@sdetweil Thanks, Sam. I don’t use MMM-CalDav. But it has occurred to me that there may be some corruption in my calendar data (heaven knows how many years ago I created these entries) so I’m going to test by deleting a couple of yearly events and recreate them to see if that fixes the problem.

@sdetweil

Thanks for your response. Below is the event from my calendar data. The result on the screen shows this event occurring on Monday (03/23/2026) when, as you can see the next occurrence is not until 12/23/2026.

I have a very out-of-the-box installation of the default calendar module on my mirror. But the mirror’s calendar shows that my brother’s birthday is this coming Monday, which is March 23. However, my iCal (the one referenced in my config) correctly indicates my brother’s birthday is December 23. This seems to occur for all my yearly recurring events.

Anyone noticed this before? I’ve been running my mirror for a couple years now and I think this defect has been there for at least a year. I’ve just been too busy to look into it until now

Thanks in advance for any advice.

@sdetweil Thanks, sam. That’s what I figured. I’ll post here when I figure out what I screwed up.

@CDT It’s obviously been a long time since I checked this post. This tip was very helpful. I was using the wrong vehicle_ID and have changed it. I’m still getting the “Loading…” message. Based on your experience though, I feel like I must have a problem in my config and I’m going to play with it some more today and see if I can straighten it out.

The first error message I see in the console log (actually it’s written to stdout) is an UnhandledPromiseRejectionWarning with a Response Error: 404 Not Found. I’m considering just reinstalling the module in case I’ve edited something trying to troubleshoot and left out a comma or introduced bad line-ending with a funky editor or something.

I will post here if I resolve the issue.

I have coded the following but only get message “Loading …” in the assigned area. Any tips or tricks to getting this to work?

           {
                    module: "MMM-Tesla",
                    position: "bottom_left",
                    config: {
                            email: "REDACTED",
                            password: "REDACTED",
                            client_id: "81527cff06843c8634fdc09e8ac0abefb46...",
                            clent_secret: "c7257eb71a564034f9419ee651c7d0e5...",
                            vehicle_id: "REDACTED",
                            google_api_key: "REDACTED",
                            refreshInterval: 1000 * 60 * 10
                    }

            }
