MMM-SystemMonitor

[Richard238]

Installed, added to config.js

		{
            module: 'MMM-SystemMonitor',
            position: 'bottom_right',
            config: {
                updateInterval: 60000,
                cpuThermalZone: 0,
                units: config.units,
            }
        },

MM fails to load.
Comment those lines out, MM is OK. What have I missed?

@Richard238 what is the end of the last prior module

[Richard238]

@sdetweil

It’s the currently misbehaving weather forecast:

		{
			module: 'weather',
			position: 'top_right',
			header: 'Weather Forecast for: ',
			config: {
				type: 'forecast',
				location: 'nnnnnnnnn',
				locationID: '11111111',  //ID from https://www.openweathermap.org
				apiKey: 'aaaa444444444444444444'
			}
		},

		//{
            //module: 'MMM-SystemMonitor',
            //position: 'bottom_right',
            //config: {
                //updateInterval: 60000,

[2025-02-02 21:35:32.330] [INFO]  Checking modules structure configuration ... 
[2025-02-02 21:35:32.511] [ERROR] Cannot read properties of undefined (reading 'units') 

Module says:

units: config.units,

And also tried with

units: metric,

Which failed with:

[ERROR] metric is not defined 

config.js towards the beginning says:

units: 'metric',

[sdetweil]

@Richard238 to the right of :

Numbers and true/false do not need quotes
Any thing that has a letter needs quotes

[Richard238]

@sdetweil

I don’t understand, sorry?

[sdetweil]

@Richard238 in config.js all properties are

name : value

The value, to the right of the colon (:)
If a number or tr/false
Does not need quotes

If it contains a letter or symbol
It needs quotes

units : metric
To the right is metric
It has letters, so needs quotes

[Richard238]

@sdetweil

That’s fixed it.

Module in config.js

units: 'config.units'

config.js before modules

was

units: 'metric',

Changed it to

units: "metric",

Quite how Free Memory can be 128% I’ve no idea, that’s for another day.
For now, it’s working. Thank you!

@Richard238 cool. Single or double quotes don’t matter as long as they are matched

Be careful on quotes and copying from the forum

If the quotes are curved, they are word processing style and Javascript doesn’t understand them
" or ’

If they are vertical, they are good

" or  '

I’m new to MM and just been putting together my board over the last week.

I’ve used your module and think it’s great.

One thing I did find is that your default way of grabbing diskspace had the device hard coded.

I made this change to node_helper.js:

async.apply(exec, "df -h /|grep dev|awk '{print $4}'"),

That looked for the root partition and was able to then return the correct value for me.

@mebster5 submit that as a pr
