Meteobridge with Davis Envoy - Rain difference

[assenzuid]

Hi,

I'm using Meteobridge together with a Davis Envoy Weather, but i notice some difference in the rain totals when I compare it to the Davis VP2 Console.
Meteobridge + Davis Envoy gives an higher rainfall (both for rain hour as last 24 hours).

Timesettings/ date are set on both (Envoy & Console) the same.
Both devices receive the same data from the ISS.

The rain multiplier settings in Meteobridge are default set on 1.0 and it's not possible to set it lower (example 0 or 0.0).

Thanks,
Weather station Assen south-west.
