Port série sonoff Dual R2

Hello a tous !

Pour commencer meilleurs voeux a tous :wink:

Je souhaiterai récupérer le port Rx d’un sonoff dual R2, initialement prévu pour le formatage vers tasmota ou esphome pour brancher un pitinfo via esphome pour récupérer les infos du compteur.

Mais cela ne marche pas … Après des recherches j’ai trouvé que c’était le port GPIO3 mais aucune info ne remonte.

Je viens d’essayer avec un esp8266 les infos remontent correctement.

J’ai vu aussi sur internet que certains avais réussi à brancher un DHT22 sur ces ports mais via tasmota et je préférai rester sur esphome.

Est-ce que quelqu’un a deja eu le cas sur ce sonoff ?

Merci d’avance :wink:

Attention les GPIO des ESP ne peuvent pas être utilisés directement comme port série car ce ne sont pas les bons niveaux logiques ! Il faut un circuit adaptateur entre les deux…
Peux-tu partager aussi le code ESPHome que tu as essayé ?
