finally got it working with

		 {
				module: "calendar",
				header: "Abfallkalender",
				position: "top_left",
				config:
					{
						calendars: [
							{
									url: "https://calendar.google.com/calendar/ical/...group.calendar.google.com/private-.../basic.ics",
	                                maximumNumberOfDays: 14,
	                            	maximumEntries: 5,
							},
						],
					},
		},

openweathermap.org offers values for the air pressure. Could it be possible to include this to the core currentweather module?

I cant get maximumNumberOfDays working, tried several things like putting it in front of the config, in the config or after the config, days as number or string, nothing worked for me. My last config:

		 {
				module: "calendar",
				header: "Abfallkalender",
				position: "top_left",
				config:
					{
						calendars: [
							{
									url: "https://calendar.google.com/calendar/ical/...group.calendar.google.com/private-.../basic.ics",
							},
						],
					},
 				maximumNumberOfDays: '7',
		},
