For me it is quite recent...Controlling USB on Raspberry Pi

A Raspberry Pi that reads the time from the network, sunrise and sunset from a public API and opens and closes my blind uncle's curtains at the right times which can be set remotely from my mobile (or any other browser).

There is still the small issue of getting it to work with Alexa. This is the stumbling block to that -> Alexa 'retrievable' (not all strictly Perl)
