This is probably trivial for most, the issue here is I cant really run wires room to room (needs to be somewhat temporary solution) and I have multiple doors that need covering (and little experience with EPICS and hardware engineering)

I was hoping to use this value to trigger lights on or off. Unfortunately I can't modify anything with the x-ray controller, so I figure there has to be some sort of USB light on the market that runs on serial commands? Or maybe such a specific thing does not exist and requires a micro-controller and some work to make.

I was thinking of maybe trying to get the "Belkin WeMo Home Automation Switch" to work with EPICS, it is basically a power plug that connects to WiFi. But it is probably easier to find some USB LEDs and run cables.
