One solution would be modifying the source. It is not so difficult. Just a few lines are needed for that. Then make a PR and wait to be accepted by the module owner.

The real issue is… The module owner - @gfischershaw seems not to manage this module any more. As an original developer of this module, I feel some responsibility. Maybe I should get back from this unmaintained situation. (I’m not sure what to do yet.)

Second solution would be the conjunction with MMM-NotificationTrigger module. It could chain/translate one notification to other notifications. So you can relay TOUCH_IDLE_TRIGGERED to {SHOW_HIDDEN_PAGE, 'screenSaver'} . See that. Or I think there would be some equivalent modules somewhere.

from Pages’s github

SHOW_HIDDEN_PAGE	String	MMM-pages will switch to the provided hidden page name.

from Touch’s github

// will send a TOUCH_IDLE_TRIGGERED notification
onIdle: "TOUCH_IDLE_TRIGGERED",

I’ve successfully got the Touch module to send a notification based on the onIdle timer. I just don’t know how to specify my Page’s screensaver page along with the payload.

"SHOW_HIDDEN_PAGE", 'screenSaver'

my code for each module

{
        module: 'MMM-pages',
	disabled: false,
    classes: 'default everyone',
        config: {
                modules:
                    [[ "MMM-DateOnly", "clock2" ],
			[ "MMM-OpenWeatherMapForecast", "clock" ],
            [ "calendar", "clock" ],
			[ "clock", "MMM-Wallpaper" ]
			],
                fixed: [ "weather", "MMM-page-indicator", "MMM-SimpleLogo" ],
                hiddenPages: {
                    "screenSaver": [ "MMM-Wallpaper", "MMM-FlipClock" ],
                    "admin": [ "MMM-ShowMeSystemStatsModule", "MMM-AnOnScreenMenuModule" ],
                },
        }
    },

{
    module: "MMM-Touch",
    position: "top_bar",
    disabled: false,
    config: {
    debug: false,
    useDisplay: false,
	autoMode: false,
    defaultMode: "default",

  threshold: {
    idle_ms: 3000, // Idle time (in milliseconds) after which the defined "onIdle" notification / callback function should be triggered
  },
  onIdle: ("SHOW_HIDDEN_PAGE", 'screenSaver'),

        gestureCommands: {
            default: {
                TAP_1: (commander) => {
                    commander.sendNotification("USER_PRESENCE", true);
                },
                PRESS_1: (commander) => {
                    commander.sendNotification("USER_PRESENCE", true);
                },
                TAP_2: (commander) => {
                    commander.sendNotification("LOAD_NEXT_WALLPAPER", true);
                },

                "SWIPE_UP_1" : (commander) => {
                  let clock = commander.getModule('MMM-OpenWeatherMapForecast')
                  clock.show()
                },
                "SWIPE_DOWN_1" : (commander) => {
                  let clock = commander.getModule('MMM-OpenWeatherMapForecast')
                  clock.hide()
                },

                SWIPE_UP_2: (commander) => {
                    commander.sendNotification("SHOW_HIDDEN_PAGE", "screenSaver");
                },
                SWIPE_DOWN_2: (commander) => {
                    commander.sendNotification("LEAVE_HIDDEN_PAGE");
                },

                SWIPE_LEFT_1: (commander) => {
                    commander.sendNotification("PAGE_INCREMENT", null);
                },
                SWIPE_RIGHT_1: (commander) => {
                    commander.sendNotification("PAGE_DECREMENT", null);
                }
            },
        }
    }
},

"SWIPE_UP_1" : (commander) => {
  let clock = commander.getModule('clock')
  clock.hide()
},

I think @MMRIZE answered

  gestureCommands: {
    "default": {
      "SWIPE_UP_1" : (commander) => {
        commander.getModules().forEach((m) => {m.show()})
      },
      "SWIPE_DOWN_1" : (commander) => {
        commander.getModules().forEach((m) => {m.hide()})
      }
    }
  },

Swiping up with one finger would reveal modules.
Swiping down with one finger would hide modules.
But in the real world, some modules are protected with lock string from hiding/showing,

i’d like to create a swipe up and swipe down to hide and unhide a module. thank you.

but if there is a fatal error, it probably cant write the logs

either there is a module missing
a syntax error
or some fatal problem in the front end (mmm-touch.js)

how do you start MM

npm start
or pm2?

if npm start , keyboard alt-spacebar, n to minimize
if pm2,
pm2 logs --lines=100

if still nothing obvious, open the developers window, ctrl-shoft-i on the mirror keyboard,
select the tab labeled console and scroll up… errors are usually in red text

The onNotification function seems important to me. if I change to page two for example, the gestures can be defined in another way compared to page one.
My problem is, when I add the code and restart my mirror everthing stays black. usually if there is a bug in the config.js an error is mentioned. but in this case it just stays black.
If I uncomment the code everthing is fine again.
This even happens when i use the example code. Knowing that it wont do anything on my magic mirror, it should start anyway.
So i am wondering if there is a bug or if i am doing something wrong?
Do you use the module?

I see https://github.com/gfischershaw/MMM-Touch

and what is the question about onNotification?

when a notification is received, you can examine and optionally respond (somehow)
