MMM-CalendarExt3 and MMM-MonthlyCalendar blank

sdetweil · Mar 20, 2025, 4:16 PM

@Scott-M I don’t know… I just re-enabled my ext3

my ext3 config

      {
        module: "MMM-CalendarExt3",
        position: "bottom_bar",
        disabled: false,
        order: "*",
        hiddenOnStartup: false,
        configDeepMerge: false,
        animateIn: "None",
        animateOut: "None",
        config: {
          eventFilter: (ev) =>  {
 return true 
},
          eventTransformer: (ev) =>  {
 return ev 
},
          manipulateDateCell: (cellDom, events) =>  {
},
          weatherPayload: (payload) =>  {
 return payload 
},
          eventPayload: (payload) =>  {
 return payload 
}
        }
      },

note this is output from MMM-Confg setting all the extra options

Thanks for posting that but even with that config it is still blank. I have to leave it for now but will start on it fresh tomorrow and rebuild it and see what happens. Hopefully it is just something simple I missed.

I wasted most of today writing new Pi images to new SD cards, using the script to install MagicMirror again, only to have it crash / hang on the [LOG] Starting server on port 8089 … message every time.

I gave up and went back to my working SD card and it seems to work now. I had been using this from some sample code I found online, just to test and get the MMM-CalendarExt3 module working

{
		url: "webcal://www.calendarlabs.com/ical-calendar/ics/76/US_Holidays.ics",
		name: "holiday",
		fetchInterval:  60000,
},

I decided to add a couple of other calendars in and all of the others I tried show up in the Ext3 view, except this one. Not sure what the problem with it is but I won’t be using it so will move on.

I now have 4 random calendars and the code above in the calendar module and they all work, except the US_Holidays, the events for that one show in the list view but not in Ext3.

Thank you for taking the time to reply and help, sorry it seems to have been a bit of a waste of time.

@Scott-M just fyi, we replace webcal: with https: under the covers…

I’d like to know more about the system hang…

what OS, what UI engine (x11 wayland vs labwc)
note we added new start commands for the different engines…

see https://forum.magicmirror.builders/topic/19269/new-magicmirror-start-options-in-version-2-30-0

 [LOG] Starting server on port 8089

if you are doing npm run server, that is the end of the messages
until a browser connects… (it might LOOK like a hang… but its just waiting)

IF the installer detects that electron did not install for some reason (armv6, or …)
THEN it sets up my script (run-start.sh) to run browser over server
( you can check by examining the start: clause in package.json)

and ASSUMES
chromium is the browser..

the end of the scripts web page explains how to use some other browser

if chromium is not found, an error message will be logged in the npm start output, but nothing will be shown on the screen

now, in ANY case, did you install the clipping fix?
see https://forum.magicmirror.builders/topic/19282/version-2-30-0-calendar-fix-for-clipping-broadcast-event

which accidentally chopped off the messages sent to ext3 (and others)
my fault… it passed test

60 seconds to fetch holidays will trigger a block on calendarlabs as they warned us a couple years ago about being pounded by hundreds of mirrors getting content too often (we changed that fetch to once a week)

ext3 is designed to NOT flash the screen on every update… all calendars are processed concurrently but independently and broadcast when they have data.
ext3 wants to WAIT til all the data has arrived, (waitFetch config time, 5 seconds by default)

IF the data does NOT arrive for A calendar before waitFetch, THEN it will NOT BE DISPLAYED until the refreshInterval time (default 30 minutes)
(or you MANUALLY refresh the page (ctrl-r))

Back to the SD card that hangs on the starting server message…

I used Raspberry Pi OS (64 Bit) Bookworm, onto a Pi5, labwc compositor. I did install the clipping fix after the MagicMirror install

I ran with

npm run start

with this result, it may just be waiting but CRTL C does nothing and I have to close the ssh connection and reconnect.

@Scott-M ok, starting server is correct…

did you npm install or npm run install-mm
after installing the clipping fix?? (its required)

@sdetweil said in MMM-CalendarExt3 and MMM-MonthlyCalendar blank:

@Scott-M ok, starting server is correct…

I see, my mistake. I assumed from the forum post that this was if you use the development branch, as the instructions said

cd ~/MagicMirror
git fetch origin pull/3679/head:_fix_clipping
git switch _fix_clipping
# if you get an error error, rm package-lock.json
# and repeat the git switch
restart MM

with npm run install-mm further down the post. I must have done this on the older one I am using though as it works.

Away all weekend so won’t be able to check until Monday.

Thanks again!

Scott-M · Mar 25, 2025, 9:49 AM

Just to pick back up on this, I checked my bash history and I did npm run install-mm after the clipping fix.

I have tried a few times now to do this with the same result, this time without the clipping fix.

Reflashed the image and then the following steps are my bash history from first run of the OS. Only change to the config file is changing the port and the full whitelist. I selected No to the pm2 question, the screensaver was not disabled, just a waring about not knowing how to disable on an labwc compositor.

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"
cd ~/MagicMirror/config
nano config.js
npm run start

With the following results, MagicMirror doesn’t start. and doesn’t get any futher that the whitelist warning. Same result without the full whitlist though…

Would be useful is someone can replicate this and see if it is something peculiar to my enviroment.

Raspberry Pi5 with 64 Bit Debian Bookworm with desktop.

I am just about to try with the 32 bit image but the whole process takes a while.

Update: couldn’t get it to install on the 32 bit version. New install of 32 bit bookworm, ran the install script and it fails with:

installing correct version of node and npm, please wait
/usr/local/bin/n: line 753: /usr/local/bin/node: cannot execute: required file not found
bash: line 309: /usr/local/bin/node: cannot execute: required file not found
node failed to install, exiting

sdetweil · Mar 25, 2025, 1:07 PM

@Scott-M i will examine and fix the installer

32bit on pi5 might never run as there were conflicting hardware changes

can you try to start for wayland?

npm run start:wayland
