Your config.js should have:
{
module: 'MMM-EMonitor',
position: 'top_left',
config: {
security_key: 'XXXXXXXXXXXXXXX' //your security key
}
}
This just displays everything in a large table. You may want to modify the for loop to not display data when the wattage is 0, that should get rid of a bunch of rows.
