If there is no voltage, there is no power in the mains and ergo - we are in
the middle of a power outage, so take action. Know of something along these
(idea is to detect power failures, while powered by a "dumb" UPS unit - one

Good idea. You could use one of those AC Mains to USB
adapter/charger; which I think gives out 5V on the USB power line. A
USB cable into the computer USB port should be a good starting.
