Raspberry Pi, and an Instromet logger - USB/ serial adaptor

Topics about the Beta trials up to Build 3043, the last build by Cumulus's founder Steve Loft. It was by this time way out of Beta but Steve wanted to keep it that way until he made a decision on his and Cumulus's future.

Steve as it has rained today I have checked the Last Rainfall and it is indeed now working in MXversion 3041.

The only parameter that seems to be questionable is the Rainfall Rate which always displays 0.0mm/hr.

Does this need a similar modification due to the Instromet way of rainfall measurement?

many thanks

For stations that don't supply a rain rate, Cumulus has to calculate it - it uses a very simple calculation using the amount of rainfall in the previous five minutes. I've forgotten to set the flag that indicates that it needs to do this for Instromet stations - I'll fix it in the next build.
