Hi Simon,
create a local html-file at the modules folder with the following content:
Name it as you like (mychart.html for example) and add the path to MMM-SmartWebDisplay instead of the URL you entered before:
url: [“/modules/mychart.html”],
Play around with the red-marked values…the exact data depends on the browser in use.
This way is much easier than to adjust it directly in MMM-SmartWebDisplay.
Greetings

@stefan723 May be, a so called “Step Down” resp. “Step Up”-resistor is needed. The PI has built-in Step Down/Up functionality.
The issue may arise due to interferencies from other parts around the sensor and the PI. First follow the idea of @Stefan723 and try to use short cables.
Use Google to search for “Step Down/Up and Raspberry PI”.
But I’m a programmer…not an electrician:-)
@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.

@sdetweil yes, I tried it but the parameter (margin/width/high etc.) drives me crazy…it was much easier for me to create a local html. And it is not time-critical. updating every 24 hours will be enough.
Thomas
@adrian-k here an example how it can look, if you store this HTML
in your modules-folder and display it in your mirror:
Didn’t I said, I’m not an electrician?
It is not a step-down/up … it is called Pull-Up, resp Pull-Down.
Please see here for detailed (german) explanation: https://www.elektronik-kompendium.de/sites/raspberry-pi/2006051.htm
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.

Hi all,
I made some investigations about the temperature of my PI…
@Bungle68 I have good experiences with MMM-EasyPix.
You have to store your logo(s) in the subfolder “pix” of the module.
Hi, is it possibel to send a noticication with x-y-coordinates as payload witch end-up as a mouseclick at the screen?
Thank you in advance.
@Tom_LabHIdouille I’m not familiar with compliments, but can’t you create a locale html-file at the modules folder with the link to the picture you prefer and add the name of the html at all the compliments-module(s).
The benefit would be only to change the locale file and all the compliments-modules should show your picture.
@Egnos You can use RDDTOOL, I described it here: https://forum.magicmirror.builders/topic/16575/cpu-temperature-as-a-graph-with-rrdtool?_=1666781012238
But instead of creating an extra html, you can use the output directly with MMM-EasyPix:
//#################################################################################
{
disabled: false,
module: "MMM-EasyPix",
position: "top_center",
config: {
picName: "cputemp.gif",
maxWidth: "100%",
// sounds: ["1.mp3", "me2.mp3"],
updateInterval: 600000,
animationSpeed: 1000,
}
},
//#################################################################################
@sdetweil said in [Default clock] Incorrect week number:
I see the code set moment from the language set in config.js
DE
@sdetweil it is set to Berlin = CEST
and my clock-config-entry is like this:
//#################################################################################
{
disabled: false,
module: "clock",
position: "top_right",
config: {
// The config property is optional.
// See "Configuration options" for more information.
showWeek : true,
showSunTimes : true,
showMoonTimes : true,
lat : 50.658821,
lon : 7.193084,
}
},
//#################################################################################
@sdetweil That is a good answer:-)
I’m from Germany and my mirror shows 42, the answer to all questions.
@sdetweil I know, but to have a first sense of achievement he will see something different than “LOADING”
