org-weather for openweathermap.org

org-weather for openweathermap.org

[Chris Raschl]

Hi everybody,

recently I wanted to add a weather forecast to my org-agenda. I found
org-google-weather, but this package is obsolete since 2012, because the
API is not available any more. So I wrote my own version which is backed
by the openweathermap.org API.

I implemented the minimal usecase which works for me, if somebody else
dares to use it, its available here:

https://github.com/kautsig/org-weather

Regards,
Chris

Hi,

Nothing particular to say except that it is nice, and working well!

Thank you for this!

Nice, thank you, never made org-google-weather, but this works
out-of-the-box:

`--------------------------------------------------------------------------

- why not use (round ...) for the temperature data, 10-17°C would be
  more than accurate enough?

- why not include city/country info in the weather string? I added 

  * Weather
    :PROPERTIES:
    :CATEGORY: City
    :END:
  %%(org-weather)

  to get the above, but it would be much better to take the return
  values for city/country and include them in the weather string, to
  make sure one did not mess up the configuration and gets the weather
  from another place than expected.

- maybe make the whole thing a bit customizable by adding a few
  defcustoms, so the user can decide which info he wants to print in the
  agenda

  the return string looks like this, there are many options:

Hi Thorsten,
first of all, thanks for your suggestions, I really appreciate it.

I added this. Additionally I removed the temperature unit being
displayed twice, this was unnecessary and looks much nicer in the format
you suggested.

Also thought about this, but I think I will go with the method which was
also used in org-google-weather. It looks like:

* Weather
%%(org-google-weather "New York")

This is much simpler for me, as I'm not so familiar with lisp and the
org-mode api. But I'll have to change the data structure for caching the
data a bit, so it might take a while.

I improved result processing a little bit and added a formatting string
(org-weather-format). You can now also add different temperature fields,
as well as humidity, pressure and wind speed.

and for your improvements

  ,--------------------------------------------------------------
  | City:     Weather: broken clouds, 11-22°C, 1028hpa, 75%, 3m/s
  `--------------------------------------------------------------

this fits my needs perfectly (living in a city right now). 

PS
Coming from a coastal area, I know that high tide, low tide, water temp
as well as moon phase are also very important for "fishermen" and
friends (just like wind speed and direction). 

This would probably make a nice accompagnient library for yours,
displaying something like this below the line above in the agenda:

,----------------------------------------------------------------------
| Coast: high: 06:43/19:25 low: 13:12/02:30 water: 18°C moon: ++++ wind: SE
`----------------------------------------------------------------------

with moon: ++++ meaning 4/4 visible (full-moon), moon: ++ meaning 2/4
visible (half-moon), moon: - meaning 0/4 visible (no moon), and wind: SE
meaning South-East.

Maybe someday if I need it again and have time ;-)

Not sure though if this data (except the moon phase) is as universally
and easily available as the data you display .... Sunset and rise would
be interesting too of course.

I've written the `weather-metno-el' package.  Which uses the weather data from 
met.no (CC licensed).  It supports showing weather data in the org-agenda as 
well.

You can get sunrise and sunset by doing something like in an Agenda file:

* Weather.

Lat N 51 57.931
Long W 03 33.191

#+CATEGORY: Day/Year
&%%(diary-day-of-year)

Thanks, had to use this to make it work:

#+CATEGORY: Citiy
%%(diary-sunrise-sunset)


 City:      6:32...... Sunrise (CEST), sunset 11:16pm (CEST)

But somehow lat/long are right, but time is 2h off ... I'm GMT+2 (CEST) here. 
Where is the time adjusted for diary entries?

When it rains it pours (sorry ...)

I've tried both packages and they are very nice. Thanks a lot!

of the units  in specified in the org-weather-unit variable

The Emacs manual has the information:

[I don't have an org-weather-unit variable, so I presume you mean
org-weather-temperature-unit.]

Yes, one needs to change the API URL as well to get different units:

,----
| (defvar org-weather-api-url "http://api.openweathermap.org/data/2.5/forecast/daily?q=%s&mode=json&units=metric&cnt=7")
`----

AFAICT, they provide "metric", "imperial" and "internal" (don't know
what the last one means).

org-weather.el itself does not do any units conversions.

just trying this package.  Also really nice!  Thanks for sharing.

I have a few questions/comments/feature requests, though:

1. Documentation of available targets.
   I wanted to include the wind speed.  Looking at the schema [fn:1] I
   tried 'windspeed' which did not work.  It took some time until I
   found the 'weather-metno--data' variable, which revealed that it
   is 'windSpeed' instead.
   Some table with all the available measurements would be handy.
   | parameter | representation | unit   | example   |
   |-----------+----------------+--------+-----------|
   | windSpeed | name           | string | Svak vind |
2. How can I get a textual representation of the symbol?
   I would like to get (additionally to the symbol) get a textual
   description (like 'partly cloudy').  I did not see an obvious way
   how to get that.
3. Two or three entries per day
   How can I have two (night/day) or better three
   (night/morning/afternoon) entries for each day?  I would like these
   to sum user-defined times.  E.g. night: 20-08, morning: 08-13 and
   afternoon 13:20.  Is that (easily) possible?
4. The org agenda entry does not point to anything.
   It would be cool (I think) if the org agenda entry pointed to a
   *Weather* buffer with detailed information from weather-metno-forecast
5. The Readme for the manual installation could remind the user to put
     (require 'weather-metno)
     (require 'org-weather-metno)
   in the .emacs
6. The documentation of 'org-weather-metno-format' points to
   'weather-query-format' which should
   probably be 'weather-metno-query-format'

Andreas
