Calendar module: connecting to radicale server

kimpenhaus · Dec 28, 2018, 1:10 PM

Hi guys,

I am fairly new to MM - so a warm hello to everyone :waving_hand: - and just set up my raspberry pi 3 recently. No fancy stuff, just the default modules (clock, weather, forecast and calendar) and MMM-BackgroundSlideshow.

Our family calendar is running on a radicale docker container which I’d like to connect. The calendar itself doesn’t require any auth to receive and is through the browser by the url downloadable. But the same url in the config doesn’t seem to work. I also have OSX, iOS and Android running against the radicale container with no problems.

Also interesting even though I changed the fetchInterval to 600.000 the log still says that the fetcher is created with an interval of 300.000.

My config is as follows:

{
    module: "calendar",
    header: "Kalender",
    position: "top_left",
    fetchInterval: 600000,
    maximumEntries: 5,
    config: {
        calendars: [
            {
                symbol: "calendar-check-o ",
                dateFormat: "dd.MM.yyyy",
                url: "https://url-to-ical-sevrer/",
            }
        ]
    }
},

Logfile shows:

Does anyone has this kind of setup already running? Any advice would be appreciated :)

So I got two steps further:

First the easy fix for the fetchInterval. Those config parameter needs to go into the config section of course … doh :smiling_face_with_smiling_eyes:

    module: "calendar",
    header: "Kalender",
    position: "top_left",
    config: {
            fetchInterval: 600000,
            maximumEntries: 5,
            calendars: [
            {
                symbol: "calendar-check-o ",
                dateFormat: "dd.MM.yyyy",
                url: "https://url-to-ical-sevrer/",
            }
        ]
    }
},

The problem, why the calendar couldn’t be fetched, is TLS related. I used the debug.js file which I found in the modules folder to trace down the error:

Error "unable to verify the first certificate"

The provided certificate is signed by let's encrypt - as a workaround I currently used: process.env.NODE_TLS_REJECT_UNAUTHORIZED = 0; I know that this is not the recommended way.

I am running node version 9.11.2 - maybe someone has a working fix for that problem?
