I am sure I have done this in previous iterations of the Harmony software, but I can't find it in the current one. I have got an HDMI switch in my system that I want to leave on all the time. In the past it has autoswitched the input so I have not used Harmony to control it, but now I want to switch the input manually when I start an activity. If I add the switch to the activity, then the Harmony turns the switch on at the start of any activity and off at the end, which I don't want. One workaround I have considered is adding the 'change input' button on the HDMI switch as a button on another device so that I can leave the switch out of the activity altogether. The only problem here is finding the original remote for the switch, so I am looking for other options.
