#Version IronPython 3.4)
#EXE tournant en boucle : interroge la Temperature Camera toutes les X secondes (5 par défaut) et envoie requête Allumage/Extinction Frigo si Température trop éloignée de la température cible
#V2 : ajout fenetre fixe pour suivre fonctionnement appli et fermeture si besoin
#V3 : ajout fichier de config json
