MqttPahoExamples

Simple examples to demo paho.mqtt.client and test a MQTT Broker. Not that environment variables are used to have settings config/passwords in source file, see below for details.

Dependances

This code has been developed on the Python 3.8.3 and uses paho-mqtt and dotenv (this code can be removed and values set directly in code if preferred)

• pip install paho-mqtt
• pip install -U python-dotenv

Using .env file

If leaving the code as is you need to define values for the broker, topic, etc. in a .env file (or set OS environment variables) in the same folder as the script files. This could contain key value pairs such as:

• MQTT_BROKER="192.168.X.X"
• MQTT_TOPIC="test/hello"
• CLIENT_USER="user"
• CLIENT_PWD="password"

See dotenv on GitHub for more details.
