I have actual obscure RGB corner floor lamps with BLE in my office. I had Claude find the BLE protocol and use my Office 365 calendar feed to change their color to red when I'm in a scheduled meeting (event), and back to warm white when the meeting is over, so co-workers know I'm busy without doing "are you busy" sign language through my window. The script is polled every 60 seconds. Tinkering with stuff like this is a lot of fun.
