This video demonstrates who a Python program can be created in GitHub Codespaces to subscribe to MQTT data. The Python program came from this site: https://medium.com/python-point/mqtt-basics-with-python-examples-7c758e605d4. The following lines were adjusted as per the following:
mqttBroker ="broker.hivemq.com"
client = mqtt.Client(mqtt.CallbackAPIVersion.VERSION2)
client.subscribe("sala306/tempws") #Note: you should make your topic unique
time.sleep(120)
