\title Generic MQTT
\brief Plugin for catching UDP commands from the network.
\ingroup plugins
\ingroup nymea-plugins-maker
This plugin allows to receive UDP packages over a certain UDP port and generates an \l{Event} if the message content matches
the \l{Param} command.
\note This plugin is ment to be combined with a \l{nymeaserver::Rule}.
\section3 Example
If you create an UDP Commander on port 2323 and with the command \c{"Light 1 ON"}, following command will trigger an \l{Event} in nymea
and allows you to connect this \l{Event} with a \l{nymeaserver::Rule}.
\note In this example nymea is running on \c localhost
\code
$ echo "Light 1 ON" | nc -u localhost 2323
OK
\endcode
This allows you to execute \l{Action}{Actions} in your home automation system when a certain UDP message will be sent to nymea.
If the command will be recognized from nymea, the sender will receive as answere a \c{"OK"} string.
\chapter Plugin properties
Following JSON file contains the definition and the description of all available \l{DeviceClass}{DeviceClasses}
and \l{Vendor}{Vendors} of this \l{DevicePlugin}.
For more details how to read this JSON file please check out the documentation for \l{The plugin JSON File}.
