Is there any documentation explaining how to interact with Harmony Hub on say Eisy through PG3? I'm seeing all my hubs etc and all looks configured correctly however how do I now actually use it? e.g. If a specific activity is run on a specific hub (which would be a condition), I want to run a program to dim the lights. Same in reverse, when I press the off button on the Harmony remote, I want lights to come back up. I can't intuitively see how this can be done.
