I downloaded the "k" release last night, purged the contents of the "data" and "logfiles" directory, manually loaded in the entire memory from the base unit via the traditional way (Easyweather), then turned on the direct mode.
No blips, constant readings, and no rain weirdness.
In the "last 24 hour" graph, the gap in the graph from about 20:00 to 23:00 was loading in the manual data file (it takes a while to suck in 4079 records!) and then forgetting to turn on direct mode for a while.
Looks like it's right now. Rain graph seems congruent with when it was raining and the kind of intensity of rain. Looks like this version is a winner.

I'm keen to "completely flush" all records from WeatherDisplay completely (monthly totals, yearly totals - everything) and start clean. Anyone know how to do this "properly"?
