Mosquitto 2.x included two significant changes from 1.6:
* There is no longer a "default" listener; all listeners are configured
in the same way
* The daemon drops privileges *before* reading TLS certificates and
private keys
*Mosquitto* implements an MQTT server. It is the recommended
implementation for using MQTT with Home Assistant.
I have added this role to deploy Mosquitto on the Home Assistant server.
It will be used to send data from custom sensors, such as the
temperature/pressure/humidity sensor connected to the living room wall
display.
