I love walking into my kitchen and having the lights come on at an appropriate brightness based on time of day without having to interact with the switch. I love having my gawdy custom LED lights come on in the hallway when I open my bedroom door, and having them super low at night when it’s dark so I can still see without blasting my irises. I like having a heater that runs on one end of the room until the other end hits a certain temp, and more so only having it come on if the temp is below a specific threshold in the morning. I love having my porch lights turn on and off with sunset/sunrise, and having seasonal lighting schemes. I love knowing when my house is entered and exited when I’m away, knowing that I can control many things while out of the house like lights, or if I need to open the garage door for a friend to grab something, or give access to someone once without having to give them a key, or to have the TV room turning on before I head in there so I don’t have to bother with sitting through the power up cycle for everything. Mostly, I like being able to control lights without them having to be on the same circuit. My living room doesn’t have a light fixture with a switch, but I’ve got 4 lamps and two switched down lights (one at my front door and one over the fireplace) that are all controlled from a single wireless switch, button on my phone, or voice command. My bedroom is the same, I don’t have to turn out the lights and then get in bed in the dark. I get in bed and press the action button on my phone (which works conditionally based on time, location, and a couple other consistent factors) and the lights turn off while the fan turns on. It’s a lot of work for a bunch of minor conveniences, but more than anything I really enjoy the technology and seeing what other weird and stupid things I can do with it.
