# UDP commander This plugin allows to receive UDP packages over a certain UDP port and generates an event if the message content matches the param command. > Note: This plugin is ment to be combined with a rule. ## Usage If you create an UDP Commander on port 2323 and with the command `"Light 1 ON"`, following command will trigger an event in nymea and allows you to connect this event with a rule. > Note: In this example nymea is running on `localhost` $ echo "Light 1 ON" | nc -u localhost 2323 OK This allows you to execute actions in your nymea 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 `"OK"` string. ## Supported Things * UDP Commander * Send UDP strings * Set target IP-address and port * UDP Received * Received UDP strings * Set receiveing port ## Requirements * The package “nymea-plugin-udpcommander” must be installed * The selected port must be available on the host system. ## More https://en.wikipedia.org/wiki/User_Datagram_Protocol
