@sdetweil

I didn’t have to give a credit card, I don’t have one either, so it won’t work at all? Is the location option correct? Thanks for the effort and answering the questions

@Sam-0 I read your post but I can’t figure it out. Does the entire option not work or did I make a mistake somewhere?

I can’t get the module to work. I entered the free API key but no data is provided. I suspect a typo or setting that I am not doing correctly. I would appreciate your help with possible working examples. Thank you in advance for your efforts.

config:
            {
                // See 'Configuration options' for more information.
                weatherProvider: 'openweathermap',
                weatherEndpoint: '/onecall',
                apiKey: '57657657576',
                apiVersion: '3.0',
location:'Amsterdam,Netherlands'
                type: 'forecast',
                colored: true,
                fade: false,
                maxNumberOfDays: 3,
                degreeLabel: 'true',
                showWindDirectionAsArrow: 'true',
                decimalSymbol: ','
            }		},

@sdetweil

cd ~/MagicMirror
npm install node-ical@latest

This worked for me too thks.

@Sam-0
I’m a little further along in the problem. It is not specifically included in the MMM-CalendarExt3. I see that the default calendar has not been updated. Only after restarting the Rasperry Pi will the agenda update again.

Does anyone have an idea what this could be or what I can look at?

After updating MMM-CalendarExt3, the data is no longer updated. So I do see the old data, but if I make an adjustment in the agenda that week, you will not see it appear. Not until I restart the Raspberry. Then I see the data. It seems that the automatic update no longer happens.

Does anyone have an idea? I use the Outlook link. Or is there a setting with which I can influence the refresh of the data? If you need any specific information, please let me know.

Thanks for the effort.
