Problem with Weather forecast

@Aurelsam

You’re not giving a lot of information here. Have you followed the instructions in the README?

[Aurelsam]

Yes i have read everything, i have written the same information as for the current wheater module. But nothing appears…

@Aurelsam

Post your config here

@Mykle1

{

module: “weatherforecast”,
position: “top_right”,

config: {

location: “Saint-Germain-les-Corbeil,France”,

locationID: “2979752”, //ID from http://www.openweathermap.org/help/city_list.txt

appid: “ea0222cc89779d1aXXXXXXXXXXXXXXX”,

maxNumberOfDays: “4”
}

This works for me. Check your appid.

{
	module: "weatherforecast",
	position: "top_right",
	header: "Saint-Germain-les-Corbeil,France",
	config: {
		location: "",
		locationID: "2979752", //ID from http://www.openweathermap.org/help/city_list.txt
		appid: "ea0222cc89779d1aXXXXXXXXXXXXXXX",
		maxNumberOfDays: "4"
	  }

},

@Mykle1
My appid is good because it works with the current weather.
There are no other solutions?
Thx Mykle1

@Aurelsam

Copy and paste my config entry above into your config and DOUBLE CHECK your appid. That entry is working.

EDIT! Working under MM 2.1.1

I have the same problem, even after deep investigations.

I can get current weather calling this :
http://api.openweathermap.org/data/2.5/weather?q=paris&units=metric&APPID=cbbxxxxxxxxxxxxxx

I can get forecast weather with 3h timepoints using
http://api.openweathermap.org/data/2.5/forecast?q=paris&units=metric&APPID=cbbxxxxxxxxxxxxxx

BUT i cannot use daily forecast which is used by MM
http://api.openweathermap.org/data/2.5/forecast/daily?q=paris&units=metric&APPID=cbbxxxxxxxxxxxxxx
it returns : {“cod”:401, “message”: “Invalid API key. Please see http://openweathermap.org/faq#error401 for more info.”}

it appears that daily forecast is not free (anymore ?) regarding openweather website.

Maybe it is a problem related to location ? I see that I actualy live just a few kilometers away from Aurelsam (Saint-Germain-les-Corbeil, France)

[Sp4M]

You can temporarly get around the problem by using 3h steps forecast (2nd link of my previous post) instead of daily, and by adding this to the weatherforecast.js :

in function processWeather,
after line var forecast = data.list[i];

add:

if (forecast.dt_txt.split(" ")[1] != “00:00:00”) continue;

(in config)
maxNumberOfDays parameter now counts timepoints (each 3h) and not days:
maxNumberOfDays: 4 // means 4 forecast points: 0h, 3h, 6h, 9h
maxNumberOfDays: 8 // means 8 timepoints of 3h = 24h = 1 day
maxNumberOfDays: 40 // means 40 timepoints of 3h = 120h = 5 days

You should also remove parameter check in the same script weatherforecast.js, which allow maximum 16 (for 16 days). it should be set to maximum 128 (timepoints) for 16 days.

example:
params += “&cnt=” + (((this.config.maxNumberOfDays < 1) || (this.config.maxNumberOfDays > 128)) ? 40 : this.config.maxNumberOfDays);

I don’t know what to tell you. That entry is working.

Reply to myself! LOL

An oversight on my part. I was testing that in MM 2.1.1 and it WAS working. I just moved to MM 2.1.2 and it does NOT

[plybz18]

Same problem here, for weatherforecast it shows incorrect appid, but same appid is working for current weather.!!!

@Mykle1
So it means that it does not work with the latest version ??
How do you install 2.1.1?

It would appear so. You could try the workaround that @SP4M provided above. I have not tried it.

I did. It works with additionnal calculations if you want to use temperatures - you have to average all temperatures (min and max) from all 3h timepoints of one day.
By the way, it’s less precise than real min and max of the day …

@Mykle1 : how could it be a problem of MM version if openweather does not recognize “forecast/daily” in its url in your opinion ? I should have missed something

Honestly, I don’t know. What I DO know is my appid was being rejected under MM 2.1.2, as reported by the console. Went back to 2.1.1 and the appid is accepted normally. I didn’t investigate any further. Perhaps something in the way the request is being made? I just don’t know.

Well, I just moved to the develop branch, and although the unauthorized appid error is gone, weatherforecast still won’t work, and a new error is reported. The module simply stays on “Loading . . .”

[A Former User]

@Mykle1 I dont know about rhis module, but youd better to see scale field in config. I guess it is missed or invalid.

[A Former User]

@Mykle1 I read dev codes now, scale is not documented yet.(and it has also defined wrongly in defaults.)
Maybe scale:"c" or scale:"f" may work.

[luizcarlosnery]

Same personal problem.
Mm2 does not display the Weatherforecast on the screen.

@luizcarlosnery

There’s a problem with Openweather’s api not accepting certain api keys. In the meantime, you could try another weather module. There are many.
