      I’m running a RPi4 with the latest MM release and using MMM-Screen-Powersave-Notification and MMM-GPIO-Notifications along with a motion sensor.

       {                   
      	module: 'MMM-Screen-Powersave-Notification',
      	config: {                 
              delay: 60
      	}
          },
      
      
          { 
      	module: 'MMM-GPIO-Notifications',
      	config: {
      	    '4': {
      		    gpio_state: 1,
      		    gpio_debounce: 0,
                  delay: 30000,
      		    notifications: [
      		        { 
      				    notification: 'SCREEN_ON', 
      		            payload: { 'forced': false }
      		        },
                      {
      
                      }
      		    ]
      	    }
      	}
          },
      

      I had this setup on a Dell monitor and it worked perfectly.

      I just installed a new monitor - a Lenovo Thinkvision P32p-20

      After starting the sensor works as it’s supposed to, waking the monitor when someone passes by and sleeping after 60 seconds of inactivity.

      But after a while, the monitor does not wake from sleep. The MM instance is running fine (I can look at the dispaly from a remote browser).

      The monitor is in powersave mode (amber LED)

      The only way to wake the monitor is to touch a button on the monitor’s control panel.

      The monitor has no configuration options for powersave or sleep.

      Any suggestions on how to fix this?

        @mvrlogins I had a display like that, if no input, it would turn off, even if I was hiding modules.

        I had to make a change to one of my modules to wake up mm for 1 second every 14 minutes to keep it from going into shutdown

        the monitor doc says moving a mouse (if it were visible) should wake up the monitor

          May I ask how you did that?

          Thanks

            @mvrlogins I had to add code to my module, that started a 14 minute timer on entering sleep mode. if motion happened before the timer expired the timer was stopped.

            if the timer expired, I set a variable and then started the wake up routine.
            during the wakeup, if the variable was set is started a second timer for 1 second

            when that second timer expired I cleared the variable and then started the sleep routine again…

            repeat as needed.

            causes a short flash every 14 minutes, but mostly this happens at night, when u are sleeping anyhow.

            energy star compliance requires power off (or low power suspend mode) after 15 minutes of no use.
