This line creates an mqtt client id of "qt-openzwave-0". If you have installations across multiple machines, their mqtt-client-id will be duplicated on the MQTT server. Since an MQTT server can only have unique client-id's, the older connection gets kicked off. In my instance, I have a two instances running in Docker connecting to the same MQTT server, both trying to connect with the same client id.

1616742765: New connection from 172.18.0.1:50662 on port 1883.

1616742765: Client qt-openzwave-0 already connected, closing old connection.
Can this be changed so that there is a short random number instead of 0 to allow multiple instances to connect to a single MQTT server?
