No reply?  This time period is too short for my needs 

Hi Leif, 

Sorry for having missed this one. The DWD ICON forecast is for 48hrs only, but that is from the moment of model start. Their modeling takes about 3 hours, then then data is pushed to our server (55Gb) after which our server is also processing for 2-3 hours. So all in all the advanced weather forecast visible in EV4 is for roughly 36 hours in general. 

Depending on the hour of the day (the DWD data is refreshed 4 times per day, aka every 6 hours) data for the day after tomorrow will be visible. At the moment EV4 has Advanced Weather Data up to midnight tomorrow because it is based on the DWD run of 00:00 last night. The next DWD run is at 06:00 which I expect to become visible about 7 hours later, so that would be 1300UTC today, and that should have data for the first hours for the day after tomorrow. I will keep an eye out on when this data should be available and report back
