Hi zusammen.
Kurz zur Info: Ich habe eine “neue” Kältebringer Trio-Klima-Split (vll. 4 Wochen). Ich habe jetzt nach weiterer Recherche den folgenden Thread (Midea branded AC’s with ESPhome (no cloud) - ESPHome - Home Assistant Community) gefunden, mit dem ich es geschafft habe den ESP per 4xJumper-Kabel direkt an den 4-Pin-Anschluss anzuschließen und zu steuern!
Jetzt muss ich das nurnoch sauber angelötet bekommen und dann sollte das laufen.
Danke für eure Hilfe und Gruß,
Aezaekiel

Angeschlossen ist er wie folgt (am Board von Oben nach Unten):
| Kabel/Klemme | Anschluss am D1 Mini |
|---|---|
| SCHWARZ | GND |
| GRAU/BRAUN | TX |
| GELB/ORANGE | RX |
| ROT | 5v |
Vermutlich waren in meinem ersten Versuch TX und RX vertauscht oder die Konfiguration falsch.
Ich hoffe, das hilft dem Ein oder Anderen hier.
