I have my lights set to turn on slightly before I am supposed to wake, turn off after I go to work, before I return from home, and after I go to bed. I’ve recently added mmwave sensors to turn them on and off based on my presence within a room. I can do all kinds of automations that I could do manually sure but if I don’t need to and can minimize the amount of excess energy waste then why wouldn’t I want a wirelessly controlled switch and or lights?
And yes most everyone can do this. Google Home Assistant and get lost in the rabbit hole.
