An other option is working with variables in your custom CSS-file and making all of your modules the same width. Changing the width is than done only on one place in your custom CSS-file.

Try this in your custom.css and ad all your modules to it.

/* Vars */
:root {
	/* Width for all modules */
	--mod-width	: 310px;			/* only px no % */
}

/* Make all modules same width */ 
.clock {
	width	: var(--mod-width);
}
.calendar {
	width	: var(--mod-width);
}

I do the same with colors I use in my custom CSS-file.

@Mykle1 said in MMM-WorldTides, no output on screen:

However, tell me what info you are looking for regarding the tides. Do you simply want the current day’s high and low tides with the times they occur?

I’am living near the coast and often go for a walk along the beach. It’s handy to now when it’s high or low tides, especially if I want to photograph. But I have patience, do not hurry, just worry that I do not get it working.

@Mykle1
I would highly appreciate it.

@yawns
Thanks for your time.
When I can help (test) give a call .

@yawns and others,
Just installed your module WorldTides.

On screen I only get the info that the WorldTides data is loading … But even after 2 minutes it is still loading. What am I doing wrong?
I can’t find my error, grrr !!!

This is my part of the config.sys

{
	module		: 'MMM-WorldTides',
	position 	: 'top_right',
	header		: 'Getijden',
	config		: {
		longitude	: '52.212',
		latitude	: '4.399',
		appid		: '************************************'
	}
},

When I do a call in my browser I get a result from the server.
The call I make :
http://www.worldtides.info/api?extremes&lat=52.212&lon=4.399&lenght=2592000000&key=************************************

The result I get, within a second;

I even tried the longitude and latitude as a number, but that is not a solution either.
longitude : 52.212, (without ‘’)

@Johannes said in Problems with MagicMirror modules, Calendar, weather-forecast, newsfeed:

First problem, I use MMM-MyCalendar witch has more options for config and is working great. Try this one. And there are errors in your config.sys

{
	module: "calendar",
	position: "top_left",
	config: {
		calendars: [
			{
				url: "url google-Calendar",
				fetchInterval: 60000,
				timeFormat: "relative",
				displaySymbol: false
			},
			{
				url: "url 2nd google-Calendar",
				fetchInterval: 60000,
				timeFormat: "relative",
				displaySymbol: false
			}
		]
	}
},

There are problems with Weather forecast, there is work in progress. Link to News Item.

For your last problem there are some errors in your config.sys. Number and false/true never use “…” or ‘…’

{
  module: "newsfeed",
	position: "bottom_left",
	config: {
		feeds: [
			{
				title: "Nachrichten",
				url: "http://www.tagesschau.de/xml/rss2"
			}
		],
		showPublishDate: false,
		showSourceTitle: true,
		showDescription: true,
		updateInterval: 15000
	}
},

@cowboysdude
There is no excuse in being late !

@Mykle1
Now you need to make a timer module !
_ Leaving at hh:mm to wedding of … (or other event)
_ You still have hh:mm:ss before leaving (time leaving -/- actual time)

How about that !!!

@Nystro0m
Looks to me that there is two times the same code in the js-file ecxept for the language settings. So @cowboysdude has to look into this.

@Akzariel
The RPI 3 has Wifi onboard, so you don’t need a Wifi adapter !

For other components take a look at adafruits.com or the pihut.com, there are a lot off add on components.
