@sdetweil I subscribed to onecall and I just tested this morning and I still have the same “loading” thing, in my config.js I put the following things:

{
module: "MMM-OneCallWeather",
     position: "top_right", // This can be any of the regions.
     // Best results in bottom_bar region due to horizontal default layout and icon sizes.
     config: {
       // See 'Configuration options' for more information.
       latitude: "46.561180", // Longitude from https://www.latlong.net/
       longitude: "-1.782440", // Longitude from https://www.latlong.net/ - is West + is East of London
       apikey: "MY NEW API KEY V3.0" // openweathermap.org API key.
     }
   },

in MMM-OneCallWeather.js I have this:
letdata;

Module.register("MMM-OneCallWeather", {
   // Default module config.
   defaults: {
     latitude: true,
     longitude: true,
     apikey: "",
     apiVersion: "3.0",
     units: config.units,
     layout: "vertical", // default
     showRainAmount: false,
     showWind: true,
     showWindDirection: true,
     showFeelsLike: true,
     tempUnits: "c",
     windunits: "mph",
     useBeaufortInCurrent: false,

     initialLoadDelay: 2500, // 2.5 seconds delay. This delay is used to keep the OpenWeather API happy.
     updateInterval: 10 * 60 * 1000, // every 10 minutes
     animationSpeed: 1000,
     updateFadeSpeed: 500,
     lang:config.language,
     language: config.language,
     requestDelay: 0,

I haven’t touched anything else, can you help me please?

@sdetweil Yes but it’s thanks to people like you that there is still communication without banking intermediary to build projects… I would therefore stay with my version 2.5 which is free while waiting for a developer to find a solution:- ) what bothers me is that the weather forecast with pretty icons etc. there are some on smartphones, cars, television, internet etc. and all this is free, as soon as you want to do something different you have to PAY :-(

@sdetweil Thank you for your answer and you are right everything is charged today, fortunately there are still sites and people like you to share for FREE what they know

@sdetweil Yes I went to this page, but then they ask you for your bank card!!!

@sdetweil on my weather module I have an api key 2.5, I don’t know if that’s it but I have the impression that the weather data is wrong. Do you know of a weather module for the MM with current and forecast that would be graphically nice and free? because if to have version 3.0 you have to pay that doesn’t interest me, thank you for your help

@sdetweil So it pays?

@sdetweil when I connect to an internet page it gives me this, so I think it’s active, I entered lat, long and api key

@sdetweil In detail he says this:
(apiVersion The OpenWeatherMap API version to use. Change it to “2.5” if you have an old apikey

Default value: 3.0)
I understood that if we had an old version then we had to change this parameter but I may have misinterpreted

@sdetweil Hello Sam, I still need your help, I saw KristjanESPERANTO’s module: MMM-OneCallWeather which I really like, so I installed this module I copied his example from js.config which I have completed with my elements longitude, latitude apy key, I tested my api key on the internet in version 2.5 and it works, so I changed the version in MMM-OneCallWeather.js, as Kristjan explains in the github, and when I restart the MM it notifies loading and nothing happens, I tried to understand, but I’m stuck, so I call a specialist :-)

@sdetweil I found, you have to set this setting to “0”, otherwise it reloads every 30 seconds

NextURLInterval: 0,
