I installed both skills. So I can now say Alexa turn harmony volume up/down. What in cannot do is pause. Alexa doesn't recognize the command.
So I wanted to learn the pause button from the Mi box remote but the hub doesn't want to learn it. So I tried it on my harmony remote and same issue.
I'm stump why it is this difficult to have a code pause!
I think you need to add a Bluetooth keyboard to harmony and manage it that way
