Wetter mit Open Weather Map API in Python
Ich habe die Aufgabe geteilt:
Ein eigenständiges Modul liest die Daten von openweather und schriebt dies in eine JSON Datei.
Der server liest diese Datei und wandelt Formate um.
Der Client kann jede Sekunde den Status abfragen.
Da sich unser Wetter sich aber (noch nicht) so schnell ändert, reicht es, das Wetter jede viertel Stunde zu holen.
Den Client über crontab starten
# examle below will be excecuted every 15 minutes
# */15 * * * * python /home/pi/433/openweather_client.py Berlin > crontab_ow_client.log 2>&1
Client
download: openweather_client (besser die Datei herunterladen, da mit copy und paste man evtl. die berüchtigten “indentation” Probleme bekommt).
Update: api key eingefügt – wie im Kommentar unten beschrieben. Vielen Dank Christoph.

openweathermap verlangt inzwischen bei der Abfrage einen API-Key. somit hab ich folgende Zeile eingefügt :
ow_appid = ” your api-key” //muss man bei openweathermap generien es reicht der kostenlose!
und die folgenden verändert:
ow_url_cur = ow_url_api + “weather?q=” + ow_city + “,” + ow_country + “&appid=” + ow_appid
ow_url_fcst = ow_url_api + “forecast?q=” + ow_city + “,”+ ow_country + “&appid=” + ow_appid
des weiteren hat python noch ein paar identationen bemängelt, die ich korrigiert habe.
Welche Raspberry Pi Version hast du verwendet?
Das 1 script openweather_client.py habe ich jetzt auf zwei Versionen laufen lassen – funktioniert auf beiden Versionen:
cat /etc/os-release
PRETTY_NAME=”Raspbian GNU/Linux 7 (wheezy)”
PRETTY_NAME=”Raspbian GNU/Linux 8 (jessie)”
