I am new to the ISY world. I am trying to turn a light on at a given time and then turn it off again 2 hours latter. Here is my coding: If From Sunset + 45 minutes For 2 hours Then set 'Family room lights' 55% set 'Kitchen lights' 55% Else no actions Then lights come on, but have to be manualy turned off. What am I doing wrong?
