All is working as I want, I was confused on a couple of points in the docs. In retrospect mostly my fault not comprehending what I was reading but others may fall into the same trap so the details remain below.
Update: I’ve figured out one is supposed to run either the Docker image or the console app, not both. Sorry if I missed that in the docs or perhaps it’s implied but it sure wasn’t obvious to me reading the install guide.
I’ve got the Docker image doing what it’s supposed to do, however in Roon Extensions I see 3 extensions all stating theres an update and only one of them discovers my single Harmony Hub. All 3 reports v2.10+243 and that v2.11+246 is available. All 3 updated fine and I can ignore the two that exist but don’t have a hub associated…
P.S. Is it possible to have just skip functionality of v1? I don’t use fastforward and would prefer both short and long press be skip (forward or back, respectively) but don’t see a function available to assign in Harmony button setup for the TCL.
Update: just found InputAV and InputUSB are what I want, thanks.
