//       Version 1.0.5
//       Librairie LibTeleInfo : Allocation statique d'un tableau de stockage 
//           des variables (50 entrées) afin de proscrire les malloc/free
//           pour éviter les altérations des noms & valeurs
//       Modification en conséquence des séquences de scanning du tableau
//       ATTENTION : Nécessite probablement un ESP-8266 type Wemos D1,
//        car les variables globales occupent 42.284 octets
//
//       Version 1.0.5a (11/01/2018)
//       Permettre la mise à jour OTA à partir de fichiers .ino.bin (Auduino IDE 1.8.3)
//       Ajout de la gestion d'un switch (Contact sec) relié à GND et D5 (GPIO-14)
//          Décommenter le #define SENSOR dans Winfo.h
//          Pour être utilisable avec Domoticz, au moins l'URL du serveur et le port
//          doivent être renseignés dans la configuration HTTP Request, ainsi que 
//          l'index du switch (dans Domoticz)
//          L'état du switch (On/Off) est envoyé à Domoticz au boot, et à chaque
//            changement d'état
//       Note : Nécessité de flasher le SPIFFS pour pouvoir configurer l'IDX du switch
