Yeah! Weird device that I've never come across before. I kinda want to fit one in my DB just for the gimmick value.
It's basically a digital counter with nonvolatile memory, that detects high current pulses being shunted by a surge protector and gives a running score.
This could be used to monitor for when a new surge protection module was needed, but it is only designed to detect high current pulses, so won't show the accumulated smalltransient shunting that can be caused by highly inductive loads in the vicinity.
Quite novel though, with sensible design and a stunningly low standby current of just 0.1W.
Given that the input is electrically isolated (on this particular unit), I wonder if it could have other event counting uses with a simple low voltage input.

This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
