Also, it is how you would want it to work surely?

Most people just want to sense standby to turn all the other stuff off and
still be able to use the remote to turn it back on again. If you can
actually be bothered to stand up, walk across and flick a real switch,
then
you might as well hit the one on the socket instead of the TV. No need for
electronic assistance.

I agree, what most people would want, however the OP was trying to prevent a
similar case as his friend who had a fire caused by a TV left on standby.
