Weather service not working anymore?

Hi to all,

I tried Michell's code (with either his or my city code) and I am always getting an alert:

Fetch failed: error:1409442E:lib(20):func(148):reason(1070)

and the script stops. I tried to find any error description in yr.no but no luck.

Any ideas?
Thank you in advance.

Did you put https in the url? 
The script works only with http.

Regards.
Michel.

Since there's no response from Yahoo we suggest using https://apixu.com instead. You will have to create a free account and make sure that your script does not fetch data too quickly (not less than once in 5 minutes).

Here's a short example, change key variable to your API key, location variable to required location in textual form. This example fetches current weather condition and forecast for today and tomorrow. Fields can be found in apixu documentation: https://www.apixu.com/doc/forecast.aspx (day Element).

Code:

require('json')
https = require('ssl.https')
escape = require('socket.url').escape

key = 'my_api_key'
location = 'my location name'

url = 'https://api.apixu.com/v1/forecast.json?key=%s&q=%s&days=2'
url = string.format(url, key, escape(location))

res = https.request(url)

data = json.pdecode(res)
if type(data) ~= 'table' then
  alert('failed to load weather data')
  return
end

if data.error then
  log('error', data.error)
  return
end

current = data.current
today = data.forecast.forecastday[ 1 ].day
tomorrow = data.forecast.forecastday[ 2 ].day

-- log(current, today, tomorrow)

-- temperature in C
grp.write('32/1/1', current.temp_c)
-- "feels like" temperature in C
grp.write('32/1/2', current.feelslike_c)
-- humidity as percentage
grp.write('32/1/3', current.humidity)
-- wind speed in kilometers per hour
grp.write('32/1/4', current.wind_kph)
-- uv index
grp.write('32/1/5', current.uv)
-- weather condition text
grp.write('32/1/6', current.condition.text)
-- pressure in millibars
grp.write('32/1/7', current.pressure_mb)
-- precipitation amount in millimeters
grp.write('32/1/8', current.precip_mm)

-- minimum temperature in celsius for the day
grp.write('32/2/1', today.mintemp_c)
-- maximum temperature in celsius for the day
grp.write('32/2/2', today.maxtemp_c)
-- average temperature in celsius for the day
grp.write('32/2/3', today.avgtemp_c)
-- average humidity as percentage
grp.write('32/2/4', today.avghumidity)
-- maximum wind speed in kilometers per hour
grp.write('32/2/5', today.maxwind_kph)
-- uv index
grp.write('32/2/6', today.uv)
-- weather condition text
grp.write('32/2/7', today.condition.text)
-- total precipitation in millimeters
grp.write('32/2/8', today.totalprecip_mm)

-- minimum temperature in celsius for the day
grp.write('32/3/1', tomorrow.mintemp_c)
-- maximum temperature in celsius for the day
grp.write('32/3/2', tomorrow.maxtemp_c)
-- average temperature in celsius for the day
grp.write('32/3/3', tomorrow.avgtemp_c)
-- average humidity as percentage
grp.write('32/3/4', tomorrow.avghumidity)
-- maximum wind speed in kilometers per hour
grp.write('32/3/5', tomorrow.maxwind_kph)
-- uv index
grp.write('32/3/6', tomorrow.uv)
-- weather condition text
grp.write('32/3/7', tomorrow.condition.text)
-- total precipitation in millimeters
grp.write('32/3/8', tomorrow.totalprecip_mm)

Now i get always the alert failed to load weather data.
What im doing wrong ?
The same script has worked before.
Is there something changed in the apixu ?

Works for me, try logging server response.

Replace:

Code:

res = https.request(url)

With:

Code:

res, code, hdrs, stat = https.request(url)
log(res, code, hdrs, stat)

And post what you get in Logs tab.

This is what i get :

Which firmware version are you running? Can you send your Apixu key via PM?

This is probably due to older FW, as a work-around you can use HTTP request instead:

Code:

require('json')
http = require('socket.http')
escape = require('socket.url').escape

key = 'my_api_key'
location = 'my location name'

url = 'http://api.apixu.com/v1/forecast.json?key=%s&q=%s&days=2'
url = string.format(url, key, escape(location))

res = http.request(url)

data = json.pdecode(res)
...

I am all new to the LM and are on a steep learning path. I've been struggling to get the yr.no xml API script to work for my Yr location. However, after further inspections and testing I found out that the xml from norwegian locations have a subtle difference compared to other location. I could get all others to work, but not for any norwegian places.

For norwegian places you get an additional text section as below:

  <forecast>
    <text>
      <location name="Oslo">
        <time from="2019-12-06" to="2019-12-06">
          <title>Obs! Note!</title>
          <body>Tekstvarsel-tjenesten er nedlagt. The text forecast service is suspended</body>
        </time>
      </location>
    </text>

Because of this the first index to values must be 2 instead of 1. That eventually made things work for me. I don't know why nobody has mentioned this before. Maybe this is a recent change? Or is it me missing something here...?

Hi,
how correctly attach weather icons to visualization?
As example I have group with icon number or name - 250 byte string - 03n, and I have icon 03n.png. How better show it at visualization?

Thank you in advance,

Alex

admin,

thank you, now will check and add to my icon's control

This is probably due to older FW, as a work-around you can use HTTP request instead:

Code:

require('json')
http = require('socket.http')
escape = require('socket.url').escape

key = 'my_api_key'
location = 'my location name'

url = 'http://api.apixu.com/v1/forecast.json?key=%s&q=%s&days=2'
url = string.format(url, key, escape(location))

res = http.request(url)

data = json.pdecode(res)
...

Weather service is working, but from different url 

url = 'http://api.weatherstack.com/current?access_key=%s&query=%s'

will return table data.current like this

* table:
["cloudcover"]
  * number: 59
["visibility"]
  * number: 10
["observation_time"]
  * string: 12:24 PM
["uv_index"]
  * number: 5
["wind_dir"]
  * string: NNW
["humidity"]
  * number: 60
["weather_descriptions"]
  * table:
  [1]
    * string: Cloudy
["wind_speed"]
  * number: 21
["weather_code"]
  * number: 119
["is_day"]
  * string: yes
["pressure"]
  * number: 1017
["precip"]
  * number: 0.1
["weather_icons"]
  * table:
  [1]
    * string: https://assets.weatherstack.com/images/w..._cloud.png
["feelslike"]
  * number: 10
["temperature"]
  * number: 12
["wind_degree"]
  * number: 327

Is there any kind of change in the weather script?

I see that the application loads it well without errors and even updates the data ... but it does not send the correct values for the season of the year in which we are ...

[admin]

Which one are you using?

Which one are you using?

Hello admin, this is my script.

Code:

require('json')
http = require('socket.http')
escape = require('socket.url').escape

key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
location = 'xxxx'

url = 'http://api.weatherstack.com/current?access_key=%s&query=%s'
url = string.format(url, key, escape(location))

res = http.request(url)

data = json.pdecode(res)
if type(data) ~= 'table' then
  alert('no se pudieron cargar los datos del clima')
  return
end

if data.error then
  log('error', data.error)
  return
end

current = data.current

-- temperature
grp.write('32/1/1', current.temperature)
-- "feels like" temperature
grp.write('32/1/2', current.feelslike)
-- humidity as percentage
grp.write('32/1/3', current.humidity)
-- wind speed in kilometers per hour
grp.write('32/1/4', current.wind_speed)
-- uv index
grp.write('32/1/5', current.uv_index)
-- weather condition text
grp.write('32/1/6', current.weather_descriptions[1])
-- pressure
grp.write('32/1/7', current.pressure)
-- precipitation amount
grp.write('32/1/8', current.precip)

[admin]

Maybe the location is incorrect? You can use latitude, longitude format to get a more precise results. Try logging JSON data, maybe it will provide some useful information.

Hi Admin , Didn't understand how to use your script ? Could you please give me some instructions about it .

[admin]

Which script exactly? There are many examples that use data from different services.

[mkaymak]

Code:

require('json')
https = require('ssl.https')
escape = require('socket.url').escape

key = 'my_api_key'
location = 'my location name'

url = 'https://api.apixu.com/v1/forecast.json?key=%s&q=%s&days=2'
url = string.format(url, key, escape(location))

res = https.request(url)

data = json.pdecode(res)
if type(data) ~= 'table' then
  alert('failed to load weather data')
  return
end

if data.error then
  log('error', data.error)
  return
end

current = data.current
today = data.forecast.forecastday[ 1 ].day
