[DzVents] Luminosité théorique extérieure

[lmet]

Bonsoir,
A priori il n'est plus possible d'obtenir une clef API gratuite auprès de WU même après création d'un compte.
J'ai probablement mal lu ...
Si une autre solution existe, d'avance merci

[Neutrino]

Bonjour,
C'est le problème du cloud...
Il doit être possible d'utiliser DarkSky à la place.
Au final, WU n'est utilisé que pour récupérer la pression relative.
Le reste (longitude, latitude, station WMOID) peut être renseigné manuellement.

Bonjour

J'essaie de mettre en place ce script en suivant le tuto ainsi que celui-ci

http://www.domoticz.com/wiki/Real-time_ ... structions


j'ai comme message d'erreur:

2018-06-04 15:25:02.800 Error: EventSystem: in script_time_SolarSensor.lua: [string " --[[ Virtual Lux sensor and other rea..."]:137: attempt to index field 'current_observation' (a nil value)

a votre avis

[Neutrino]

Tu as une clé API Weather Underground ?
Comme dit plus haut, ils n'en délivrent plus depuis quelques jours.
Pour contourner, il suffit de récupérer la valeur de la pression d'une autre manière.
Soit via un capteur local, soit via un autre hardware comme celui de DarkSky.

[vr6man]

oui j'ai une clé API depuis un bon moment

elle fonctionne je m'en sert pour récupérer des prévisions météo

[Neutrino]

ok, il y a quoi à la ligne 173 ?
Dans l'idéal, poste ton script entre les balises

    -- Autors  ----------------------------------------------------------------

    V1.0 - Sébastien Joly - Great original work

    V1.1 - Neutrino - Adaptation to Domoticz

    V1.2 - Jmleglise - An acceptable approximation of the lux below 1° altitude for Dawn and dusk + translation + several changes to be more userfriendly.

    V1.3 - Jmleglise - No update of the Lux data when <=0 to get the sunset and sunrise with lastUpdate

    V1.4 - use the API instead of updateDevice to update the data of the virtual sensor to be able of using devicechanged['Lux'] in our scripts. (Due to a bug in Domoticz that doesn't catch the devicechanged event of the virtual sensor)
