These types of things are my favorite use cases. I set up a little test with a beacon inside my bedroom and now it automatically turns on the lights for me when I walk in (if I'm wearing my Apple Watch) and then turns them off when I leave. It's not perfect but it's very convenient.
I also have a few automations that are set up for when I leave the house to make sure music turns off and my thermostat is set to "Away" mode.
Yea, I have during the winter months a "when arriving home after sundown turn the lamp on" automation as well. During summer months I turn that one off.
I've generally really enjoyed basic smart home stuff. I have a handful of smart wall switches that work well, and for the lamp a wall-wart that I use. One of these days I'll just retrofit some actual lighting in the living room and can skip the lamp situation but until then... this is a nice workaround.
