Field notes
The described discovery flow checks a Wi-Fi subnet up to /24 across four listed ports and reads one register from each responding host. Monitoring supports up to 16 blocks, with polling from 1 to 60 seconds; failed polls appear as gaps in charts. The page also says profiles, logs, and scan results stay on the device until exported, with CSV files leaving through the share sheet.
