Technical Details

what runs on :9522

SMA Speedwire is a proprietary protocol carried over UDP on port 9522; it has no TCP connection handshake. Devices use multicast discovery (commonly to 239.12.255.254) and exchange SMA-specific datagrams for device communication, monitoring, and supported control functions. It is intended for the local network, and packet details and protection features vary across SMA product generations.

5/ 10caution

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

network services averages 2.6 across 1,852 ports — this one sits 2.4 above.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

Do not expose this port directly to the internet: reachable Speedwire devices may disclose equipment or operating information, and some supported functions can affect system settings or operation. Keep it on a trusted, segmented network and do not assume every device generation encrypts or authenticates all Speedwire traffic.
