Turn off switch after being on for a period of time?

[JDRoberts]

If you want to be able to sometimes have the light turn off on a timer and other times not, you can create a virtual timer. See the how to article in the community – created wiki. (This article will also show you how the power allowance feature works.).

FAQ: What is WebCoRE? (And what was CoRE?)

CoRE (now WebCore) is a very powerful community – created rules engine for SmartThings. It allows you to set up stacked conditionals like “If A then B but only while C and not if D.” Setting it up can be quite complex, but there are many community members who will be glad to help you. For example, here is a piston that one member created to notify him if the dog had already been fed twice that day and he picked up the dog bowl for a third time. He needed this because he has a large family and people didn’t always remember whose turn it was to feed the dog.

This allows for flexibility and an architecture that requires more memory than is av…
