, not wanting to help us or truly didn't know how to provide what we were asking for.
Presumably this IP control is all done via SOAP or REST commands (assuming SOAP given the little bit of googling I've done I've noticed C4 drivers are XML files). I'm not looking to change anything with the C4 config/install itself or get any free C4 work from anybody here, but am simply wondering if anyone or an installer could simply provide us a few commands C4 is sending to the UB820 for us to try out ourselves.
Any help with this to provide a couple of these commands would be more than so so greatly appreciated!! (Tom, my dad, agrees as well!)
