I have my "flight-hobbs" connected to a pressure switch, hooked up to
the secondary pitot tube (which also feeds the SmartASS talking airspeed
indicator). The pressure switch is set in such a way that it closes a
switch when the speed reaches 42 knots.
I guess this is close enough to really register flight hours (with in
mind the option to use the Europa as a motor-glider, so flight hours
might differ substantially from engine hours).

For the mandatory registration, you are allowed to use flight hours. For
all engine run-ups in your backyard, you don't need to register
anything. Although I unofficially keep an eye on the actal engine hours,
and just perform some maintenance accordingly, earlier than officially
required with regard to the flight hours.
