MMM-NotificationTrigger transform payload

[corius]

by the title i mean the title of the individual calendar events. but ok then it doesn’t work that way. So again asked differently: is there a way to display upcoming calendar events via the alert module?

[sdetweil]

@corius said in MMM-NotificationTrigger transform payload:

upcoming calendar events

what does that mean? if I have 20 entries, u want 1 alert with 20 entries, or 20 alerts with 1 entry each?
or just today, or?

alert module is expecting a single line of text

[lavolp3]

@corius you need to have a look at how the payload looks. If it’s an array, you should be able to catch the title of specific elements by using something like payload.entries[n].title

[lavolp3]

@corius Considering you want to alert the next event happening in say 15 minutes, you could first check what event is in a range of the next 15 minutes, then take it’s title and alert that one. Can all be done inside the callback function you’ve shown above.

Is that what you want?

[sdetweil]

@lavolp3 actually payload IS an array
(from my system default cal)

0: {title: "M L King Day", startDate: "1579500000000", endDate: "1579586400000", fullDayEvent: true, location: "United States", …}
1: {title: "Valentine's Day", startDate: "1581660000000", endDate: "1581746400000", fullDayEvent: true, location: "United States", …}
2: {title: "Presidents' Day", startDate: "1581919200000", endDate: "1582005600000", fullDayEvent: true, location: "United States", …}
3: {title: "Good Friday", startDate: "1586494800000", endDate: "1586581200000", fullDayEvent: true, location: "United States", …}
4: {title: "Easter Sunday", startDate: "1586667600000", endDate: "1586754000000", fullDayEvent: true, location: "United States", …}
5: {title: "Mother's Day", startDate: "1589086800000", endDate: "1589173200000", fullDayEvent: true, location: "United States", …}
6: {title: "Memorial Day", startDate: "1590382800000", endDate: "1590469200000", fullDayEvent: true, location: "United States", …}
7: {title: "Father's Day", startDate: "1592715600000", endDate: "1592802000000", fullDayEvent: true, location: "United States", …}
8: {title: "Independence Day Holiday", startDate: "1593752400000", endDate: "1593838800000", fullDayEvent: true, location: "United States", …}
9: {title: "Independence Day", startDate: "1593838800000", endDate: "1593925200000", fullDayEvent: true, location: "United States", …}

so the js would be

payload[0].title 

for the title (cal subject) of the 1st cal entry

I found this by using the developers window (ctrl-shift-i), selecting the ‘Sources’ tab,
expanding the modules entry, and then the calendar entry to get to calendar.js

then knowing it is a notification,(notificationreceived) i searched (ctrl-f) for ‘sendnotification’
I put a stop on that line, hit refesh(f5), and the web page starts over, and stops on that line, then use the mouse to hover over the eventlist variable name, and it expands to the data layout

[corius]

@lavolp3 yes that is exacly wat i want. can you please post the code? Thank you

[lavolp3]

{
  module: "MMM-NotificationTrigger",
  config: {
    triggers:[
      {
        trigger: "CALENDAR_EVENTS",
        fires: [
          {
            fire:"SHOW_ALERT",
            payload: (payload) => {
              var testMessage = "";
              payload.forEach(event => {
                if (moment(event.startDate) > moment() && moment(event.startDate) < moment().add("15", minutes)) {
                 testMessage += event.title + ", "
                }
              });
              return {
                      type: "notification",
                       title: "test",
                       message: testMessage
              } 
            },
          },
        ],
      },
    ]
  }
},

This will most probably not work and needs to be de-bugged, but might be worth as a starting point. And I hope you get what I’m hinting at.

@corius

can you please post the code?

Took me 10 seconds :smiling_face_with_sunglasses:
No, of course I was already working on it.

Seriously, I like the idea, that’s why I did a contribution.But you need to be more specific if you want to have the complete solution

[corius]

@lavolp3 Thank you for the fast answer. I tried this code. the result is that I get a notification but so far it only contains the title (test) but not the massage (title of the calendar event)

[corius]

@lavolp3 what do you mean by “more specific”?

[sdetweil]

@corius did u have an event within the next 15 minutes?

[sdetweil]

@corius >what do you mean by “more specific”?

all the questions we have been asking… title, time filter, number to show, …

[corius]

@sdetweil yes i have

[lavolp3]

@corius Well to be honest I did not expect it to work from scratch. But I am considering taking this into my own mirror to remind me of taking out the trash. :smiling_face:
I won’t get it done today.
If you don’t know how to work on from here I need to ask for your patience, and I’ll have a closer look at it myself in the next days.

[sdetweil]

@lavolp3 i am debugging it now

not making any progress… can’t get the time compare to work

let now = moment()
let end = now.add(15, "minutes")
let event_time=moment(event.startDate)
if(event_time.isAfter(now) && event_time.isBefore(end))

its 11:53, event starts at 12:00 and ends as 12:15

so 12:00.isAfter(11:53) should be true, but is false
and 12:00.isBefore(12:08), should be true,m but is false

I think it’s better to build a new module about alerting events by the condition.

[corius]

@lavolp3 @sdetweil thank you for the time you have spent so far. I would be happy if someone else has an idea how to implement it. Thanks:smiling_face:

[lavolp3]

@corius So I tamed the beast but I’m getting the feeling that @Sean is right.

The following would alert you of the next event every time the calendar sends a calendar_event notification:

	{
	  module: "MMM-NotificationTrigger",
	  config: {
		triggers:[
		  {
			trigger: "CALENDAR_EVENTS",
			fires: [
				{
					fire:"SHOW_ALERT",
					payload: (payload) => {
						var testMessage = "";
						var nextEvent = payload.find(event => event.startDate > moment().format("x"));
						testMessage = nextEvent.title + " " + moment(nextEvent.startDate, "x").format("HH:mm");
						return {
							type: "notification",
							title: "Next event:",
							message: testMessage
						} 
					},
				}
			],
		  },
		]
	  }	
	}, 

For some yet unknown reason, I am getting this alert 8 times! The alert then vanishes quite shortly after.

It is a good idea, but what I would do, no, WILL do, is implement a “Notification Alert Function” directly into the calendar module (or into MMM-CalendarExt, if you’re interested, @Sean).
I think that would be a better way of ontrolling the alert created from a calendar event appearing.

@lavolp3 said in MMM-NotificationTrigger transform payload:

because it still sends an alert notification, with an empty payload

fire:“SHOW_ALERT”, (always)

[lavolp3]

@sdetweil As far as I understand, it triggers when receiving the CALENDAR_EVENTS noti, and then “fires” a new notification, which is the “SHOW_ALERT” with the new payload.
This does not explain to me why it sends the “SHOW_ALERT” noti apparently 8 times in a row.
