@sdetweil thx!

@sdetweil Dear Sam,
thanks for this information.
Can you please enlighten me?
I can read what you wrote and I got a light idea - but didn’t understand …

I definitely have used your install script.
what is @electron and
what correlation is between node-libgpiod and @electron ? and what will this

../../node_modules/.bin/electron-rebuild

do?

Sorry for these questions - I would like to understand, what happens.

If this is “neccessary” I will try to automate this for others with a postinstall script.
Thanks for your effort!
warmest regards,
Ralf

@_V_ as you might have overseen you can not only check several conditions (as Sam (@sdetweil ) suggested) - separated by else or not but you can make several changes to the same event at one check.

e.g.:

eventTransformer: (ev) => {
  if (ev.title.search("Restmüll & Papier & Gelber Sack") !== -1) {ev.isFullday = [true], ev.title = "Alle Tonnen", ev.symbol = [ "fa-regular fa-trash-can" ], ev.color = "fuchsia"}
  if (ev.title.search("Therapie") !== -1) { ev.title = "Sitzung", ev.symbol = [ "fa-solid fa-mug-hot" ], ev.color = "Forestgreen"}
return ev
   			  }, // end Eventtransformer 

In the above example you can see

• the modification of the color (as you already had identified,
• the change of the kind of event (from “scheduled” to “Fullday-Event”)
• the assignment of a different symbol (with font-awesome-symbols: double check their web-page, keep in mind that only the “STANDARD” (non-payed) versions will be shown in Magic Mirror) and
• the change of the title of the event.

Hope this helps.
Good luck!
Ralf

You could try Karsten‘s suggestion…
Replace your configs gpioCommand with the suggested one and check what happens…
As I had assumed in my earlier post it‘s may related more to gpio than to HDMI …
