@siujd2001 you hadn’t mentioned anything about screen.

I recently switched to using start:wayland also and found that in MMM-Pir, the ddcutil mode worked best. Screen control in general seems to vary on RPi depending on the monitor you have.

@siujd2001 in your config you have:

Pir: {
  mode: 1,
  gpio: 21
//   gpio: 4 // <–connected to 4
}

Did you try with mode: 0 ?

Mode 1 uses an external python script and since that’s an external executable, there’s always a chance that the script has locked up the GPIO so when you start MMM-Pir again, it tries to start a new version of the script.

I’m starting to mess around a bit with a custom module and I’d like it to be able to override some styles from an existing 3rd party module.

I know the following options work:

• use custom.css
• put my module after the existing module in config.js

But if I ever wanted to release this module, I’d want it to be able to override the existing css content no matter what order it is put in the user’s config.js.

I was tracing through loader.js and found that bootstrapModule loads the styles for a module but there doesn’t appear to be anyway to delay/reorder this. Then I followed through into main.js and I see that there’s a notification for ALL_MODULES_STARTED but this seems like it’s “too late” to modify the css order.

@sdetweil thanks for the fix! I really appreciate your effort.

Just in case it’s useful for someone else who runs into the same problem, with the fix applied and my calendar configuration that worked in 2.29.0, I see:

[Debug] [Calendar] self update (calendar.js, line 950)
[Debug] pushing 18 events to total with room for 10 (calendar.js, line 695)
[Debug] events for calendar=10 (calendar.js, line 697)
[Debug] pushing 246 events to total with room for 10 (calendar.js, line 695)
[Debug] events for calendar=20 (calendar.js, line 697)
[Info] sorting events count=20 (calendar.js, line 699)
[Info] slicing events total maxcount=10 (calendar.js, line 739)

And when I set a new maximumEntries per calendar I get:

[Debug] pushing 34 events to total with room for 50 (calendar.js, line 695)
[Debug] events for calendar=34 (calendar.js, line 697)
[Debug] pushing 295 events to total with room for 500 (calendar.js, line 695)
[Debug] events for calendar=329 (calendar.js, line 697)
[Info] sorting events count=329 (calendar.js, line 699)

This does result in a different behaviour for users of other calendar modules as of 2.30.0 so might be handy if the authors could update their recommendations in their documentation?

@sdetweil thank you for supporting the calendar module!

For my specific use case, I don’t display the default calendar module, it’s just used to fetch and broadcast events for CalendarExt3. With this in mind, the idea of a sliding window centered on a date (today in most cases) makes the most sense to me.

Is there a reason why the default for maximumEntries is 10? I had assumed performance but it looks like this is actually what’s used to control the number of events displayed.

@sdetweil I saw your note in the other thread about setting maximumEntries per calendar. I guess it means with this change there’s more thought required to determine the “right” values for each of the calendars you want to add.

Example: As of today, Jan 2, this configuration for the calendar will show the “New Year’s Day” event on CalendarExt3:

config: {
	broadcastPastEvents: true,
	calendars: [
	{
		url: "https://ics.calendarlabs.com/39/f7480acf/Canada_Holidays.ics",
		name: "can_holiday",
		maximumEntries: 16,
	},
},

The following configuration will not show the “New Year’s Day” event:

config: {
	broadcastPastEvents: true,
	calendars: [
	{
		url: "https://ics.calendarlabs.com/39/f7480acf/Canada_Holidays.ics",
		name: "can_holiday",
		maximumEntries: 15,
	},
},

If I set maximumNumberOfDays: 180 then it actually changes the start date of the event array sliding window and the “New Year’s Day” event will show if maximumEntries: 15.

Which makes me realize that the combination of:

broadcastPastEvents: true,
maximumNumberOfDays: 365, // default value

will actually return 2 years worth of events (assuming you don’t exceed the maximumEntries setting).

@sdetweil I can confirm that setting maximumEntries:100 allows events to show on CalendarExt3 for the specific “Holiday” calendar in my test config.js.

However, there’s something else that is coming into play. If I switch to a very busy calendar (300+ events) I actually get nothing showing up in CalendarExt3 but I can see that the events are in the calendar module. I used @MMRIZE eventPayload hook to dump to console and the events I’m getting start in Jan 2024.

Note: I switched to maximumEntries:20 for this test.

I then set broadcastPastEvents:false and I still get events from Jan 2024.

if (typeof module !== "undefined") { module.exports = config; }

Today (Jan 1) should have a full day event on CalendarExt3 for New Year’s Day (as seen in top right calendar output).

@sdetweil thanks for looking at this. I’d love to see an error of some sorts - much easier to track down! :)

I’ll strip down to a basic config.js and see if I can find something that works for me and maybe that will give some clues.

@sdetweil I get what’s in the screenshot in the console but CalendarExt3 is loaded in the browser correctly.

Note that this looks identical to what I see when running 2.29.0.
