Hi, I am trying to set up activities for my harmony companion remote and harmony hub. Basically I would like an activity to switch on my Phillips TV, Sky DVR and change the input on the Marantz AV receiver to sat then switch the Marantz NR1504 AV receiver off so that the sound come from the TV not the AV receiver but at the moment I can only get the sound to come from the AV receiver as I cant add a step to turn the AV receiver off. I have tried not including the AV receiver in the activity but then the input stays on whatever other device was last used such as the PS4 or fire TV. Can anyone with some experience offer some help or suggest another way around it? Thank you.
