MMM-CalendarExt3
-
Hi,
I’ve just come across this great module, but I cannot quite get it to work.
My default calendar module shows multiple google-calendar based calendars/entries.
This works fine.
However: CX3 only shows the ‘work’ calendar and I do not know why.Can anybody point me in the right direction ?
Edit: so I got it working (somehow) but the calendar entries take forever to show up in CX3.
Why is that ?[2025-02-07 12:31:47.169] [INFO] Calendar-Fetcher: Broadcasting 12 events from https://calendar.google.com/calendar/ical...

[2025-02-07 12:31:56.453] [INFO] Calendar-Fetcher: Broadcasting 93 events from https://calendar.google.com/calendar/ical...Thanks
my CX3 config:
{ module: "MMM-CalendarExt3", position: "bottom_bar", title: "", config: { mode: "week", weekIndex: "0", weeksInView: "2", instanceId: "basicCalendar", //locale: 'de-DE', maxEventLines: 8, firstDayOfWeek: 1, calendarSet: null, } },my default calendar module config:
{ module: "calendar", position: "bottom_right", header: "Calendar", config: { broadcastPastEvents: true, colored: false, coloredSymbolOnly: false, maximumEntries: 8, maxTitleLength: 50, maximumNumberOfDays: 180, timeFormat: "relative", getRelative: 60 * 24, urgency: 60, calendars: [ { url: 'https://calendar.google.com/calendar...', symbol: 'calendar', // MAINZ 05 CALENDAR name: 'mainz05', colour: 'white', }, { url: 'https://calendar.google.com/calendar...', symbol: 'calendar', // MAIN GOOGLE CALENDAR name: 'personal', colour: 'white', }, { url: 'https://calendar.google.com/calendar...', symbol: 'calendar', // FORMULA 1 CALENDAR name: 'f1', colour: 'white', }, { url: 'https://calendar.google.com/calendar...', symbol: 'calendar', // EB MAINZ name: 'eb_mainz', colour: 'white', }, { url: 'https://calendar.google.com/calendar...', symbol: 'calendar', // PRO RUNDE name: 'pro_runde', colour: 'white', }, { url: 'https://calendar.google.com/calendar...', symbol: 'calendar', // BUSINESS TRIPS name: 'work', colour: 'white', }, ], }, }, -
@p1lspeda i would start with commenting out the calendarSet:null
-
@sdetweil
thanks for the help.
Did that - no change.
Same problem and I have no idea where to start an lookEdit: HA ! I decreased the refreshIntervall and it seems as that did the trick - I could have probably just waited 30min (but I’m impatient)
-
@p1lspeda ok. nice work.
Ext3 attempts to not flash the screen on every update. the individual calendar data arrive at different timesso the waitFetch value is used to decide when to display initially, and refreshInterval after that
waitFetch defaults to 5 seconds
so this means some data arrived after 5 seconds (waitFetch)

Re: MMM-CalendarExt3
Next (easy) question:
My CX3 module doesn’t have symmetrical borders (left & right), i.e. the left border is smaller than the right border.
I want to maximize the width or at least have symmetrical borders.
Border = distance between module edge and display edge
See the screenshot:

How can I adjust these in my custom.css ?
My custom.css includesbody { margin: 10px; position: absolute; height: calc(100% - 30px); width: calc(100% - 30px); }A hint/clue/idea would be very much appreciated.
Thanks ! -
@p1lspeda we already set margins and borders
see css/main.csssounds like your 7 day width is not symmetrical to the position the module is in
CX3 has extensive classes that should allow you to position it properly
also your css entry whacks the entire page, not just your module config.
see the position layout in the doc here
html is typically reading anchored left for ltr langusgrd abd right for rtl langusges, so you should br able to increase the left edge number to shift the whole image right
.CX3 { left:20px; }this left is relative to its configured position
-
@sdetweil Thanks for pointing me in the right direction.
Seems I need to play around with css. -

I just did a new build of my MM to upgrade to Bookworm and update to no longer use unsupported modules. Everything went well for the most part except my calendars aren’t showing. This is in the Error log from start up -

@gonzonia if you installed MagicMirror 2.30
did you also install the fix? -
@sdetweil No. I had not seen that. Installing now. Thanks!

Would it be possible to combine the calendar color indicator at the time using just CSS?
Right now, it’s a colored circle and the time next to it and I was wondering if it would somehow be possible to have the time be inside the circle, or have the time be a different background color.
My display is quite small, and saving a few extra pixels would be nice.
-
Hello.
Is it possible that with the Calender-ext3 in the weekly display the calendar entries are displayed in two or three lines? -
Hello everyone
I hope you can help me. I’m trying to get the calendar to display in Calendar Ext3.
This is what my configuration looks like
{ module: "calendar", position: "top_left", config: { broadcastPastEvents: true, // <= IMPORTANT to see past events calendars: [ { url: "https://calendar.google.com/calendar/ical/....................ics", name: "Andreas", // <= RECOMMENDED to assign name color: "red" // <= RECOMMENDED to assign color } ] } }, { module: "MMM-CalendarExt3", position: "bottom_bar", title: "", config: { mode: "month", instanceId: "basicCalendar", locale: 'de-CH', maxEventLines: 5, firstDayOfWeek: 1, calendarSet: ['Andreas'], } }, -

Great, it worked. I have one more question.
Do I have to use the “calendar” module from MagicMirror, or would the MMM-MyCalendar module also work?{ module: "MMM-MyCalendar", position: "bottom_right", // This can be any of the regions. Best results in left or right regions. header: 'Kalender Andreas', config: { colored: true, maxTitleLength: 30, maximumEntries: 4, displayRepeatingCountTitle: true, timeFormat: "HH:mm", dateFormat: "DD:MM:YYYY", joiningWord: "um", calendars: [ { url: 'https://calendar.google.com/calendar/ical/................./basic.ics', color: "#5b53d4", symbol: 'calendar', auth: { user: 'username', pass: 'superstrongpassword', method: 'basic' } }, ], } }, { module: "MMM-MyCalendar", position: "bottom_right", // This can be any of the regions. Best results in left or right regions. header: 'Kalender Daniela & Andreas', config: { colored: true, maxTitleLength: 30, maximumEntries: 4, displayRepeatingCountTitle: true, timeFormat: "HH:mm", dateFormat: "DD:MM:YYYY", joiningWord: "um", calendars: [ { url: 'https://calendar.google.com/calendar/ical/................./basic.ics', color: "#f05db0", symbol: 'calendar', auth: { user: 'username', pass: 'superstrongpassword', method: 'basic' } }, ], } }, -
@CyruS1337 MAYBE it will work, but it is a clone of the default cal from 3 years ago, with the broken repeating schedule code…
which I just fixed in the latest release 2.30.0, Jan 1… -
@sdetweil thanks a lot. It works

Hi,
CSS is driving my crazy.

As you can see in the above screenshot, today (Tuesday) the top (weather, today’s Date & Month) take up the entire width.
This is fine.
The “problem” was yesterday with the additional “CW13” which led to overlapping.
I was wondering; if I could minimize the padding around the current date (the red area in the screenshot), theoretically the space should be big enough for all info to be next to each otherI tried adjusting the css
.CX3 .today .cellDate { padding: 1px 8px; }but unfortunately, that did not have any effect.
Can somebody point me in the right direction ?
Thanks -
@p1lspeda I do not know , but you can use the developers window to fiddle with css changes live
see the second link in my signature below
also see this topic where we discussed css and the dev window just a couple days ago
