Hi @hubobel
Thanks for your contribution. I’ll give them a try!
Allow me to make a side note: Although there are a bunch of people speaking german (including me), it would be great to see your posts in english so everyone could benefit from those :)

Thanks!

@sdetweil Thanks for your response! I’ve restarted the whole host system (Raspberry Pi 4) several times and the message is gone.
Regarding your hint: I’ve actually tried it but hadnt any luck in identifying the correct DOM node. Also searching in the DOM tree for the word didn’t return any item.

Nevermind: Issue is gone since restarting the whole system :)

It’s not documented in Github README, but you find the needed config in the implementation here

So…try the following and add the windUnits property.

{
            module: "MMM-OneCallWeather",
            position: "top_right",
            header: "xxxxxx, // OPDATERET HEADER
            config: {
                latitude: "xxxxxx", // OPDATERET LATITUDE
                longitude: "xxxxx", // OPDATERET LONGITUDE
                apikey: "xxxxxxx",
                iconset: "4a",
                iconsetFormat: "png",
                units: "metric", // Styrer at vindhastighed er i m/s
                fade: false,
                windUnits: "ms" //ADD THIS PROPERTY
            }
        }

Version 1.0.0

• First version adding the overall functioanilties.

@KristjanESPERANTO I set up a fresh MagicMirror instance and checked the https://github.com/MarcLandis/MMM-Buttons repository. As a result I get the same issue:

[2025-06-09 22:57:35.709] [ERROR] Whoops! There was an uncaught exception...

}

…Yesterday evening I tried to fix the issue of not beingable to control the MagicMirror using some buttons. Digged into the original module, asked help of ChatGPT, debugged some functions and as a result I have a running version for Bookworm.
I’ll try to put this in a Github Repo - will update this thread as soon as I did :)

@sdetweil You’ve said that I only need to change some settings in the rasp-config. Do you have any additional information what needs to be changed?

@KristjanESPERANTO Argh…I didn’t see that :-/ Nevermind…at least I’ve learned something about the Module…

@rkorell Thanks for publishing your great module. I already use it and hell yeah - it’s great :)
I was also able to make the needed modification to my “Buttons”-module using the node-libgpiod package. Main reason why it was not working was the missing postinstall script.

Thanks and “schöne Grüße” :)
