Ich habe die Box in meinen Home Assistant eingebunden, funktioniert soweit ganz gut. Hier meine Konfiguration:

config/automations.yaml:
Die Automation ist leider notwendig, um das MQTT-Kommando der Wallbox richtig zu senden. Die Box hat zwei Topics zum Starten und Stoppen des Ladevorgangs, und Home Assistant unterstützt leider nur einen Topic für den Schalter. Funktioniert aber gut soweit.
Edit: Ich habe doch eine Variante ohne Automation gefunden, mit Hilfe eines Template-Switches.
