@ezrael-villan Do you want help on how to create such a “Grade display”, or do you want someone to create it for you?

@zipo13 Just to clarify, what exact file did you edit?

@bhepler Electron is already a premade solution that works great. However using Chromium in Kiosk mode is also a nice and easy solution. And it may solve the issue here.

@Akkor How to open Chromium in kioksmode on startup: https://raspberrypi.stackexchange.com/questions/40631/setting-up-a-kiosk-with-chromium

@grasshopper001 You are in two different scopes. Try to add .bind(this) to your setInterval’s callback.

Also do you see any errors on the browser side?

• Open Chrome and navigate to your MagicMirror’s Webinterface
• Open the Chrome Dev Tools via F12 (on Windows)
• Keep an eye out for anything red in the console
• Optional You can also directly debug your modules code in the dev tools.

@zipo13 Hi and welcome to the MagicMirror Forum!

You can debug it very easily:

Node.js side error:

• Execute pm2 log mm
• This shows you the last 15 lines of the error log, it should give you an idea what may be wrong.

Browser side error:

• Open MagicMirror on your local Browser (Chrome is preferred)
• Open the browsers Debugger, reload the page, it should give you an idea what may be wrong.

You can post the results here for further analysis.

@el-bardo You never know how other module devs use such functions.

Always use the most non-inversive way which would be the custom CSS way.

@el-bardo I would not recogmend to edit the moment.js library. Yes, it may solve your problem but changes to this library will also affect other modules.

In general it is unsave to just adapt a 3rd party library.

@akkor Ok, check the log with the following command: pm2 log mm

On the top you will see the last 15 lines of the error log.

@sollekram Awesome!

@sollekram Ok, did you try to reboot your System yet?
