Bonjour,
je vous propose aujourd’hui la réécriture en DZvents du script qualité de l’air dans le monde
Pourquoi ce script alors que le précédent fonctionne très bien?
Ce nouveau script apporte son lot de nouveautés :
- récupération automatique des données de localisation renseignées dans les paramétrés de domoticz
- possibilité d’agréger plusieurs stations proches pour ajouter les mesures non présentes dans celle qui est la plus proche de chez vous
- possibilité de récupérer, en plus des données de pollution, des données météo disponible telles que : température, hygrométrie relative, vent et rafale de vent, pression, pluie, pression atmosphérique et température de rosée
- possibilité de paramétrer plusieurs devices pour une même donnée de pollution : custom sensor, alerte, qualité de l’air
tout cela avec une API gratuite.
le script complet pour Domoticz
--[[ ~/home/pi/domoticz/scripts/dzVents/scripts/airQuality.lua
Based on this script : http://www.domoticz.com/forum/viewtopic.php?f=59&t=22080&start=20#p216650
Minimal dzVents Version: 2.4.19
auteur : papoo
MAJ : 10/06/2019
création : 08/06/2019
Principe :
Ce script a pour but d'interroger l'API du site http://http://aqicn.org pour récupérer les informations de pollutions
Cette API utilise une clé gratuite, Il faut donc s'incrire sur http://aqicn.org/data-platform/token/ pour avoir accès à cette clé de 40 caractères
data from http://waqi.info/
An API key is required and can be aquired here ==> http://aqicn.org/data-platform/token/
