Bonjour,
copie ton programme en mode programme car là on ne voit pas les problèmes de syntaxe et d’indentation
et donc ça me semble difficile de te répondre même si je ne suis pas expert!
Cordialement

J’ai sur mon breadbord un NodeMCU ESP32 kit un capteur température et humidité DHT22 ,un display 0.96 Oled et j’ai ajouté une Led que je peux allumer ou éteindre depuis le tableau de bord de HA
Merci d’avoir pris le temps de me lire et de me répondre
