The most recent thing I setup in HomeAssistant + NodeRed was an automation for my front porch lights, which are connected to a Lutron Caseta switch. When my Ring doorbell detects motion at night, the lights will turn on at 31%, and stay lit for 20 minutes. However this automation won't run if the lights are already turned on at some level other than 31%. Any subsequent detected motion increases the duration so that they stay on for 20 minutes after the last detected motion.

I also use Alexa to fake lights being turned on throughout the house when I'm away for an extended period of time, so the house doesn't seem as empty. There's a HomeAssistant extension that will record normal behavior in your house, and replay it on demand, which I'm thinking about using to randomize the lights even better.
