I am trying to acheive a simple task, however i am confused because its not working. After watching your tutorial, I am trying the code below but i am not getting desired results. I want to turn the knob (Knob widget in Thingsboard) and plot the value set by knob. For instance, rotate the knob and show the value of knob on chart/card etc. The script is below, can you help me to identify where i am doing wrong?

#!/usr/bin/env python
import os
import time
import smbus
import sys
import paho.mqtt.client as mqtt
import json

THINGSBOARD_HOST = 'ourdevice.tk'
ACCESS_TOKEN = 'iJqpMTIULqzlMgU2QpAw'

def on_connect(client, userdata, rc):
client.subscribe("v1/devices/me/rpc/request/+")

def on_message(client, userdata, msg):
data = json.loads(msg.payload)
data = int (data)
client.publish('v1/devices/me/telemetry', data)

client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
client.username_pw_set(ACCESS_TOKEN)
client.connect(THINGSBOARD_HOST, 1883, 60)

try:
client.loop_forever()
except KeyboardInterrupt:
sys.exit()
