UNSOLVED Monitor not awaking from sleep

[mvrlogins]

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.
