Weather service not working anymore?

[balatis]

Use this for sunrise/sunset. Object data type must be set to text/string.

Code:

123456

astro = data.forecast.forecastday[ 1 ].astro grp.write('32/4/1', astro.sunrise) grp.write('32/4/2', astro.sunset) grp.write('32/4/3', astro.moonrise) grp.write('32/4/4', astro.moonset)

You can also use built-in rscalc function for this: https://forum.logicmachine.net/showthread.php?tid=1010

Hi
I'm doing it like that

Code:

require('socket.http') forecast = {} function parsetag(parser, tag, attributes)  if tag == 'time' then    table.insert(forecast, {})  elseif tag == 'symbol' then    forecast[ #forecast ].symbol = attributes.name  elseif tag == 'precipitation' then    forecast[ #forecast ].precipitation = attributes.value  elseif tag == 'windDirection' then    forecast[ #forecast ].wind_direction = attributes.code  elseif tag == 'windSpeed' then    forecast[ #forecast ].wind_speed = attributes.mps  elseif tag == 'temperature' then    forecast[ #forecast ].temperature = attributes.value  elseif tag == 'pressure' then    forecast[ #forecast ].pressure = attributes.value  end end url = 'http://www.yr.no/place/United_Kingdom/England/Farnborough/varsel.xml' data, err = socket.http.request(url) if data then  require('lxp').new({    StartElement = parsetag  }):parse(data)  grp.update('Weather precipitation', tonumber(forecast[1].precipitation))  grp.update('Weather symbol', forecast[1].symbol)  grp.update('Weather windDirection', forecast[1].wind_direction)  grp.update('Weather windSpeed', tonumber(forecast[1].wind_speed))  grp.update('Weather temperature', tonumber(forecast[1].temperature))  grp.update('Weather pressure', tonumber(forecast[1].pressure))  --log(forecast)   else  alert('Fetch failed: ' .. tostring(err)) end

Looks great, but i still dont understand where to put the GA in. Sorry for the low lewel of knowlegde.

[Erwin van der Zwart]

Hi,

Is already in the script but this sample uses the object names instead of GA’s.

Change in all lines grp.update('Weather precipitation', ... to grp.update('1/1/1', ... etcetera

Of course you didnt. I may have to blame some saturday night fever or something. Changed it back to how it was supposed to be and then it is working..

But if i use any city in the world script is working. But using any Norwegian city i get that the service is stopped. And script not working. Kinda strange since it is an norwegian site.

Anyone got this working in Norway.

Looks like they don't provide XML in this format anymore. I suggest using Apixu instead, you just have to register for a free account: https://forum.logicmachine.net/showthrea...8#pid11518

[Daniel]

Hi
It works fine only you need to use correct location for example for Oslo it is https://www.yr.no/place/Norway/Oslo/Oslo...varsel.xml
Just go here https://www.yr.no/ search for your City and copy location from this url and paste in to XML url.

I made (partially found) a quick and dirty integration with met.no for a weather service a while back. Met.no is the same instance as YR.no.

Maybe someone can use (and improve, its messy) it. This version only collects the temperature and sends it to 1/1/0. Temperature is correct for the locations I have tried it. Loads of other information available in the output file. Also, you need to specify the correct longitude and latitude on the LM/SL for it to work.

Code:

12345678910111213141516171819202122232425262728293031323334353637

Hello. I use weather script for https://www.yr.no/ . And next required for visualization- how much and what values can take variable forecast[1].symbol ( cloudy, rain...) to assign icons for each state?

[admin]

All symbols are listed here: https://hjelp.yr.no/hc/en-us/articles/20...bols-on-Yr
Full icon name is also supplied in XML:

Code:

1

forecast[ #forecast ].icon_name = attributes.var

Hi,

How to get moon data from apixu script?

moon_phase
moon_illumination

BR Even Sundgot.

[Erwin van der Zwart]

Hi,

Just log the table ‘current’ to see what index fields are available and if the data exists use it like the rest, could be something like current.moon_phase but you will know when looking at the data table.

BR,

Erwin

Hi Erwin,

Thanks for the reply, when i log astro i get this reply:

* table:
[moonset]
 * string: 07:42 AM
[sunrise]
 * string: 06:28 AM
[moonrise]
 * string: 10:39 PM
[sunset]
 * string: 06:58 PM

So it seems like there is no data for moon, but the strange thing is that in the Api manual the moon data is described.

BR Even Sundgot.

Apixu free tier does not provide astronomy data. Moon phase calculation is relatively simple. Here's a formula that gives number of days since new moon cycle:

Code:

1234567891011121314151617181920

local date = os.date('*t') local y, m, d = date.year, date.month, date.day if m < 3 then   y = y - 1   m = m + 12 end local a = math.floor(y / 100) local b = math.floor(a / 4) local c = 2 - a + b local e = math.floor(365.25 * (y + 4716)) local f = math.floor(30.6001 * (m + 1)) local jd = c + d + e + f - 1524.5   local dn = jd - 2451549.5 local nm = dn / 29.53 local dc = (nm % 1) * 29.53 log(dc)

Thanks Admin,

Is there a way to get what phase the moon is in right now?

BR Even Sundgot.

[admin]

Use this:

Code:

123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354

local date = os.date('*t') local y, m, d = date.year, date.month, date.day if m < 3 then   y = y - 1   m = m + 12 end local a = math.floor(y / 100) local b = math.floor(a / 4) local c = 2 - a + b local e = math.floor(365.25 * (y + 4716)) local f = math.floor(30.6001 * (m + 1)) local jd = c + d + e + f - 1524.5 local dn = jd - 2451550.1 local nm = dn / 29.530588853 local dc = (nm % 1) * 29.530588853 local ph if dc < 1.84566 then   ph = 0 elseif dc < 5.53699 then   ph = 1 elseif dc < 9.22831 then   ph = 2 elseif dc < 12.91963 then   ph = 3 elseif dc < 16.61096 then   ph = 4 elseif dc < 20.30228 then   ph = 5 elseif dc < 23.99361 then   ph = 6 elseif dc < 27.68493 then   ph = 7 else   ph = 0 end local phases = {   [0] = 'new moon',   [1] = 'evening crescent',   [2] = 'first quarter',   [3] = 'waxing gibbous',   [4] = 'full moon',   [5] = 'waning gibbous',   [6] = 'last quarter',   [7] = 'morning crescent', } text = phases[ ph ] log(ph, text)

You can use ph number as object value and set custom values according to phases table (0..7).

Hi,

Here is a small contribution from me and others (mostly others in fact). 
The script fetches the weather forecast from Yr.no

I've put together some of the previous scripts, and removedsome functions and correct the error handling. 
I am not a big fan of using functions only once. I find it makes the code less readable because you have to jump all over the place when you read it. 

There is also a description at the beginning of the code explaining how to use it.

Cheers.
Michel

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.
