Thank you again, Larry. That should keep me busy for awhile!
I’m Back! I got fairly far along this trail, but am stumped once again. Here’s where I got:
The device is saved, as instructed. No power buttons selected, as instructed. I have no remote control - just the hub. How do I “setup a music related activity without the Roon Controller, and then re-run the activity adding in the Roon controller”? The only device I have in the Harmony app is the Roon Controller. Then, how do I get to the place where the Harmony buttons and the Roku commands are paired? (I have no physical remote control with actual buttons.)
