see this error on startup

[04.10.2023 07:59.52.457] [ERROR] ReferenceError: HTMLElement is not defined

Where did you meet this error? In backend log? Or console? Or validator?

[eouia]

If you get that message from a Validator(or lint or any DOM Parser), that is not my fault. HTMLElement is a standard native object of javascript in all browser, but some programmatic parser might not be able to handle it. https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement

Anyway, I can add a fallback routine for it in the next update.

const popoverSupported = (typeof HTMLElement !== 'undefined') ? HTMLElement.prototype.hasOwnProperty('popover') : false

this is just out of Electron in MM 2.25, no special code..

the config..

     {

  position: "bottom_bar",

  title: "",
  config: {
    mode: "month",
    //instanceId: "basicCalendar",

    firstDayOfWeek: 1,
    calendarSet: [], // ['us_holiday', 'abfall', 'mytest'],
  }
},
{
    module: 'MMM-Remote-Control',
    // uncomment the following line to show the URL of the remote control on the mirror
    // position: 'bottom_left',
    // you can hide this module afterwards from the remote control itself

MMM-Remote-Control tries to load(require) module file in its node_helper directly.

https://github.com/Jopyth/MMM-Remote-Control/blob/fb20bd483540ebb6eef0c8495cecd807d5dd1e0e/node_helper.js#L314C17-L314C48

Of course, it will fail because HTMLElement is not supported in NodeJS. Should I support the loading module in the NodeJS environment? (Maybe yes. Anyway, I'll add the code above in the next update)

By the way, that kind of approach of MMM-Remote-Control is the easiest way, but I think it would be better to use improved JS Parser instead of loading module directly.
