6. Known Issues and Hotfixes (As of May 4, 2026)

Despite extensive QA, the V2.0 release has three acknowledged bugs that will be patched in V2.0.1 (expected June 2026):

  1. NTP Sync failure over IPv6: If your network uses SLAAC-only IPv6 (no DHCPv6), the device fails to sync time. Workaround: Temporarily fall back to IPv4 or manually set NTP server to time.cloudflare.com.
  2. SD card hot-swap corruption: Removing an SD card while the UMB bus is active has a 3% chance of corrupting the journaling filesystem. Workaround: Always unmount via umount /mnt/sd before physical removal.
  3. Legacy Web UI glitch: The old Angular-based UI (deprecated but accessible) shows incorrect signal strength for LoRaWAN. Use the new React dashboard on port 8443 instead.
