Something like 20 years ago, I tried to grow a plumeria flower in my apartment. I had a broad-spectrum light, plenty of heat, and plenty of humidity. But getting the light turned on and off at the right times wasn’t easy (especially if I was at work all day!).

This seems like a really good use for home automation — our home automation system tracks the sunrise and sunset times for our zip code. It’s possible to essentially cron “stuff” off of these times — e.g. get the birds ten minutes before sunset. I could easily track sunrise and sunset in Honolulu then have my light turn on at sunrise (or first light) and off at sunset (or last light). Voila — “sunlight” that runs for the proper duration every day.
