@sdetweil Thanks!
The option UpdateInterval is optional.

Anyway. Shorter than 5 min makes no sense because the database on tankerkoenig updates every 4 min.

@sdetweil modifiying is another method :winking_face:
I think the problem was the number of request at a time. There list up to 9 Request at the same Timestamp.

EDIT: Error found by myself!
The value for UpdateInterval must set to 900000 //15min
RTFM!

Thanks for your time!

@sdetweil i never publish my own API_KEY :winking_face:
As i mentioned before, the url (with the right key in it) works perfekt in a Browser.

@sdetweil see Attached Picture

@sdetweil Thanks for testing.
Yes, the url works perfekt in a Browser - but not in MMM-Fuel.
Best of all: it works perfekt and show up in MM.
Maybe it runs too often and was rejected by tankerkoenig.de. The Logfile from tankerkoenig API shows up the massive requests --i can’t append the logfile–

UpdateInterval: 15 says 15 Minutes - right?

@sdetweil sorry i can`t fully reply. AKISMET SPAM :-(

Can`t connect to tankerkoenig.

Hello, this is my first try to use MMM-Fuel. Dependencies already installed with npm install
I get this error every seconds in the MM-Logfile:

0|MagicMirror | { FetchError: request to https://creativecommons.tankerkoenig.de/json/list.php?lat=47.551609&lng=10.251099&rad=3&type=all&apikey=API_KEY&sort=dist failed, reason: connect ECONNREFUSED 188.68.35.147:443

The URL works just fine in a Browser and shows up the Gas-Stations near to me.

My config file:

{
			module: "MMM-Fuel",
			disabled: false,
			position: "top_left",
			config: {
				provider: "tankerkoenig",
				api_key: "API_KEY",
				lat: 47.123456,
				lng: 10.123456,
				types: ["e5"],
				sortBy: "e5",
				radius: 3,
				max: 3,
				updateInterval: 15,
			}
		},

Thanks for any hint.
