Jahresrückblick 2025 – unser neuer Blogbeitrag ist online! ✨

[Chronos81]

Hallo zusammen ich habe eine iobroker Installation via Docker auf meinem OMV Server installiert. Hier habe ich 2 Datenpunkte welche über einen HTTP request aus einem python skript befüllt werden sollen. Das Skript läuft auf einem RaspberryPi welcher sich ebenfalls im gleichen Netzwerk befindet. Das hat auch schon mal geklappt. Allerdings musste ich nun den IOBROKER neu aufsetzen und nun klappt es nicht mehr.
Ich habe den benötigten Port offen und die Datenpunkte passen auch. Leider kann ich jedoch keine Verbindung aufbauen.
Habt ihr mir einen Tipp woran das liegen kann?

Hier der Ausschnitt des requests:

        url = "http://192.168.0.10:8087"
        point = "0_userdata.0.Heizoel.dp_fullwert"
        cmd = "/get/"


        apiurl_1 = url + cmd + point
        print(apiurl_1)

        headers = {'Content-Type': 'text/html'}
        payload={}

        #Making http post request
        response = requests.request("GET", apiurl_1, headers=headers, data=payload)
        print(response.json())

 cmd = "/set/"
        value = "?value=66"
        apiurl_2 = url + cmd + point + value
        print(apiurl_2)
        payload={}

        response = requests.request("GET", apiurl_2, headers=headers, data=payload)
        print(response.json())

        response = requests.request("GET", apiurl_1, headers=headers, data=payload)
        print(response.json())

        #HTTP Request für Heizoel Liter

        url = "http://192.168.0.10:8087"
        point = "0_userdata.0.Heizoel.dp_liter"
        cmd = "/get/"


        apiurl_1 = url + cmd + point
        print(apiurl_1)

        headers = {'Content-Type': 'text/html'}
        payload={}

        #Making http post request
        response = requests.request("GET", apiurl_1, headers=headers, data=payload)
        print(response.json())

        cmd = "/set/"
        value = "?value=666"
        apiurl_2 = url + cmd + point + value
        print(apiurl_2)
        payload={}

        response = requests.request("GET", apiurl_2, headers=headers, data=payload)
        print(response.json())

        response = requests.request("GET", apiurl_1, headers=headers, data=payload)
        print(response.json())

        #HTTP Aufruf beendet

Das geschieht beim Ausführen:
./heizoeltestiobrokerresetvalues.py

[arteck]

@chronos81 du brauchst den simple.api adapter oder den web.. der hat die includiert

[Chronos81]

@arteck Asche über mein Haupt. Jetzt sitze ich da gestern 3h dran und habe nicht gemerkt dass ich den IOBROKER über ein Backup installiert habe in dem ich den SIMPLEAPI Adapter noch gar nicht installiert hatte.
Super das war meine Rettung. Danke.
