Héllo,
Après 1 jour aucune reconnexion.
J'ai voulu le mettre en place en configuration réelle et le laisser plusieurs jours mais le programme d'origine n'enclenchait pas le relais de mise en marche.
J'ai donc revu le code en déclarant le relais sur la sortie 0 GPIO0 et en enclenchant le contact lorsque la led est allumée avec ``````digitalWrite(RELAY,LOW);```` et High sur la position OFF.
Tout à l'air de marcher à merveille. Demain je mets le nouvel ESP01 en place dans mon poulailler pour essai en réel sur plusieurs jours. Je vous tiens au courant.
Voici le nouveau code modifié pour celui qui en aurait besoin à l'avenir
