Bambu Lab P2S

Der Drucker wird nicht direkt angesprochen. Ein Node-RED-Flow spricht mit dem Drucker und veröffentlicht dessen Werte retained auf dem MQTT-Broker von nomos. Dieses Profil liest diese Werte und schickt Befehle an den Flow zurück.

Einrichtung

1. Den P2S in den LAN-Modus schalten und IP-Adresse, Seriennummer und Zugangscode notieren (Druckerdisplay)
2. In nomos das Node-RED-Panel öffnen
3. Den folgenden Flow importieren:

4. Im Flow die Platzhalter ersetzen:
   • Broker-Konfiguration Bambu P2S: PRINTER_IP durch die IP des Druckers, Benutzer bblp, Passwort = Zugangscode
   • Broker-Konfiguration nomos Controller: die MQTT-Zugangsdaten des Controllers, falls der Broker welche verlangt
   • Knoten P2S report und → P2S request: BAMBUSERIAL durch die Seriennummer des Druckers
   • Weist der Drucker die Verbindung ab, am Drucker den Entwicklermodus einschalten
5. In der nomos Konfiguration unter Skills → Add-ons das Bambu Lab P2S-Profil importieren
6. Gerät anlegen
7. Einen Namen vergeben und bambu/p2s als MQTT-Topic eintragen (die Topic-Wurzel, die der Flow verwendet)

Werte, die der Flow veröffentlicht

Alle Topics sind relativ zum MQTT-Topic des Geräts (also z. B. bambu/p2s/state).

summary (JSON) wird vom Profil nicht gelesen.
