Patrick,

I don't see anything necessarily unusual with your rain. WeeWX records 
rainfall on a per interval basis not a cumulative basis. So if during a 
loop period there is one tip of your rain gauge that will record 
(approximately) 0.2mm of rain in the loop packet for that period. If there 
is no further rain (or tips of your rain gauge) then the next loop packet 
will be 0.0. Also, it could be raining steadily but you might see a loop 
packet with rainfall but the next one or two (or more) may not. How often 
you see rain in a loop packet is dependent on how heavy the rain is, how 
big your rain gauge bucket is and how often you sample the rain gauge.

The best way to test your gauge and the driver is to manually tip your rain 
gauge while weeWX is running. As long as you take note of how many tips you 
do you should be able to tell if the correct number of tips (and therefore 
'rain') comes through to weeWX.
