Also, for those who would like to set up really complicated rules, or rules with overrides like “if A, then B unless C is true” WebCore is a very sophisticated rules engine for SmartThings. It will let you do all that tricky stuff like have a motion sensor turn on a light unless you already turned the light on with the wall switch, and pretty much anything else you can think of. You may need help from experts in the community to get the rule set up just right, but there are many people who will be glad to help.
