Hi all,

I made some investigations about the temperature of my PI…

without any cooling - around 52 degrees Celsius
with a heatsink from an old PC stuck with cable ties - around 42 degrees Celsius
with heatsink and a fan, also from my old PC - around 30 degrees Celsius

May be this is interesting for someone who use a PI in a close frame.

@adrian-k here an example how it can look, if you store this HTML

in your modules-folder and display it in your mirror:

@harney I’m plannig to use an old case of a router to build something similar like you did, so there will be also some jokes from my family!
Did you include a speaker at the rear side, or just a fan?

I added a graph about the progress of the CPU-temperture of my RPI3 to my MM via RRDtool:

It looks a little bit nerdy, but the temperature is a nerdy hardware characteristic. OK, it is not so beautiful like grafana…but much easier to use.
Therefor, it needs only a few steps to realize it:

sudo apt-get install rrdtool

will install it.
Only one time create the database in the terminal session:

rrdtool create cputemp.rrd --step 300 DS:temp:GAUGE:600:-20:90 RRA:AVERAGE:0.5:12:24 RRA:AVERAGE:0.5:288:31

Add two tasks to crontab:

2-57/5 * * * * rrdtool update cputemp.rrd N:$(vcgencmd measure_temp | cut -c "6-9")

moves every 5 minutes the temperature to the database established above.

0 * * * * rrdtool graph /home/pi/MagicMirror/modules/cputemp.gif --start -24h --title "CPU-Temperatur" --vertical-label "Grad Celsius" --disable-rrdtool-tag DEF:cputemperatur=cputemp.rrd:temp:AVERAGE LINE1:cputemperatur#ff0000:"CPU-Temperatur" ;

generates once in an hour a graph which will be displayed later. If you like, you can adjust the map legend (“CPU-Temperatur” and “Grad Celsius”) with descriptions in your language.

Now create a file named cputemp.html in the modules-folder of your MM:

<HTML>
<HEAD>
<TITLE>CPU Temperatur</TITLE>
</HEAD>
<body bgcolor=#000000>
	<img src="cputemp.gif"/>
</body>
</HTML>

and use MMM-SmartWebDisplay in your config.js to show it:

//#################################################################################
		{
			disabled: false,
			module: 'MMM-SmartWebDisplay',
			position: 'top_center',
			config: {
				logDebug: false,
				height: "180",
				width:"500",
				updateInterval: 0,
				NextURLInterval: 0,
				displayLastUpdate: false,
				url: ["/modules/cputemp.html"],
				}
		},
//#################################################################################

Based on these steps, some more modifications of the appearance are possible. Please use your favorite search-engine for more.

@natebrown enter crontab -e at the prompt and insert the data garbieflux mentioned.
If you struggle with the syntax, you can use several internet-pages to define the rules:
https://crontab-generator.org/
or
https://crontab.guru/ for exapmle

I use
@reboot sudo sh -c ‘echo none > /sys/class/leds/led0/trigger’
@reboot sudo sh -c ‘echo 0 > /sys/class/leds/led0/brightness’
@reboot sudo sh -c ‘echo none > /sys/class/leds/led1/trigger’
@reboot sudo sh -c ‘echo 0 > /sys/class/leds/led1/brightness’
to turn off the LEDs at my RPI 3+

Btw, an # at the beginning of the line marks it as a comment.

Or use a time-switch to turn on and off the whole construction.

Hi,
I looked today for a module for the Tour de France…and found none.
But I was able to integrate a kind of screenshot from a webside with the total results.
I would like to share it with you.
Create a file with the following content, name it tdf.html and store it in the MagicMirror-modules folder (sorry, I was not able to add it as a html-source, only as a picture, but it is standard-html and only some lines:-)):

Download and install the MMM-SmartWebDisplay if not done before and add the following part to your config.js

		{
			module: 'MMM-SmartWebDisplay',
			position: 'top_center',	
			config: {
				logDebug: false, 
				height: "1000px", 
				width:"1000px", 
                         	updateInterval: 15, 
             	                NextURLInterval: 0, 
				displayLastUpdate: false, 
            	                url: ["/modules/tdf.html"], 
				}
		},

leads to this screen:
