      It works!

      after testing some things PM2 didn’t work anymore, so i recovered from a backup, installed the drivers for the DS18B20 again, copied the scripts back, restarted and it works.

      Don’t know why and how, but it does :smile:

      Solved!

        This sounds awesome…

        Is this downloadable from github?

          No, it’s not available on GitHub. But with the hints from @MichMich it was pretty easy to realize.

          To load the drivers for the DS18B20 I followed these instructions https://www.kompf.de/weather/pionewiremini.html

          To get the DS18B20 working with node.js I installed this https://www.npmjs.com/package/ds18x20

          And finaly I edited the scripts of the systemtemperature-module and it works.

          Step-by-Step

          • Add this line to your /boot/config.txt
          dtoverlay=w1-gpio,gpiopin=4,pullup=on
          
          • Add to your /etc/modules following and reboot the Pi
          w1-gpio pullup=1 
          w1-therm
          
          • Note the ID of your sensor (go to /sys/bus/w1/devices and list the files, the ID should look something like this 28-04163746c8ff
          • Got to /MagicMirror/modules and create a folder named MMM-Temperature
          • Create a file named MMM-Temperature.js and copy the code from my post for this script
          • Create a file named node_helper.js and copy the code from my post and change the ID of my sensor to yours (it’s in line 16)
          • Register this module in your /MagicMirror/config/config.js
          • Restart your MM and you are done :)

          Hope I could help. Let me know if it works.

            Mate. That’s just awesome.

            Few worry spots but sure I can make that happen.

            I made sure to order the same temp module so hopefully I shouldn’t have trouble.

            Thanks mate. Awesome.

            May have questions tho so will yell out of i do when eBay comes thru lol

            Thanks again
