MMM-CalDAV

@MMRIZE
Yes, that’s what I thought too.
But I checked it again, and it’s the same URL my Synology ist showing for the calendar.
“Http://localip:5000/caldav/”

Maybe some settings on my synology are the problem?! I already checked the port, it’s open.

@Tiller what is localip?

[Tiller]

@sdetweil
The local IP of my synology.
Something like 192.168.0.x

[sdetweil]

@Tiller ok… just checking…

just fyi IP addresses 192.168.x.y NEVER cross the internet… they are ‘unroutable’ on purpose
172. and 10. are also like that

if you share that I cannot reach it…

mine network is 192.168.2.x

Hello and a happy new year to you all.

I checked the URL, tried different versions. Used the tried the same URL I use on my smartphone (the url is working), but always get the same error.

I don’t know what to do or try.
I checked the firewall and port settings on my synology, but still the same error.

Do you have any other ideas?

[sdetweil]

@Tiller thanks… just needed caldav and calendar

[sdetweil]

@Tiller said in MMM-CalDAV:

http://localhost:8080/CALDAV/SYNOLOGY_Calendar.ics

if you open that on browser someplace it works??

[Tiller]

@sdetweil

No, it still doesn’t work. I checked the path of the .ics, which should be stored in /MagicMirror/MMM-CalDav/service/
as a hidden file, but I can only find the placeholder.txt

Tillmann

[sdetweil]

@Tiller i do not know… sounds like the MMM-CalDav module didn’t mnake the conversion for some reason

[Tiller]

@sdetweil

Hello,
it’s working now, but without the MMM-CalDAV module.
I checked the url I’m using on my phone and just added it to the standard calendar module and added a “.ics” at the end of the url. Now it’s working. I tried this before and it wasn’t working.
Now it is.
Thanks for your help and support.

Best
Tillmann

[sdetweil]

@Tiller awesome!! thanks for the feedback

Hello,
Please Can you help me and Sorry for my bad English.

The following errors are clear thats the result from the First ERROR.

What im doing Wrong or thinking false?

[sdetweil]

@MrPringless did you run
npm install
In the module folder after the git clone?

git clone …
cd MMM-CalDAV
npm install

[MrPringless]

@sdetweil Thanks for your reply.
It’s a bit crazy. I completely reinstalled everything two days ago using copy and paste from the module page.
Then I copied the .env file from the old installation to the new installation.
Could this be because I copied the .env file from a backup into the directory after the reinstallation?
Thanks for the feedback, because I’d like to learn from my mistakes.

[sdetweil]

@MrPringless I do not know the inner workings of the module.

typically
module not found
means npm install for the module was not done or the package.json for the module didn’t list the library dependency. MMRIZE is very good on that point, so I don’t the second is the reason…

but thanks for the nudge… my backup/restore scripts will save/restore extra files discovered in a modules folder… but files with leading dot are hidden by convention… so I will have to check that

I would not have picked up the .env file… fixed… thx
