MMM-CalendarExt3

kribbitykrab

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?

@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

@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!

@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.

@sdetweil Awesome! Many thanks!

Is there a way to remove the space where a symbol would be only for calendars not using a symbol?

sdetweil

@almightyyoshi yes

add

classes:"........ some_arbitrary_string "
//like this
classes:"foo",

after the module: line
to the instance you dont want the symbols to show

then use

.arbitrary_string .symbol {
     display:none;
}
/*like this */
.foo .symbol {
     display:none;
}

sdetweil

I think you can add the caledar_name selector too
from the ext3 doc

.event` : Every event has this selector. Each event could have these class names together by its condition.
  - `.continueFromPreviousWeek`, `.continueToNextWeek`
  - `.calendar_{calendarName}`    <-------
