I am not personally interested in integrating those but here are a few ideas I came up with:
- To monitor screen time. If a child is only supposed to watch for X amount of time this can help monitor it and, if needed, disable it
- Changing volume and/or automatically pausing when someone comes to the front door (or a motion sensor detects someone coming)
- Integration with OTHER aspects of the home that might cause excessive noise (ex: do not run the dishwasher while someone is watching TV)
- @marktheknife ninjaed one about lighting
- Start/stop on a schedule or timer for vacation purposes so the house is lived in.
