But it could be serious.

I've just downloaded the latest data from the weather station, and sat here
looking at the graphs. First thing that came to mind was "Wtf did that come
from?" At 6 o'clock yesterday morning, 0.6mm of rain was recorded, yet when
I came to water the plants this evening, the water butt was all but empty.
That water butt will fill easily with less than a millimetre of rain
(catches four roofs = 100+ sq m), so obviously no rain fell.

Since I keep a wildlife friendly garden, and assuming some pesky bird
(probably a pigeon) landed on the sensor and rattled it, how do you prevent
that sort of thing happening. I certainly can't blame the dog for this one.

Come on folks, one of you must some idea on this one.
