Nope, I think I looked at it when I was in my flat with the bathroom internet lightswitch but never bothered installing it.

It's not annoying enough to spend money on. Just wondering if I could do it with the gear I've got lying around.

Might give it a whirl and see what options it gives.

Doesn't seem to work with my router (mine is on firmware 7.something, the custom firmware is 6.something)
