How do you turn Off/On the monitor if not in use - Be Green

I agree, but the other problem i see with relay, is that you will be able to cut the energy, but once you order to power on, monitor will need human action to press power button :(

The test i did with my LG monitor, was using remote module i did turn Monitor OFF, and my monitor will enter in standby after 2 sec, so i think that i can set the PIR to once detect movement will trigger the monitor to ON, and after X sec, if no movement is detect turn monitor OFF.

I am using a “dual” solution: I do use a PIR sensor together with the MMM-PIR module to switch the monitor to standby via HDMI off. Since the Raspi and the monitor are still consuming energy, I thought about when I do really use my MagicMirror. So I came to the conclusion that I never use and need my MM during night and during my working hours in the week. So I bought a rather cheap clock timer with the capability to program it per day. Every day the MM is switched completely off during night time and every work day during my work time. In order to prevent any potential SD card failure I do use the module MMM-Scheduler to shut down the Raspi well in advance before power is cut. If there is interest I can post the configuration of MMM-Scheduler.

@Steff
The PIR sensor and MMM-PIR Module is on my list as soon as I read up more about them, so I for one would be gratefull if you could post the scheduler config… I want to see if I can mange the set up as smoothly as possible… hence why I want to read up as many posts about it here and in other posts.

Thanks.

@Steff Sure Steff, post the Scheduler configuration.

@mpires
Here is the configuration:

                {
                module: 'MMM-ModuleScheduler',
                config: {
                notification_schedule: [
                                // TURN THE MONITOR/SCREEN OFF AT 8:30 EVERY WEEK DAY
                                {notification: 'REMOTE_ACTION', schedule: '30 8 * * MON-FRI', payload: {action: "SHUTDOWN"}},
                                // TURN THE MONITOR/SCREEN OFF AT 23:30 EVERY DAY
                                {notification: 'REMOTE_ACTION', schedule: '30 23 * * *', payload: {action: "SHUTDOWN"}},
                            ]
                         }
                },

The clock timer is programmed to kill the power supply 15 min later than the shutdown time(s).

@Steff ty Steff, i did order today my PIR.

wizz

I got an solution that i like and hope will work good for me.
I am waiting for my Alexa Dot to arrive and when it dose i will use this to shut down the power to the monitor with the implementation for my Vera edge and a wall plug just telling the Alexa to shut down the monitor and also by command start up the monitor i rely hope that works as for the RPI i let it to be powered on like @broberg mentioned.

So just waiting for the Alexa to drop down in the mail :)

@wizz , I have already done this using an Echo Dot & 5V 4-Channel Wifi Relay module for Arduino LinkNode R4 with couple of coding i made a voice activated power extension plug :) it’s working fine for me !

wizz

@zam Do you want to explain the setup and the coding pleas?
