Protocol

broadcast message

I sniffed to protocol using TCP dump.

Changing the state of the lamp by the app causes a message to be sent to (TCP): ec2-3-121-210-75.eu-central-1.compute.amazonaws.com.8886

The local protocol appears to use UDP. There is an UDP broadcast message sent by the lamp of 172 bytes.
