I don't have many, I find home assistant is a tool in search of a need.
- Run the robot vacuum when I leave the house.
- When I arrive home or open the garage door after sunset, turns on the rear porch lights and then turns it off after 15 minutes. (I have a detached garage.)
- Turn on select outdoor lights at sunset.
- Turns off all outdoor lights at sunrise, so if I forget to turn off the lights around my deck they eventually do get turned off.
- I have a button near where I sit in the living room that controls all four lights in the living room.
- I have a button on my dashboard that just turns off all the lights in my house.
- I have a button near my bar that turns on multiple lights and a neon sign. I was intending to add effects and scenes around the bar too so I could press another button and have a show go off.
