Do modules each have their own timer or does resetting the timer in one module affect another?

I ask because I have MMM-BackgroundSlideshow set to change pictures each hour and MMM-SendNotification set to send a notification to MMM-Pages to switch to page 1 every 5 minutes. But in this setup, the picture never changes. My hypothesis is that when SendNotification resets the timer after 5 minutes, that affects BGSS which then never gets to 1 hour to switch to the next picture.

If I change BGSS to change pictures every 1 minute (or less than 5 minutes), the picture does change as expected.

Mind you, it’s probably something I’ve done that’s screwed it up, but I figured I’d ask about this first just to eliminate it as the source of the issue.

@sdetweil
I made that change and it does indeed work as I’d hoped. This is totally awesome!

Thank you!

@sdetweil
You truly are amazing!

Am I right in thinking that if I change this:

      } else if(topic==this.config.notification){

to this:

      } else if(topic==this.config.resetNotification){

and put this in the config:

resetNotification: "DIFF_NOTIF",

in addition to the notification: setting, then I can have it reset when a different notification is received? And I’m assuming all modules get all the notifications?

This would be so that if someone comes up and pushed the button to switch to the info display close to the end of the timer, it will reset it so they have time to look at what they want.

@sdetweil
That worked! Thank you so much!

Now I am just being cheeky but if you are bored and want to add a feature, it would be great to be able to reset the timer based on a notification. (In my case, if MMM-Keypress sends a PAGE_INCREMENT notification to change pages, restart the timer from that point.)

Anyway, I am getting really close to having everything the way I want it and am hoping that I can build an actual frame for the mirror and mount it next week and I couldn’t have done it without all your help (and so many others, like @MMRIZE and everyone who wrote the modules I’m using.) So, really, thank you!

As a heads up, MMM-SFMuniBusTimes (https://github.com/vikramraja1995/MMM-SFMuniBusTimes) no longer works due to Muni switching APIs. I’ve looked at it and have info about the new API but, honestly, I’m like a bumblebee in the deep end of a swimming pool.

@sdetweil
I switched to your fork and while it’s better, it’s still sending a notification every several seconds.
Here’s my config:

		{
			module: "MMM-Pages",
                        classes: "fixed",
			config:	{
				modules:[	[ "page1" ],
							[ "page2" ],
						],
				fixed: [ "fixed" ],
				rotationTime:	10000,
				animationTime:	10000,
			}
		},

and

        {
            module: 'MMM-SendNotification',
            classes: "fixed",
            config: {
                interval: 3600000, // 1 minute interval
                notification: 'PAGE_CHANGED',
                payload: 1,
            },
        },

(I upped the interval to see if that would do anything. It didn’t.)

I’ve commented out all the other modules except the clock, MMM-BackgroundSlideshow, and MMM-ViewNotifications.

@sdetweil
I’ve no clue how to run it the way you did with the stop and all, but I did start commenting out modules and it seems that MMM-pages is the culprit.

Without it, SendNotification works fine but when it’s active, SendNotification sends multiple notifications per second:

It may be that MMM-pages is suspending and resuming MMM-SendNotification with each change, even though it’s set as “fixed”, and maybe that’s triggering it?

It may be that this is just something that won’t work for me.

I really appreciate your help!

@sdetweil
This is what I have:

{
  module: 'MMM-SendNotification',
  position: 'top_right',
  classes: "fixed",
  config: {
    interval: 60000, // 1 minute interval
    notification: 'PAGE_CHANGED',
    payload: 1,
  },
},

Thank you for your patience and assistance! You are amazing!

@sdetweil
Got the new version (typo in “notification”?) and it seems to work except that it ignores the interval and just constantly sends the notification.

Also, there’s an error showing in the console log:

Parameter mismatch in module.show: callback is not an optional parameter! 3 module.js:394:8

with different numbers. I’m not sure that’s a problem (MMM-BackgroundSlideshow has the same error and it works fine) but I thought I’d mention it.

@sdetweil said in Simple(?) module to send a notification every x minutes?:

https://github.com/sdetweil/MMM-SendNotification

Thank you so much! That got a lot farther than I ever did. When it gets to the point of actually sending the notification, however, I see an error in the browser console:

sendNotification: Notification should be a string.

As far as I can tell, the notification (this.config.notification) is a string. Is there something else that I can do to force it to be considered a string?

Note: the only change I made was to add a bunch of console.log messages so I could try to understand what was going on and then, when I saw that error, commented out the sendnotification line (which made the error disappear). When I uncommented it, the error came back.
