As for the other topic, all of my TVs power down the USB when the TV
is off. That is actually pretty dandy because you can hook an SSR up
to the 5v and power anything else you have hooked up when the TV comes
on. On one TV it is the PC and amp. The other (smart) TV it powers a
disk drive, sound bar and a back light

Is there any particular type of SSR that you like?

Crydom is a pretty good brand. IBM used a bunch of them in 3890 check
sorters. These days they show up on Ebay a lot in the $4 range. It
will fit in the bottom of a "handy box" then you put a line cord in, a
USB connector to the LV side and top it off with a duplex receptacle
and cover. It is an easy way to control 120v with a low voltage input.
Typically a 5v input is around 5ma, well within the capability of a
USB port. If you put a wall wart in there in place of the USB
connector, you can easily split your Xmas lights across a couple of
circuits if you are going nuts with the lights and still control them
with one switch.
