1.0.1

Fluval BLE v1.0.1

v1.0.1 fixes the exact failure v1.0.0's Schedule Guardian could otherwise
hide: a permanently held Home Assistant connection locking the Fluval app
out of a fixture that only accepts one BLE central at a time.

Highlights

• hold_connection now defaults to off (connect-on-demand). Home
  Assistant connects only when it needs to - for commands and for the
  guardian's periodic checks - and disconnects again after the active
  connection window, leaving the fixture's single BLE slot free for the
  Fluval app the rest of the time. Turn the Bluetooth connection switch
  on (or set the hold_connection option) if you'd rather hold the link
  open permanently for the lowest possible command latency.
• Guardian supervision no longer stops when the connection isn't held.
  Previously, turning hold_connection off made every guardian check report
  "paused" without even attempting BLE traffic - silently disabling
  supervision the moment anyone used the connection switch as documented.
  The guardian now only pauses when expected_mode is explicitly set to
  Unsupervised; with the new default it keeps checking and correcting on its
  normal schedule, connecting on demand like everything else.
• Guardian status starts at "unknown", not "ok". The status sensor now
  accurately reports that no check has run yet instead of claiming things
  are fine before the guardian has looked.
• Stopped calling the deprecated device_registry.async_get_device(), which
  Home Assistant Core 2026.8+ logs a warning for; the integration now prefers
  the config-entry-scoped async_get_device_by_identifier() when the running
  Home Assistant provides it.

Upgrade notes

Existing installations pick up the new hold_connection default (off) on
upgrade unless you already changed it - if you specifically want Home
Assistant to keep holding the connection open, turn the Bluetooth
connection switch back on, or set hold_connection in Configure. No
other action is required.

If a fixture behaves differently after upgrading, include its exact model,
Home Assistant version, downloadable Fluval BLE diagnostics, and relevant
logs in a GitHub issue.
