Paho MQTT Python Client

The Mosquitto Python client was donated to the Eclipse Paho project in June of this year. As mosquitto.py has been very popular, I have been maintaining both code bases together.

With the Mosquitto project also moving to Eclipse it is now even more redundant to keep maintaining mosquitto.py so I would like to recommend that everybody currently using mosquitto.py move over to using the Paho Python client.

The current state of the Paho client is now available on pypi and can be installed using pip install paho-mqtt.

To port code from mosquitto.py, you should change:

import mosquitto
mqttc = mosquitto.Mosquitto()

to:

import paho.mqtt.client as paho
mqttc = paho.Client()

All error codes e.g. MOSQ_ERR_SUCCESS change to MQTT_ERR_SUCCESS.

The Paho module has a compatibility Mosquitto class that means a very simple (but not recommended for the long term) port can be achieved with the following line, assuming none of the error codes are used:

import paho.mqtt.client as mosquitto

I will keep applying updates to mosquitto.py until the Paho 1.0 release.
