+## Logging on Ethernet
+
+When the device is connected to Ethernet, logs are broadcast over UDP to port 514. Use `ncat -ul 514` on your PC to view them live.
+*(If `ncat` throws a `WSAEMSGSIZE` error on Windows, use this Python command instead:)*
+```powershell
+python -c "import socket; s=socket.socket(socket.AF_INET, socket.SOCK_DGRAM); s.bind(('', 514)); [print(m[0].decode(errors='ignore'), end='') for m in iter(lambda:s.recvfrom(4096), None)]"
