Great!  This means I have next years christmas present sorted ;-)

If I were to mount the weather station on our aerial pole (currently
highest
point, sticks about 1 meter out above roof top), does it need
unplugging
whenever there are lightning storms?  Or is it reasonable safe to
leave it
all running (just like the television really, have never unplugged
anything
electrical just because it is storming outside) ?

Q.
