Simple(?) module to send a notification every x minutes?

[sdetweil]

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

And I’m assuming all modules get all the notifications?

yes, sendNotifications are broadcast to all modules

@sdetweil
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.

Unfortunately, BGSS is implementing suspend method to stop it’s timer. So when you page rotator hides BGSS, it’s timer doesn’t work.
If you have some knowledge of JS, you can make monkey-patch with MMM-ModuleMonkeyPatch to suspend method not to stop its timer.

Hmmm… That’s actually a good behaviour, in my case. If it’s not being shown, there’s no need to be changing the picture.

But even when it’s not suspended, i.e., the picture is shown, it doesn’t change if its interval is greater than the SendNotification interval.

If i disable SendNotification and manually switch to the picture (i.e., unsuspend BGSS), it will happily switch pictures every hour.

The module also implements “resume” method to reset timer, so if the module get shown, it may be reset.
But I’m not sure unless examining all three modules related.

[sdetweil]

@MMRIZE the sendnotification module implements both suspend and resume

[UncleRoger]

So a little more testing…

If the interval for BGSS is >= the interval for SN, BGSS never changes the image. That is, SN causes BGSS to be active so its timer should start and (assuming nothing else changes) it should switch pictures according to the set interval but it doesn’t.

If the interval for BGSS < the interval for SN, and BGSS is active, it changes the image as it should.

Suspending and resuming BGSS does reset its timer, but if it’s not suspended, and its interval is >= SN’s, then it doesn’t change the image.

[sdetweil]

@UncleRoger well there was a change I had to make to SN because pages was sending spurious resumes which caused timer resets

@sdetweil
I have the latest version. (I’ve also forked it to add a separate resetNotification but that’s not in place at the moment.)

Based on what I’ve read about setInterval, the two modules should not be interfering with each other and yet, they sure seem to be.

@UncleRoger
Can you share your forked version?
