Here is a wireless light socket control.  Control up to 150W bulb from up to 100 feet away. $23 at Home Depot.

You would need to replace the mechanical switch part with a relay device like the one I mentioned earlier.

Yes there are definitely 120V outlets to work with. I should have specified this in my original email.

Do the locations where you want to mount the lights have 120V power available.  Or will you need to run a wire for that at least?

Not really, it is an x-ray controller box that is under warranty so I can't open it. Maybe I shouldn't say interlock. it is basically a box with a key sticking out of it. It already has an led in it. The thing is EPICS knows the status of the key so I was hoping to use that..

Wondering: can you power a LED from whatever powers the interlock?
(Maybe 'power' isn't the right word here, 'control' would
probably be better)

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.

>> How is your interlock done?  Simple relays or with a PLC?  Our laser interlocks here at APS use inexpensive PLCs, and they directly operate the warning lights outside the enclosure.

>> Anyone have any suggestions for a simple way to control a light with EPICS? It does not need to be bright, even a small LED will do. Basically I'm trying to have indicators on several doorways to show the current status of the interlock on our x-ray source (which is already a PV).

>> In the ideal scenario it would be connected to wifi so that ethernet/usb cables do not need to be run everywhere. 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.
