MMM-CalendarExt3 only one calendar not updating

MMRIZE

maximumEntries: 4,

Hmmmm… I think you’d better increase this value more.

@oquendo421 said in MMM-CalendarExt3 only one calendar not updating:

updating without a force refresh.

have you waited over 30 minutes?

if so, the update came after the initial Ext3 wait period (he doesn’t know how many calendars will be broadcasting… (and the timing changed on the updated cal code)

and before the refreshInterval (30 minutes)

refreshing the page does NOT fetch the calendar data, but DOES cause the rebroadcast

the output on npm start will show the two messages… if using pm2 those lines have timestamps, so you can tell how long between
(I think he waits 5 seconds)

I have this same problem with Ext3Agenda - manual refresh always works.

Sometimes waiting works - I’ve waited for 4 hours and suddenly have items appear. Waiting for refreshInterval doesn’t work - I can see the module/refresh with no data even though the calendar has broadcasted the items.

My current workaround is to wait for a few minutes and then use MMM-RemoteControl to connect and refresh the browser using that module, which in my experience works 100% of the time

sdetweil

@emlowe i don’t understand what the underlying issue is here yet.

page refresh sends the same data already available…

emlowe

Yea, it’s a mystery to me as well - I just know doing the manual refresh works very reliably.

I’ve had this problem on a stock pi3 b and a pi3 a+ - initially, I thought it was related to the low memory issues on the pi3 a+ - but as I update to use this new module from older ones I’ve seen it again on a stock 4gb pi3

sdetweil

@emlowe its clearly a timing issue… multiple people have encountered it…

I think you can change the waitFetch value up , depending on the time between fetchs as shown in the pm2 logs…

emlowe

Was out for a week - some more details:

Here are relevant log entries:

So that was about a minute to broadcast the first time, and then it follows the refresh interval reasonably closes.

I have the Ext3 module waitFetch set to 5 minutes (5 * 60 *1000) - well after the first broadcast. When the Ext3 module draws after 5 minutes, there is nothing in it, and it is empty with no events whatsoever. It’s like it has no data at all.

I have the Ext3 module refreshInterval set to 7 minutes (7 * 60 * 1000) - after the 7 minutes the module will refresh and it remains empty despite the calendar having done two broadcasts. The Ext3 module will remain empty for hours.

However, if I manually refresh the browser using the remotecontrol module - the Ext3 module takes 5 minutes to appear (based on waitFetch but will have all the data)

@emlowe waitfetch is from CalendarExt3 start to latest broadcast

i cannot see start but latest is at 11:01:33

find start time and subtract. add a couple seconds for variability

his default waitfetch is 5 SECONDS

Then after that, next screen refresh is at updateInterval time

also 23 events seems small, if this is mm v2.23.0, you did put on the clipping fixes right?

is this the SAME calendar broadcasting?
then to its first broadcast from ext3 start

emlowe

I am on the develop branch

The entire start is at 10:54:23

[2025-01-27 10:54:23.207] [LOG] Starting MagicMirror: v2.31.0-develop

I’m not sure when Ext3Agenda starts as there is no log item specific to that afaik - but I assume it’s sometime around:

[2025-01-27 10:54:26.290] [LOG] No helper found for module: MMM-CalendarExt3Agenda.

so Ext3 start is no earlier than 10:54:23 and the first broadcast was at 10:55:44 - this is much less than the 5 minutes I have manually configured for waitFetch.

(in other words, I am waiting much longer than should be needed, but it does not work unless I manually refresh)

The log at 11:01 is the second broadcast of the same calendar

I am only pulling 5 days of data and not broadcasting past events, 23 is correct.

module: "calendar",
hiddenOnStartup: true,
position: "top_left",
config: {
    broadcastEvents: true,
    broadcastPastEvents: false,
    maximumNumberOfDays: 5,
    maximumEntries: 100,
    fetchInterval: 5 * 60 * 1000,
    calendars: [
    {
        name: "family",
        URL: "<redacted>"
    }
    ]
}

module: "MMM-CalendarExt3Agenda",
position: "top_left",
config: {
    showMiniMonthCalendar: false,
    firstDayOfWeek: 1,
    startDayIndex: 0,
    endDayIndex: 0,
    calendarSet: ['family'],
    waitFetch: 5 * 60 * 1000,
    refreshInterval: 7 * 60 * 1000,
}

@emlowe ok, in the case of modules that only have a browser component ( no node helper) then
starting application message is the start time

another use just resolved the same issue w waitfetch, but he had multiple calendars

emlowe

Further strangeness.

Let’s say I change waitFetch to something that shouldn’t work (eg 5 seconds) - clearly, this doesn’t work since the first broadcast is after a minute or so.

But if I manually refresh the browser as soon as I see the log entry about the broadcast - everything appears just fine.

So for example, setting

waitFetch: 5 * 1000,
refreshInterval: 2 * 60 * 1000,

Nothing will appear in the calendar - not at start (expected) and not after 2 mins (1 refresh), or 4 mins, or 10 mins or however long I want to wait - nothing.

But if I manually refresh - everything appears right away as long as I refresh after the broadcast log line

sdetweil

@MMRIZE will have to advise. this is the depth of my knowledge

i work on the default calendar
well, one thing
when you refresh the page, all the modules web components are reloaded. the default cal sends a request to its node helper to get events. and it has them already, so sends immediately

and of course because the default cal will be shown, its shows with the correct events, right??

emlowe

Yea, I believe the default calender is working and broadcasting correctly - not sure exactly where Ext3Agenda is having problems - but I have a few ideas I plan to try out.

emlowe

Bah! I have to apologize - I was on the develop branch but apparently, I was some commits behind and I think I was missing the commit that fixed the “clipping” problem

I made sure to update to the head of develop and things are working much better now. So it seems all along it has been the known issue

Doh!

emlowe

Actually have to take this back. Currently testing running in server only mode and a browser so I can see the console easier

When I see in the log this line:

[2025-01-27 13:52:24.893] [INFO] Calendar-Fetcher: Broadcasting 22 events from <redacted>

I can say that modules are NOT getting any calendar notifications, despite this log entry. They are not broadcast. I added some code to Ext3Agenda to print out when it gets any notification, and it never gets any CAL items. (I see it getting DOM_CREATED, DOM_UPDATED, etc,etc)

I see in the console log the following:

sorting events count=0
slicing events total maxcount=100

which seems odd given that the helper reported broadcasting 22 events. Those items repeat in the console log , but it’s always sorting events count=0

UNTIL I refresh the browser - Now I see the Ext3Agenda module getting CALENDER_EVENTS and sorting events count=22

emlowe

I guess I should have run some tests with just the standard calendar module.

Now just using the standard calendar module - and it just says “Loading” despite having also printed “Broadcasting 22 events from”

sdetweil

@emlowe as you updated to the develop branch, did you also redo the npm run install-mm

emlowe

I did yes - so the current test results are this

The calendar did eventually appear - but it took quite some time - I wasn’t watching, so I don’t know when exactly - I’ll test again. But it was several minutes after the log output of “broadcasting 22 events”

sdetweil

@emlowe the default for ext3 is 30 mins
if missed at waitFetch

only see the timing in
pm2 log

default calendar working, right?

emlowe

@sdetweil No, I’m stopped testing Ext3 and I am only testing the default calendar.

it is not working - I see Loading... for some number of minutes or hours, I haven’t determined any consistency. This test run is now past 45 mins and it still says Loading… despite having broadcast the events 9 times:
