Not the things that you depend on, but automations that are just for fun
On Christmas morning, when the motion sensor in the hallway next to the living room is triggered, it slowly turns on the Christmas tree, turns on the stereo, sets the stereo volume to 0, starts a Christmas music playlist, then slowly turns up the volume.
When my girlfriend is over and the freezer door is open, I play ice ice baby. It never fails to cause some eye rolls
When I turn the coffee maker on (or off), it’s light also gets turned on (or off). I couldn’t just used the same switched socket for both, but I had one free so here we are.
My Chromecast slowly stopped turning on the sound system and TV via CEC so instead of buying a new one, my family knows there’s a red button in the theater room. It cuts the power to the Chromecast via a smart switch and then power cycles the TV and sound system. Saved us $100 and the world some e-waste.
