Newbie Question: Can I control a plug-in module with a switch that isn't wired to the outlet?

Sure, lots of choices for this. :sunglasses: Pretty much any smartthings – controlled device can be used as a trigger for any other smartthings – controlled device. There are several battery-operated buttons and switches that people put on walls. Or if you want to wire a regular networked switch in you can do that too. The trigger device will talk to the smartthings hub and the smartthings hub will talk to the pocket socket and everything will work fine.

The Cooper 9500 is a battery operated wall switch which looks exactly like a regular wall switch, so some people like that look. But again lots of choices.
