@p1lspeda sometimes the class references are not standalone

.cellWeather

the selector says when the element (in tree) has ALL these classes… then
if no spaces then if THIS element has ALL these classes

@sdetweil
I managed to figure it out.
Just had to play around with the font-size and now it’s as I like it,
Thanks for your patience.

sdetweil

@p1lspeda awesome

did you use the dev window?

When using the marque option, is there a way to get the event time to scroll with the title? I played with the marque lines in my custom.css but no luck.

sdetweil

@meshuggahn currently not, as they are two separate elements

Hi, I have made great progress on the calendar configuration and css customization but i seem to have stuck on some details, if someone could help me out.

i am trying to achieve 3 weeks total, current week on top.
i am trying to get 2 or 3 lines per event, in order to see more text of event titles. i have managed that but i see now that more than one event per day overlap one on top of the other.

you can see events ok on Jun 28,29 but overlapping at other days.
i would appreciate any help.

@chriskar weekIndex:0

should set the first week shown in mode week

sdetweil

@chriskar views and scenes were config options in calendarExt2, but are not used in Ext3

chriskar

@sdetweil said in MMM-CalendarExt3:

@chriskar views and scenes were config options in calendarExt2, but are not used in Ext3

so i remove views and scenes and use only the config part?

sdetweil

@chriskar correct

mode:week
weeksInView:3
weekIndex:0 //first week to see, -1 is last week, default

etc

chriskar

ok thanks, this worked fine!
what about the overlaping issue? css code is mostly AI generated so it probably has a lot of junk in

sdetweil

@chriskar i do not know on css
he provides lots of control, but wrap seems difficult

Hi,
I updated to MM 2.32 this morning and ever since then, I have noticed that the CW entry in my MMM-CalendarExt3 is stuck at “CW1”:

I assume the newest changes have something to do with it

Any idea if I can solve this or do I need to wait for a module update ?
Thanks

sdetweil

@p1lspeda I see the same bug, but not sure where it is

a temp fix is to add this line to the CX3 config section

          minimalDaysOfNewYear:1,  // week number of 1st week in your country (should be 0 or 1)

there was an open issue on this inthe CX3 repo
https://github.com/MMRIZE/MMM-CalendarExt3/issues/215

I posted this workaround there too

@sdetweil
Great.
Thanks for help (again!)

Hi folks,

Trying to get MMM-CalendarExt3 working on my Pi Zero W running MM v2.30.0 and running into an issue where the calendar is blank. Relevant config.js below:

{
   module: "calendar",
   config: {
      broadcastPastEvents: true,
      maximumEntries: 10000,
      colored: true,
      calendars: [
          {
               fetchInterval: 1* 60 * 1000,
               symbol: "calendar-check",
               name: "p_and_b",
               color: "rgba(255, 0, 0, 1)",
               url: "..."
          },
          {
               fetchInterval: 1* 60 * 1000,
               name: "cal2",
               color: "rgba(0, 0, 255, 1)",
               url: "..."
          }
       [
   }
},
{
   module: "MMM-CaendarExt3",
   position: "bottom_bar",
   title: "family dashboard",
   config: {
      mode: "month"
      instanceID: "basicCalendar",
      locale: 'en-US'
      maxEventLines: 5,
      firstDayOfWeek: 1,
      calendarSet: ["p_and_b", "cal2"]
   }
},

Can anyone help me understand why my monthly calendar is coming up blank and a workaround?

sdetweil

@kribbitykrab ok, this is worse on pi 0w

Ext3 gets the calendar events from the default calendar

the calendar module fetches each url separately and broadcasts the events to other modules if they want to use them

but EXT3 doesn’t want to flash redraw the cal each time a block of events show up

so it also has a

refreshInterval

take whatever events have arrived since last time and display ( default 30 minutes)

now there is another tuning thing
if it drew immediately on startup it would be empty, cause startup is faster than fetch. but EXT3 doesn’t know how many cal urls might supply events.
so there is the

waitFetch

config parm (default 5 seconds)
wait that long after startup before displaying any events
then next will be updateinterval

pi0w is SOOOOOOO slow ,no events arrive before waitFetch
so next time is updateInterval time

so you can adjust these some

you are probably
impacted by this bug too, timeout on the connection between front and back ends
see https://forum.magicmirror.builders/post/127456

kribbitykrab

@sdetweil As always, thank you for the response!

I added the pingInterval and pingTimeout lines to both MagicMirror/js/server.js and MagicMirror/js/socketclient.js as described in your link.

I have also moved my fetchInterval into the config portion of my calendar module as you requested, and increased it to 10minutes. I added a waitFetch of 10sec into my MMM-CalendarExt3 module config, along with a refreshInterval of 10minutes.

When I run MM now however, I am unable to reach localhost. I get an error on Midori booth that says Could not connect: Connection refused. Potentially something to do with the server.js and socketclient.js fiddling? Appreciate further guidance!

sdetweil

@kribbitykrab i think you made a typo

do

npm run server

Default CW display shows on desktop Firefox but not on Chrome/Electron when using the rpi as a display. It only show “CW 1” for each week.

Firefox shows the correct week number “CW 32” in this weeks case. My search-fu is not finding a fix for this.
