I have a ton of east-facing windows on the back of my house. It’s a blessing or a curse depending on weather and time of day. I always dreamed about them running automatically, and eventually ordered a bunch of Z-wave controlled motorized shades. Then a Raspberry Pi running Home Assistant to control it all.

While I was waiting for those shades to arrive, I got a bunch of Kasa light switches so I didn’t have to sweep across the entire house to turn off all the lights every night. Turning the hallway light off after 9:45PM triggers the automation.

The rabbit hole only got bigger from there.
