Merci pour ce petit post 
car c'est exactement ce que je veut faire sauf que la c'est pour une sonde ds18b20 et j'aimerais aussi ajouter des interrupteurs et pouvoir actionner actionner des relais ... etc
Donc ton code me semblais une bonne base cela dit en passant je suis vraiment noob de chez noob en code et du coup je galère pas mal et la j'ai une erreur a la con car j'essaye forcement de rajouter des truc et ca plante
l'erreur c'est ca :
sketch_sep11a.ino: In function ‘void httpRequest(String)’:

Voila si une ame charitable pourrais me dire pourquoi mon celsius est hors perimetre par ce que moi je capte pas :s
