MMM-Buttons

Johans

Hi, I wanted more pages on my mirror and control them physically with a button.
installed MMM-Pages / MMM-Page Selector / MMM-Buttons and MMM-Remote Control.
(First I tried to use MPR-121 but that gives too many errors during installation so I gave up)
3 buttons connected to Pin 23-34-25 (BCM numbering - RPI-4/4GB)
Now when I press a button nothing happens. Can’t see what could be wrong.
this my config:

{
    module: 'MMM-Buttons',
    config: {
        buttons: [
            {
                pin: 23,
                name: "page changes",
                longPress: {
                    notification: "PAGE_DECREMENT",
                    payload: {action: ""}
                },
                shortPress: {
                    notification: "PAGE_INCREMENT",
                    payload: {action: ""}
                },
            },
            {
                pin: 24,
                name: "monitor_control",
                longPress: {
                    notification: "REMOTE_ACTION",
                    payload: {action: "MONITOROFF"}
                },
                shortPress: {
                    notification: "REMOTE_ACTION",
                    payload: {action: "MONITORON"}
                },
            },
            {
                pin: 25,
                name: "power",
                longPress: {
                    title: "Power off",
                    message: "Keep pressed for 3 seconds to shut down",
                    imageFA: "power-off",
                    notification: "REMOTE_ACTION",
                    payload: {action: "SHUTDOWN"}
                },
		 shortPress: {
                    title: "test page up",
                    notification: "PAGE_INCREMENT",   // as test
                    payload: {action: "1"}            // as test
                },
            },
        ]
    }
},

@johans - they are connected to ground or must the common be connected to the 3.3V pin?

@johans

I just started doing exactly what you are trying to do. I have managed to get MMM-Buttons working with one button, but not getting reliable results.

I first tried MMM-Button and was able to confirm button press worked as was getting a message in the logs saying the button was pressed.

Correct ground and i thought the other needs to be one of the green GPIO, sorry not at home so cant check

@johans I guess you need to use a pulldown resistor to avoid floating GND.
Here is a sketch how to use the pull-down-resistor. I had the MMM-Button module installed in the past, but replaced with a gesture sensor (MMM-GorveGestures)

@fozi - Thanks will check if a resistor does the trick - if not I order a gesture sensor
