I also had this problem of flickering when I used the fake dtoverlay=vc4-fkms-v3d . Now that I am using the “original” OpenGL driver it is solved for me.

@sdetweil wow I was not aware of all old events also being sent and parsed… from 5+ years ago. That’s a lot of entries… (more than 1500 only for my main calendar)
I sent the log via eMail to you.

adding an address: "0.0.0.0",did it, I can see the black page of MM in my browser… thanks a lot for your help. Now I’m even more waiting for my mirror and screen to arrive…

I use crontab and added
@reboot tvservice -o to deactivate hdmi output on start. You can activate it on demand (as I do) or maybe after 60 seconds

@sdetweil

/MagicMirror $ grep version package.json
        "version": "2.26.0",

@sdetweil what do you mean with latest mm version? I did git pull && npm install, so I should have the latest…

I have a very similiar problem. I use two calendar modules, one with dates from the local waste pickup service and another one with multiple google calendars. The waste calendar works fine (so nothing with the module), but google gives errors. I copied out two of the google-calendars:

[03.01.2024 11:05.10.477] [ERROR] Calendar Error. Could not fetch calendar:  https://calendar.google.com/calendar/ical/XXXXX/basic.ics RangeError: Invalid time value

I don’t know what invalid time value means, maybe someone can help

@Matuki
To be honest I have no idea how to do this.

But I found the time to dig a little into the module I used before and found some problems. With some tweaks I could get it running and also uploaded it to github, just in case anyone was using this before and also misses it. You can find it in https://github.com/AnduriI/MMM-forecast-io

@Matuki
in the javascript console I see

ReferenceError: WeatherProvider is not defined
[...]
TypeError: this.weatherProvider is undefined
[...]
Uncaught (in promise) TypeError: this.weatherProvider is undefined

I suppose thats the problem, but I don’t know how to handle. I added it exactly as in your example config. Also in your config the lat/lon are stated to be string with “” - maybe you could update this.

@Matuki
Hey,
can you help me with the config of your modules please? I tried to add this (with lat, lon and api):

		{
			module: "MMM-WeatherChartD3",
			position: "bottom_right",
			config: {
				lat: "",
				lon: "",
				apiKey: "",
				weatherProvider: "openweathermap",
				weatherEndpoint: "/onecall",
				initialLoadDelay: 1000,
				type: "full",
				lang: "de"
			}
		},

but I only get an header with undefined and a line

@thobach
Hello,
I would be great to have a screenshot on the github page as a preview and some config options listed. I just installed it to try out, but I personally don’t like having multiple graphs stacked. Can they be fused together?

@lavolp3
Thank you for the offer to upload your code to github, I realy appreciate that.
I already had a look at FlatPepsi before, but I didn’t liked to graphics that much. It looked to much cluttered with all those small numbers. I liked the clean astetics of rklueber with only one red and one blue - you can get it in one glance. Or is that configurable? Maybe line thickness and hide numbers…
Also that shade below the curve helped to identify them very easy

Hey there,

I used to have the module MMM-forecast-io forked by rklueber with a realy nice graph for the upcoming day. (https://github.com/rklueber/MMM-forecast-io)
This was based on the old datasource DarkSky and showed only “loading…” since it’s shutdown. I thought about migrating the data source to OpenWeatherMap, but in the meantime I reinstalled my MM and now the module doesn’t show anything. Probably something with dependencies…
Is there an activ module which can show something similiar? Or is there an kind of easy way to get the old module running and migrate?

Thank you,
Anduril
