weatherforecast showing only two days.

erik.voznak

Hey Guys,

After latest update of MagicMirror (v2.12.0) module weatherforecast is showing only two day forecast no matter what I configure in “maxNumberOfDays” option.

Can you please help me? I tried to search for any errors in logs regarding this module or api response, but I wasn`t lucky.
Below is my config for this module and screenshot to show that it shows only two days.

{
module: “weatherforecast”,
position: “top_right”,
header: “Predpoveď počasia”,
config: {
lang: “sk”,
location: “Bratislava”,
locationID: “3060972”, //ID from http://bulk.openweathermap.org/sample/city.list.json.gz; unzip the gz file and find your city
appid: “6ba6364f776c4927bf2145c8582e8c3c”,
maxNumberOfDays: “7”,
colored: “true”,
fade: “false”,
fadePoint: “1”,
showRainAmount: “true”,
scale: “true”,
}
},

@erik-voznak have you tried

maxNumberOfDays: 7

needs to be a number instead of a string.
fadePoint as well.
You need to be careful with the format of the values.
Look into the readme what format is expected.

@erik-voznak said in weatherforecast showing only two days.:

you shouldn’t have posted it but I checked your appid and is wrong or not valid {code 401}

Had the same issue after the update.
The problem is, that the weatherforecast first checks the paid version of the API to get full day forecasts (https://api.openweathermap.org/data/2.5/forecast/daily?id=xxx&cnt=7&units=metric&lang=de&APPID=xxx)

This results in a 401 for me because I’m using a free API token.

Next the weatherforecast module falls back using the 5 day / 3 hour Forecast API by using the same cnt value (https://api.openweathermap.org/data/2.5/forecast?id=xxx&cnt=7&units=metric&lang=de&APPID=xxx). Here the value 7 for cnt returns 7 entries, that’s why there is only a two day forecast.

I’ll try to write a fix.
In the meantime as a quick fix you can change line 297 of weatherforecast.js from:

params += "&cnt=" + (this.config.maxNumberOfDays < 1 || this.config.maxNumberOfDays > 17 ? 7 : this.config.maxNumberOfDays);

to

params += "&cnt=" + (this.config.maxNumberOfDays < 1 || this.config.maxNumberOfDays > 5 ? 40 : this.config.maxNumberOfDays * 8);

Remeber the fallback API provides only a 5 day forecast, that’s why maxNumberOfDays is limited to 5.

@hango, yeah I know I shouldn`t but I am using free API so… but anyway I will change appid.

@oemel09, Many thanks man, your fix helped and finally it is working as intended.

This fix worked for me too, so thanks very much.

Also, showRainAmount: “false” does not work - i still see mm rain forecast against each day.

This is all a little disappointing as up until the recent upgrade, ‘weatherforecast’ was working perfectly.

And BTW, in trying to resolve the problem with ‘weatherforecast’, before coming to this thread, I also tried the ‘weather’ module, the replacement for ‘currentweather’ and ‘weatherforecast’. I couldn’t get that to work in ‘forecast’ mode, only in ‘current’ mode. The module just displays ‘Loading…’.

Ho-hum…
