@marliespeters Windy do not provide GRIB files. And I’m quite sure you already receive GRIB files via your Iridium Go (Probably based on GFS model). So what should be the advantage of receiving GRIB file from Windy? Getting the same maps as you see on Internet? That’s not possible, because the way how a GRIB file is displayed depends on your GRIB file viewer , not on the provider.
