@randomnoise Great! Thank you, now it works as intended again :)

There seems to be an update whitch changes the functionality from showing all the trains of one station to showing a specific connection. For me it didn’t work any more, so i created a new module with the new Search API if you are interrested: MMM-swisstransport

To update electron enter your MagicMirror folder any execute npm install :)

I suggest you open a topic on the raspberry pi forum as well… Maybe somebody can elaborate on where we have to look for a solution.
