v1.2.0

This release fixes several reliability bugs, brings the integration in line with
current Home Assistant guidelines and removes about a third of the code.
All entity unique IDs are unchanged, so existing entities, automations and
history are kept.

⚠️ Breaking changes

• Minimum Home Assistant version is now 2024.12.0 (was 2024.1.0).
• Entity display names changed. Entities now use Home Assistant's
  has_entity_name naming and translated names, so a friendly name is the
  device name plus a short, translated suffix (e.g. Living Summer comfort
  setpoint, or Soggiorno Setpoint comfort estate in Italian). Entity IDs are
  not changed for existing installations; only the names shown in the UI are.
• The empty switch platform was removed (it never created any entity).

Fixed

• Options flow broken on recent Home Assistant versions. The options flow
  set config_entry explicitly, which Home Assistant deprecated and then
  stopped supporting.
• Changes took up to 5 minutes to show up. Global status and timers were
  only re-read every 5 minutes (dehumidifiers every 60 s), even right after
  a change made from Home Assistant, so the season, timer slots, boost timer and
  dehumidifier override jumped back to the old value in the UI. A write now
  forces an immediate re-read of the resource it changed.
• Stale data shown as current when the API is down. When the zones request
  failed, entities fell back to the values captured at startup, possibly
  hours old, and never became unavailable. Now:
  • if zones or global status cannot be read, the update fails and the entities
    become unavailable until the API answers again;
  • if dehumidifiers or timers cannot be read, their last known values are kept
    and the request is retried on the next poll;
  • if the API is unreachable at startup, setup is retried automatically
    (ConfigEntryNotReady) instead of loading with no entities.
• Timeouts were not handled. An API timeout (asyncio.TimeoutError, not an
  aiohttp.ClientError) aborted the whole update and caused unhandled
  exceptions in the config flow. Timeouts are now handled like any other
  connection error.
• Custom station name was overwritten. Station-level entities re-registered
  the station device as Alterego <station id>, replacing the name chosen during
  setup. Renaming the station from the options now also updates the device.
• Entities ignored the connection state. The dehumidifier override select
  was always available; the humidity setpoint, boost timer and timer slot time
  entities also ignored failed updates. They now become unavailable with the
  rest of the integration.
• Selecting N/U on an active timer slot sent N/U hh:mm instead of N/U.
• Selecting heat/cool on a zone in COMFORT or ECONOMY reset it to AUTO. It
  now only changes the forcing when the zone is OFF.
• Target temperature parsing. A 0.0 setpoint (no active setpoint) was only
  ignored when sent as a string; numeric values are now handled too.
• Authentication errors. A server error (5xx) during login is no longer
  reported as "invalid credentials", and a 401 that persists after
  re-authentication is now treated as an authentication error.
• Translations. The options and reconfigure forms had no labels because
  their translations were in the wrong place; strings.json was out of date;
  the station ID form mentioned a comma-separated list of stations that was
  never supported; reconfiguring showed "Re-authentication completed" instead
  of "Reconfiguration completed".
• Dehumidifier device model switched between deum and Deumidificatore
  depending on which platform loaded last; it is now always Dehumidifier.

Added

• Re-authentication flow. If the Alterego credentials stop working, Home
  Assistant shows a repair notification asking for the new password instead of
  failing silently.
• Climate turn_on / turn_off (ClimateEntityFeature.TURN_ON /
  TURN_OFF).
• Clear error messages in the UI when a change cannot be sent to the API,
  or when a summer-only setting is changed in winter.
• Italian and English names for all entities, including timer slots
  (Monday slot 1 / Lunedì fascia 1).
• Boost timer now has a unit (minutes).
• Test suite (tests/, pytest + pytest-homeassistant-custom-component)
  covering setup, polling, failures, writes, config/reauth/reconfigure/options
  flows and the API client.
• CI workflow running hassfest, HACS validation and the tests.

Changed

• Uses Home Assistant's shared HTTP session instead of creating its own.
• Uses entry.runtime_data, _get_reauth_entry / _get_reconfigure_entry and
  async_update_reload_and_abort instead of the older patterns.
• Uses via_device_id on Home Assistant 2026.8+ (the via_device key is
  deprecated there and will be removed in 2027.8), and still uses via_device
  on older versions.
• PARALLEL_UPDATES = 1 on platforms that write to the API, to avoid
  concurrent writes to the cloud.
• Refactor: new entity.py with shared base classes (station, zone,
  dehumidifier, timer slot) and coordinator helpers replace code that was
  duplicated in every platform; the API client uses a single request path for
  all endpoints.
• manifest.json: removed the unnecessary aiohttp requirement (shipped with
  Home Assistant), fixed codeowners (@itsjustdeepred), added
  issue_tracker.
• hacs.json: removed keys HACS no longer uses.
