IOBroker mit ESPHome und MODBUS Wind Anemometer

leonundjulie

Diesmal geht es um die Idee mit entsprechenden Sensoren alle möglichen Wetterdaten einzusammeln - unter anderem Windrichtung und Windgeschwindigkeiten.

Ich nutze einen PI 4 auf dem ich iOBroker nutze mit diversen Adaptern und möchte in meinem Szenario Wind Speed & direction via ESPHome und Modus abgreifen.

Eckdaten zu den Sensoren:

Wind speed transmitter (485type) SN-3000-FSJT-N01 https://robu.in/wp-content/uploads/2024/10/12-R183268-SN-3000-FSJT-N01-485-type.pdf

Das folgende Bild ist nur zur Info:

Also habe ich den ESPHome Adapter in iOBroker integriert, mir eine nodemmcu v3 gekauft, die Windsensoren und mein erstes YAML aufgesetzt. Es wird alles ohne Fehler kompiliert und der ESPHome arbeitet grundsätzlich. Da ich aber keine Kommunikation mit meinen Wind-Devices hinbekomme bin ich jetzt auf der Fehlersuche.

Das log des ESPHome zeigt folgendes und da irritieren mich die Warnungen - muss ich da was machen? Oder kann ich das ignorieren. Letztlich sehe ich an der flackernden LED des TTL-RS485, dass mein YAML arbeitet, etwas an den Konverter gesendet wird

Habe ich ein iOBroker unabhängiges Problem? Also ein Problem meiner ESPHome Umgebung? Im ESPHome-Forum habe ich kaum Feedback erhalten außer “*das Thema sollte auf Grund der Fehlermeldung eher in der iOBroker Welt besprochen werden”*italicised text

Hat jemand eine Idee?

Um es kurz zu machen: ich habe folgendes geändert damit es funktioniert.

habe ich den ESP8266 nodemcu v3 gegen einen ESP32-S3 getauscht
habe ich heraus gekitzelt, dass diese Devices nicht mit READ, sondern mit HOLDING register arbeiten.

Mit folgender YAML-Konfiguration läuft jetzt alles:


uart:
  rx_pin: GPIO44
  tx_pin: GPIO43
  baud_rate: 4800
  parity: NONE
  stop_bits: 1
  data_bits: 8
  //  debug:
  //  direction: BOTH
  //  dummy_receiver: true
  //  sequence:
  //     - lambda: UARTDebug::log_hex(direction, bytes,':');
