Après moult recherches sur le net voici un script PHP trouvé là calcul position du soleil • Scripts & Périphériques du store • Forum eedomus
Une implémentation dans l’IPX800 V5 avec une possibilité d’intégrer un masque d’ombrage sur 360° et position des volets également sur 360° par pas de 5° serait top pour piloter les VR en fonction de l’ensoleillement du jour et à l’heure précise ! Si cela tente certain pour le mettre en œuvre et faire des retours pour tous !!! Chapeau bas à l’auteur du script qui doit être chauve maintenant ! 
<?php
// Version v1.0
// CE SCRIPT EXPERIMENTAL REALISE EN PHP PERMET DE DETERMINER LA POSITION DU SOLEIL (AZIMUT + ELEVATION, ...)
// L'ALGORYTHME EST BASÉ SUR UNE ÉTUDE FAITE PAR LE National Oceanic and Atmospheric Administration
// LES VARIABLES DE LA BOX EEDOMUS:
// [VAR1] = @IP DE LA BOX
// [VAR2] = Latitude (+ => N)
// [VAR3] = Longitude (+ => E)
// Les latitude et longitude doivent contenir des "." (PAS DE VIRGULE)
// EXEMPLE: Latitude = 48.858346
// Longitude = 2.294496
// OU
//
// EXEMPLE: Latitude = 48.387942
// Longitude = -4.484993
// EXEMPLE APPEL DE SCRIPT avec variables: http://[VAR1]/script/?exec=position_soleil.php&latitude=[VAR2]&longitude=[VAR3]
// EXEMPLE APPEL DE SCRIPT dans navigateur: http://@IP_BOX_EEDOMUS/script/?exec=position_soleil.php&latitude=48.858346&longitude=2.294496
// LE RESULTAT EST SOUS FORME XML
// L'ELEVATION CORRESPOND A L'ANGLE ENTRE L'HORIZON ET LE SOLEIL
// XPATH ELEVATION: /Data/Soleil/Solar_Elevation_corrected_for_atm_refraction_deg
// L'AZIMUT CORRESPOND A L'ANGLE ENTRE LE NORD ET LE SOLEIL
// XPATH AZIMUT: /Data/Soleil/Solar_Azimuth_round
// 0°/ 360° = NORD
// 90° = EST
// 180° = SUD
