Help with MMM-ModuleSchedule to turn off monitor

  • Hi All,

    I want to use MMM-ModuleSchedule and MMM-Remote switch off the monitor. I know remote is working as I can connect to it using my phone but when I get an error message when I start to use the schedule which is just a cut and paste job. Not sure what I am doing wrong but below is the code for the two modules along with the error message when starting MM.

    Thanks for any help.


            module: 'MMM-ModuleScheduler',
            config: {
                notification_schedule: [
                    // TURN THE MONITOR/SCREEN ON AT 07:30 EVERY DAY
                    {notification: 'REMOTE_ACTION', schedule: '30 6 * * *', payload: {action: "MONITORON"}},
                    // TURN THE MONITOR/SCREEN OFF AT 22:30 EVERY DAY
                    {notification: 'REMOTE_ACTION', schedule: '30 8 * * *', payload: {action: "MONITOROFF"}},
                    {notification: 'REMOTE_ACTION', schedule: '00 16 * * *', payload: {action: "MONITORON"}},
    				{notification: 'REMOTE_ACTION', schedule: '00 21 * * *', payload: {action: "MONITOROFF"}},
                    {notification: 'REMOTE_ACTION', schedule: '0 2 * * SUN', payload: {action: "RESTART"}}
            module: 'MMM-Remote-Control',
            // uncomment the following line to show the URL of the remote control on the mirror
            // position: 'top_right',
            // you can hide this module afterwards from the remote control itself
            config: {
                apiKey: ''

    This is the error message:

  • @mlm198 cd to that module folder, and do

    npm install -save cron

    Looks like the module package.json doesn’t list that drpendency

  • @sdetweil thanks for the response and forgive my lack of knowledge but which of the folders listed?


  • go to you ‘magicmirror’ folder, then to modules, and then to the MMM-Remote-Control folder and run ‘npm install’, I think you forgot that.
