Hello toby,
I have such a device and like werk said it is ment to close a roof or a sun awning when it starts raining. In principle those sensors work properly.
The upper graph shows the counts of an FO tipping bucket, the graph below the relay state of the rain sensor. So it has not much reaction time, but depending of the type of rainfall. Since the reading is from this summer this was probably a rain shower starting very fast.
But according to the manual, if you disable the integrated heating you can also detect fog with this device.

If you want to know some specific details I also can so some tests with it to check under which circumstances it detects rain.
