Weather Info from API
#1
Hello, 
Please, I hope you could help me in my issue
However, I was trying to get the weather infomation from apixu.com and write them on the KNX bus.
I just followed the exemple on the openrb.com this one (https://openrb.com/featch-weather-forecast-from-apixu), I only changed the key variable as it's mentioned in the exemple.

This is the scheduled script that I used.
Code:
require('json')
https = require('ssl.https')
escape = require('socket.url').escape

key = '737ad147e5be532e3d78995a68f4a160'
location = 'Norway'

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)


No data was found on those groupe addresses, 
Or if you could give me any other solution, I only wants to write 1 on the KNX bus if there's a snow tomorrow, the place is Bergen in Norway

Very grateful in advance

yr.no provides free detailed forecast API.
This example will check if there will be snow in the next day. You only need to adjust your location (latitude/longitude) and the status object address. There might be some limits on how often the API can be accessed so create a scheduled script that runs every 3 hours or so.
Code:
latitude = 60.3894
longitude = 5.33
status = '1/1/1'

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

args = 'lat=' .. latitude .. '&lon=' .. longitude
url = 'https://api.met.no/weatherapi/locationforecast/2.0/compact?' .. args
mac = 0
io.readfile('/sys/class/net/eth0/address'):gsub('%x%x', function(v)
  mac = mac * 256 + tonumber(v, 16)
end)
http.USERAGENT = 'LM ' .. mac

res, err = http.request(url)
data = json.pdecode(res)

if type(data) == 'table' then
  date = os.date('*t')
  date.day = date.day + 1
  time = os.time(date)
  timestamp = os.date('%Y-%m-%d', time)

  snow = false

  for i, entry in ipairs(data.properties.timeseries) do
    if entry.time:sub(1, #timestamp) == timestamp then

      next1h = entry.data.next_1_hours
      code = ''

      if type(next1h) == 'table' and type(next1h.summary) == 'table' then
        code = next1h.summary.symbol_code or ''
      end

      if code:find('snow') then
        snow = true
        break
      end
    end
  end

  grp.checkwrite(status, snow)
end

Hi Admin,

May I ask for a little bit of help also?
Do you experience problems with the setup explained here: https://openrb.com/featch-weather-forecast-from-apixu
Have and account and key but I get the following message:

The free tier in weatherstack does not provide forecast data, only current conditions. Consider using yr.no instead. We will publish an updated integration script for yr.no next week.

Thank you for your replay!
I've been using YR until recently but it stopped. Looking forward to your YR script update Smile

Hi,

may be some news about new yr.no weather script? Looks like one of the best free weather informers now..

Hi, super job is done!. Will test it in nearest time.

Some ideas for improvements/additional possibilities:

1. If weather info is needed for place where device is located - possible not to show coordinates directly in script but take them from system:

require('uci')

latitude = uci.get('genohm-scada.core.latitude')
latitude = tonumber(latitude) or 0

longitude = uci.get('genohm-scada.core.longitude')
longitude = tonumber(longitude) or 0

If 0 - no coordinates - should be entered than..;

2. Would be great if we can show group addresses for weather conditions in the beginning of script, because these groups will be created later in this script (addresses showed natively, not by names). I see it was planned to do so, but was commented.. For me groups 33/1/XX are used, For test I will manually change them in script;

3. In my existing weather script I use weather condition icons. So condition is taken from informer, than condition's icon is showed at visu...
May be ''symbol code'' info from yr.no we can add to script and use with icons?

4. how often we can start this script? Once a day? Some informers not allowed very often requests and can block them, or allows for additional payment..

BR,

Alex

I have found out that, there was wrong name for object of maximum wind speed

was
Code:
status_max_wind_speed_today = grp.create({ datatype = dt.float16, address = '33/1/15', name = 'today_press_max',})

should be
Code:
status_max_wind_speed_today = grp.create({ datatype = dt.float16, address = '33/1/15', name = 'today_wind_max',})

The updated version of weather script.
1.) Added possibility to read coordinates (latitude and longitude) from system.
2.) Changed data types of objects:
        a.) for humidity dt.scale
        b.) for uv_index dt.uint8
        c.) for pressure dt.uint16

Code:
-- Please comment objects which you are not using, comment also grp.write() at the bottom of script


--[[
-- You can set latitude and longitude in "Date time" option
-- go to LogicMachine->Utilities->Date and time

require('uci')

latitude = uci.get('genohm-scada.core.latitude') -- read latitude from system
latitude = tonumber(latitude) or 0

longitude = uci.get('genohm-scada.core.longitude') -- read longitude from system
longitude = tonumber(longitude) or 0

if(latitude == 0 and longitude == 0) then -- if cooridinates were not set in the system
  latitude = 51.5072 -- London
  longitude = 0.1276 -- London
end

4. How often we can start this script?
You can run the script every four hours, should work fine.

Thank you for the script RomansP!

Have tested, but I get no data coming to addresses 33/1/*. All stay at 0.
Although I receive a link with data when I log (url) at line 272.

Is it still working with you?

Hi, Mrinj!

Yes it is still working for me. Can you attach your script, so I will try to figure out what could gone wrong.

Added check for http.request , so there will be a log if something gone wrong.

Have tested, but I get no data coming to addresses 33/1/*. All stay at 0.
Although I receive a link with data when I log (url) at line 272.

Is it still working with you?

Great script, 

Thank you for sharing it.

As sad earlier, from your script I only change the addresses to 53/1/* from your script cause my 33/*/* once are busy Smile
Script is attached.

Thanks!

RomansPHi, Mrinj!

Yes it is still working for me. Can you attach your script, so I will try to figure out what could gone wrong.

The updated version for script.

Added check for http.request , so there will be a log if something gone wrong.

Code:
res, code = http.request(url)

if res and code == 200 then
  data = json.pdecode(res)
else
  log('request error', res, code)
end


Code:
-- Please comment objects which you are not using, comment also grp.write() at the bottom of script

-- go to LogicMachine->Utilities->Date and time

longitude = uci.get('genohm-scada.core.longitude') -- read longitude from system
