Einbindung elsner P03/ Modbus Wetterstation

SebastianIV

Hallo zusammen,

ich bin ganz neu hier und hoffe auf eure Hilfe. Derzeit verusche ich mit Hilfe des iobroker und einem RaspberryPi4 die elsner Wetterstation per Modbus einzubinden. Für die Kommunikation habe ich ein RS485 Shield gekauft. Im iobroker wird der Modbus Adapter grün aber ich habe keine Ahnung bzw. Anhaltspunkt wie ich die einzelnen Werte der Station abholen kann? Die Einstellungen der seriellen Schnittstelle am Pi habe ich angepasst. Hat hier zufällig jemand erfolgreich diese Wetterstation eingebunden? Wäre für jeden Tipp dankbar.

Vielen Dank im voraus.

Grüße
Sebastian

@sebastianiv Hat das Teil eine genaue Bezeichnung?

Gibt es eine Beschreibung der Modbus register?

@wendy2702
ja die gibt es. Anbei der Link

@sebastianiv Stimmen denn im ersten Schritt die eingestellten Übertragungsparameter mit den in der Instanz überein?

Achja, erkennt der Modbus Adapter das Shield überhaupt?

Hallo wendy. Der Adapter ist zumindest grün, ich gehe davon aus, dass dies bedeutet die Kommunikation steht?

Hier meine Einstellungen:

Hallo wendy, ich habe noch weitere Versuche unternommen, werde aber nicht schlau aus der Sache. Ich kann ein Objekt anlegen innerhalb der Holding Register aber sobald ich Poll anschalte, wird der Adpater gelb? Screenshot 2022-02-26 162148.png Screenshot 2022-02-26 162053.png

@sebastianiv Dann stelle den Adapter mal auf "Debug" und poste das log hier als Text in Code Tags </>

Hallo wendy2702, anbei das Log file. So wie es aussieht, meldet sich die Wetterstation nicht??

@sebastianiv Kannst du das loggen mal auf Debug stellen:

Die Adapter Einstellungen hier posten und auch das Logfile nach Adapter start.

Hallo wendy, sorry hat ein wenig länger gedauert. Anebi das log in debug. Ich hatte den Adapter schon das letzte Mal umgestellt aber erst nach deinem Psot gesehen, das es veraltete Daten waren...

@sebastianiv Poste mal einen Screenshot der Adapter Einstellungen.

Ist das RS485 Shield auch wirklich das Device „ttyAMA0“ ?

Hallo wendy, hier die Einstellungen vom Adapter. Ich h Screenshot 2022-03-07 165903.png abe mir parallel noch ein weiteres Shield bzw. Adapter für RS485 via USB gekauft, vielleicht funktioniert dieser besser....

wendy2702

Mach mal den Haken bei „Use Aliases“ weg. Kontrolliere danach die Register und poste dann mal das logfile.

Hallo wendy, ich habe nun Tests mit dem USB Adapter gemacht. Hier stellt sich die Thematik so dar, dass ich keine Antwort von der Wetterstation erhalte. Also die TX LED am Adapter geht an, die COM an der Wetterstation auch aber die RX am Adapter nicht. Um die Funktion der Wetterstation zu prüfen, wurde nun mit einem PC, dem Adapter via Docklight eine Kommunikation aufgebaut. Hier funktioniert alles, also auch die RX LED vom Adapter.

Hallo wendy, die Wetterstation läuft mittlerweile. Mit Hilfe des USB Adapter, dem richtigenm Einstellungen und Regsitern steht die Kommunikation. Einzig den Parameter des Regens bekomme ich nicht ausgelesen. Hast du hier vielleicht noch einen Tipp? Die Register zuvor funktionieren auch weil der Typ Signed 16bit (Big Endian) aus der Anleitung klar ist. Bei Regen habe ich alles möglich versucht aber nichts funktioniert?? Der WErt bleibt konstant bei 0..

Vielen Dank

@sebastianiv Blöde Frage, regnet es denn?

SebastianIV

@wendy2702
Nein ich habe aber versucht den Regen mit einem feuchten Lappen zu simulieren.
