Openweather api

Openweather api
Hello
I am implementing the Openweather API in a wiser for KNX.
For now the current time I get it perfectly and I can save the data in virtual objects.
This is the script.

Code:

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

key = 'xxxxxxxxxxxxxxxxxxx'
location = 'city'

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

res = http.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
log(current)

-- temperature
grp.write('32/2/10', current.temperature)

-- Dirección del viento
grp.write('32/2/11', current.wind_dir)

-- Velocidad del viento
grp.write('32/2/12', current.wind_speed)

-- Humedad
grp.write('32/2/13', current.humidity)

-- Presión
grp.write('32/2/14', current.pressure)

-- Descripción
grp.write('32/2/15', current.weather_descriptions)

-- ¿Día/Noche?
grp.write('32/2/16',current.is_day)

-- ¿Índice UV?
if current.uv_index <2  then
 
grp.write('32/2/17','Bajo')
 
elseif current.uv_index == 3  then
 
  grp.write('32/2/17','Normal')
 
  elseif current.uv_index == 4  then
 
  grp.write('32/2/17','Normal')
 
  elseif current.uv_index == 5  then
 
  grp.write('32/2/17','Normal')
 
  elseif current.uv_index == 6  then
 
  grp.write('32/2/17','Alto')
 
  elseif current.uv_index == 7  then
 
  grp.write('32/2/17','Alto')
 
  elseif current.uv_index == 8  then
 
  grp.write('32/2/17','Muy Alto')
 
  elseif current.uv_index == 9  then
 
  grp.write('32/2/17','Muy Alto')
 
  elseif current.uv_index == 10  then
 
  grp.write('32/2/17','Muy Alto')
 
  elseif current.uv_index >11  then
 
  grp.write('32/2/17','Extremadamente Alto')

end

This is the result on the current variable

Code:

weather 20.07.2020 13:00:38
* table:
["cloudcover"]
  * number: 0
["visibility"]
  * number: 10
["observation_time"]
  * string: 10:53 AM
["uv_index"]
  * number: 7
["wind_dir"]
  * string: SE
["humidity"]
  * number: 59
["weather_descriptions"]
  * table:
   [1]
    * string: Sunny
["wind_speed"]
  * number: 17
["weather_code"]
  * number: 113
["is_day"]
  * string: yes
["pressure"]
  * number: 1014
["precip"]
  * number: 0
["weather_icons"]
  * table:
   [1]
    * string: https://assets.weatherstack.com/images/wsymbols01_png_64/wsymbol_0001_sunny.png
["feelslike"]
  * number: 32
["temperature"]
  * number: 30
["wind_degree"]
  * number: 130

The problem is with weather_descriptions, I see that it is a table and I assign it to an object like the others, if I log it, the contents of the table appear to me, the object is updated but it does not show anything. It is defined as the 14 byte DPT ASCII string. How do I get that data from that table inside another table and assign it to the object?

Also I would like to know if it is possible to use in a conditional loop if a range of numbers, for example that it only be executed if it is between 8 and 10. Since I don't know how to do it I have evaluated each value independently at the end of the script. I do this so that the UV index is displayed in text instead of a number.
a greeting

Thank you very much
