v1.13.4

Release v1.13.4

Release Date: 2026-05-21

Type: Patch release - Extends cold-restart energy-doubling protection to all 17 energy sensors.

What's Changed

Fixed

• Daily F1-F6 energy sensors could double-count after a Home Assistant restart -
  v1.13.3 protected only the 5 lifetime energy sensors from the cold-restart warm-up
  zero. The 12 daily time-band sensors (energia_{prelevata,immessa}_giornaliera_f1..f6)
  are also TOTAL_INCREASING and were left exposed — a warm-up 0 after a restart was
  read by HA's statistics as a meter reset and double-counted. All 17 energy sensors are
  now protected.

Changed

• Reworked cold-restart protection into a metadata-driven two-guard model (ported
  from the sibling ha-abb-fimer-pvi-vsn-rest integration). Each energy sensor carries
  a sensor_scope tag (lifetime or periodic); protection is derived from
  state_class and sensor_scope instead of a hand-maintained list. Two independent
  guards now run in the sensor's native_value:
  • Guard 1 — lifetime sensors may never decrease while a live state exists; daily
    sensors are excluded so their legitimate midnight reset still works.
  • Guard 2 — after a cold restart, any accumulating sensor whose value falls below
    its RestoreSensor baseline is held back through the device warm-up window.
    The restored baseline is now kept on the entity instead of being written back into the
    coordinator's data, removing a fragile coupling.
• RestoreSensor restore logic now applies only to the 17 accumulating energy sensors
  rather than every sensor.

Known limitation

• If Home Assistant restarts within the device warm-up window immediately after
  midnight, a daily F1-F6 sensor's genuinely-low post-reset value can be held back by
  Guard 2 until it re-accumulates past the pre-restart value. This is a rare edge case
  and matches the reference implementation's accepted behaviour.
