How to configure MMM-Buttons to start/stop MMM-Podcast2

Fozi

Hi there!
I’ve been lurking here for quite some time and found many helpful hints, while I’m building my first MagicMirror. Thanks for that to all!

What do I want to accomplish?
I have following modules installed, which all run without problems:

MMM-Remote-Control
MMM-Podcast2 (which starts the “tagesschau in 100 min.” video stream
MMM-PIR-Sensor (to switch my monitor on and off)

Currently, I can start/stop the video stream when I enter http://myIP:8080/remote?action=NOTIFICATION&notification=BUTTON_PRESSED in a browser.

Now I want to accomplish following user stories:
Story 1:
Press shortly a physical push-button on pin 27 to start/stop the video stream.
This button is also a combined restart/shutdown button.
Press > 2 sec --> Reboot
Press > 5 sec --> Shutdown
I am using this simple service.
Now I want to use the same button to start/stop the video stream, when I push it for less than 2 secs.

Story 2:
When the PIR sensor detects motion and switches on the monitor, the video stream should start, too. Stopinfg the video by pressing shortly the physical push-button (see Story 1)

I’ve installed MMM-Buttons, but I can’t find the right configuration of the MMM-Buttons module to at least start/stop the video.
What is the correct payload and notification I have to use?

I hope that some could give the hint into the right direction.

Thanks in advance,
Fozi

Alright, I found the solution myself, at least how to trigger play/stop with a push-button:

I wasn’t aware that connecting GND and a GPIO Pin like BCM 27 will not trigger reliably anything as the status is floating, Thus a pull-down resistor is required to get a defined high status. Check this really comprehensive write-up:
link text.
So I added a resistor as gescribed, e.g. here:
in chapter 4.2.
Then I configures the MMM-Buttons module that way:

{
	module: 'MMM-Buttons',
		config: {
 		buttons: [
 		{
  		pin: 27,
 		name: "podcast",
		shortPress: {
		notification: "BUTTON_PRESSED",
		
		},
		
           }
        ]
    }
},

That’s it!

When I now push the button the video stream start shortly after playing, and when I push again, it stops.

The one thing I’m still trying to accomplish is that the PIR-sensor (AM312) on pin 4 triggers the video to start.

I home this helps some of you, when you come by.

Cheers,
