Intention:

Currently, I live with my sister in a 3 story townhouse. During the late evening hours, I am usually upstairs in my office busy innovating the next generation of IOT products and do not venture downstairs again until morning. After a long day at work, my sister usually likes to relax and watch TV downstairs. During this time, she usually burns several candles that are scattered throughout the living room. In the event that she falls asleep, I want to ensure that candles are not left burning unattended all night.
