Need help with coding in script

[madpatrick]

import json

with open("test.txt", "r") as file:
    json_data = json.load(file)
    states = json_data["states"][0]["state"]

for state in states:
    print(
        "id =", state["id"][0], "value =", state["tempValue"][0], "dhw", state["dhw"][0]
    )

Output:
id = 0 value = 2000 dhw 1
id = 1 value = 1900 dhw 1
id = 2 value = 1700 dhw 1
id = 3 value = 1800 dhw 1
id = 4 value = 1000 dhw 1

Many thanks for your support.
This helped a lot

    def onMessagetoonSceneinfo(self, Connection, Response):	
        Domoticz.Debug("onMessagetoonSceneinfo called")
        if 'states' in Response:
            #this message contains the scenes
            Domoticz.Debug("onMessagetoonSceneinfo processing list of scenes")
            for state in Response["states"][0]["state"]:
                Domoticz.Log("id ="+ state["id"][0] + " Temp =" + state["tempValue"][0])

Output:
2023-02-04 09:58:02.200 Toon: id =0 Temp =2000
2023-02-04 09:58:02.200 Toon: id =1 Temp =1900
