Mosquitto Broker

During installation, a MQTT broker, Mosquitto, may be installed at the same time as Domoticz. It's an optional setting: during install if you set the same domaine as your main app domain, it won't be installed. This broker requires a dedicated domain or subdomain to work (ex : mqtt.your.domain.tld) : creating this domain prior installation is a prerequisite

Installed Version

For now, domoticz project does not (yet) provide compiled binaries for each release. So, the installed release is a precompiled version from a project fork. The source code is exactly the same as the original version.
