Unfortunately, this is not possible. The devices must use port 80, as it is the port configured by the system to communicate with our server (api.sound-machine.com).
This port is used because it is the standard for HTTP connections and because the device software is specifically designed to operate through it.
At the moment, it is not possible to change this port, as doing so would require modifications to both the device firmware configuration and the server infrastructure.
For this reason, port 80 must remain open to ensure connectivity and the proper operation of the service.
However, this should not represent a significant security risk, since the communication is performed exclusively through outbound connections initiated by the device itself toward our servers. In other words, the device does not need to be exposed to inbound connections from the Internet.
