UI: OTA Management Page

[rodneyosodo]

Summary

The backend supports OTA updates (download, verify, replace, restart) and publishes progress to m/{domain}/c/{ctrl}/ota/status. There is also a new OTA abort capability (#35). However there is no UI page for triggering or monitoring OTA updates — it is only accessible via MQTT or direct HTTP API calls.

What to build

• Add an OTA page at /ui/ota
• Add a nav entry in the sidebar/topbar
• OTA trigger form:
  • Firmware URL input
  • Expected SHA-256 hash input (optional)
  • Expected size input (optional)
  • "Start Update" button
• Progress display:
  • State badge (idle / downloading / verifying / ready / restarting)
  • Progress bar (percentage from ota_progress field)
  • Bytes downloaded / total
• "Abort" button (cancels in-progress download, depends on Add OTA Abort to Cancel In-Progress Update #35)
• Status history log (last N status messages)
• Current firmware version display

Depends on

• Add OTA Abort to Cancel In-Progress Update #35 (OTA Abort) — for the abort button
