Most of the IOT platforms do not support OCPP protocol unfortunately. But you can still implement IOT connectivity for those devices with the power of python. As seen in the example below a small python gateway implement to convert OCPP message payload to MQTT.<\/h1>\n

`import paho.mqtt.client as mqtt<\/p>\n

Define a function to handle incoming OCPP messages<\/h3>\n

def handle_ocpp_message(message):
\n# Extract the OCPP message payload
\npayload = message[\u2018payload\u2019]<\/p>\n

# Convert the OCPP message to a MQTT message
\nmqtt_message = {
\n\u2018topic\u2019: \u2018ocpp\/message\u2019,
\n\u2018payload\u2019: payload,
\n\u2018qos\u2019: 0,
\n\u2018retain\u2019: False
\n}<\/p>\n

# Publish the MQTT message
\nmqtt_client.publish(mqtt_message)<\/p>\n

Create an MQTT client<\/h3>\n

mqtt_client = mqtt.Client()<\/p>\n

Connect the MQTT client to the MQTT broker<\/h3>\n

mqtt_client.connect(\u2018localhost\u2019, 1883)<\/p>\n

Start listening for OCPP messages<\/h3>\n

ocpp_client.on_message = handle_ocpp_message
\nocpp_client.listen()`[\/vc_column_text][vc_single_image image=”6377″ img_size=”full”][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
