I would probably add a mode since I like to do that and I like to use the built in smart apps first. For instance I have a “Company over” mode, which most of my voice notifications don’t run and the alarm doesn’t arm automatically etc.
so then if the switch is physically turned off, then change the mode to “watching tv”
here’s how to add modes, only takes a min or so: FAQ: How to Add a New Location Mode, or Manually Change from One Location Mode to Another (Classic App)
