v0.4.0

Highlights since v0.3.0:

• App-started sessions stay "on" through the hold phase. Follow-up to the
  v0.3.0 heat-up fix (#33). When a Harvia sauna is started from the app, the
  heater PID-cycles at target temperature and every on/off signal goes briefly
  quiet between pulses, which could make the card and badge blip to off
  mid-session — power chip off, a spurious cool-down curve, and the button
  offering to start a session already running. A hold-phase running latch now
  bridges these brief gaps near target, while still releasing promptly on a real
  cool-down, grace expiry, or an explicit stop from the card, the app, or the
  physical switch. Stops are mirrored across the card and badge together. (#34)

Note: the latch's grace window is set conservatively (10 min) and will be
validated against real hold-phase PID gaps; if a longer gap is observed a small
point release will tune it.

v0.3.0

Highlights since v0.2.0:

• ha-harvia-sauna v2.8.0 support — new statistics/connectivity value-catalog items (sessions_week, last_session_energy, records, cloud_connection, ready_at, planned_start) and the ambilight switch; the ready-ETA prefers the live time_to_ready sensor.
• Climate presets (show_presets) and smart preheat (show_preheat) — preset chips that apply temperature/duration, and a "ready by" scheduling control.
• Remote-off action (remote_off_action) — choose how the card reacts when remote control is disallowed or the door is open: disable start, lock, hide, or switch to compact.
• Manual entity mapping (integration: manual) — use the card with any sauna, not just Harvia.
• Whole-session graph on by default, and a cool-down curve that reconstructs after a page reload out of the box.
• Open door blocks start (same treatment as a remote-off block).
• Sessions started outside the card (e.g. the Harvia app) are now recognized: on/off is derived from heat_on, real power draw and the per-session ready latch, so the card shows heating instead of off/cooling, the button stops the session, and the remaining-time tile falls back to a live "ready in N min".

0.3.0-beta2

Second beta on the 0.3.0 line. Includes everything from beta1 (manual entity mapping) plus two new features and graph-default improvements. Cut from dev.

New since beta1

• Remote-off action (remote_off_action, default disable_start): when your "remote control allowed" sensor is off (and the sauna is off), the card reacts. The status pill swaps its icon for a lock (a visual cue, no tooltip needed), and you choose what happens: disable_start (default — disable just the start button), lock (disable all controls), hide_controls (display-only), compact / compact_locked (switch to the compact layout). none opts out. Only engages when such a sensor exists and reads off, so it is safe by default.
• Whole-session graph on by default (cooldown_include_heatup): a session now shows the rising heat-up and falling cool-down as one two-tone arc out of the box.
• Cool-down survives a page reload without configuration: the target falls back to the room temperature (or ~25 °C when unknown), so the falling curve reconstructs after a reload.
• Editor toggles tell the truth: the graph and "tap for more info" toggles now show their real (on) defaults instead of appearing off.

Install (HACS)

Enable beta/pre-release versions for sauna-card in HACS, then update to 0.3.0-beta2.

Feedback

Enable Advanced → Debug logging and post symptoms + the [sauna-card] console lines to issue #25: #25

0.3.0-beta1

Pre-release for testing the new manual entity mapping (use the card with any sauna, not just Harvia). Cut from the dev branch.

New in this beta

• Manual mapping (integration: "manual"): point the card at your own entities. A single climate entity is enough (current/target temperature, status, the stepper and on/off); add switches and sensors as you like. Built for DIY / KNX / non-Harvia saunas.
• Editor: a Source picker, and a foldable Entity mapping list right under it — tick each type your sauna has and pick (or type) the entity.
• Advanced section: a debug-logging toggle and a console version banner, to help diagnose setups.
• Companion badge supports manual mapping too.
• New Integrations and compatibility docs.

Install (HACS)

Enable beta/pre-release versions for sauna-card in HACS, then update to 0.3.0-beta1. (HACS hides pre-releases unless you opt in.)

Feedback

If something does not show as expected, enable Advanced → Debug logging and post the symptoms + browser-console output (the [sauna-card] lines) to issue #25: #25

0.2.0

Added

• Tap a value to open more-info. Read-only displays — the metric tiles, compact slots, the big current-temperature number, the status badge, and the static target temperature — open Home Assistant's standard more-info dialog for the underlying entity. Interactive controls are unchanged. Turn it off with tap_more_info (on by default).
• Heatup / cooldown temperature graph. A live rising curve while heating and a falling curve while cooling down, backfilled from the recorder so it covers the whole session. Toggles: show_heatup_graph, show_cooldown_graph (both on by default).
• Cooldown target temperature (cooldown_target_temp) — the temperature the cooldown tracks toward; also lets the cooldown be reconstructed after a page reload.
• Whole-session arc (cooldown_include_heatup) — one two-tone curve over the entire session.
• Time axis under the graph (start / middle / end clock times).

Changed

• Faster rendering on large installs. Device detection and entity-id resolution are scanned once per entity-registry change instead of on every render. No behaviour change.

Fixed

• Even spacing around the controls in the thermostat-dial and compact layouts.

Full notes in CHANGELOG.md.

0.1.1

Maintenance release.

Added

• Start feedback when a session can't start. If a start is refused — most often because the door is open — the card now says so instead of the controls silently blinking back to off: a notice appears the moment you press start with the door open, and a short grace later if the start otherwise didn't take.
• The card is offered for every Harvia entity in the card picker, not just the thermostat — sensors, binary sensors, numbers, and the integration's update entity. This includes the HACS update entity (the one that shows when you search "harvia"), which pre-fills the right sauna device.

Fixed

• Heating "ready in" estimate now counts down. It previously showed the integration's heat_up_time sensor, a static value (unchanged even while the sauna is off), so it never decreased. The estimate is now derived from the temperature trend — the temp_trend sensor when enabled, otherwise the card's own observed temperature — and shrinks as the sauna heats.

0.1.0

First release of sauna-card — a Lovelace card and badge for Home Assistant that show and control Harvia sauna heaters (Xenio / Fenix via ha-harvia-sauna).

Highlights

• Card with three theme-first layouts: status dashboard, thermostat dial, and compact.
• Companion badge with six appearances (chip, icon, value, and three gauge variants) and three content modes.
• Configure what every layout shows from the full set of integration values (44, diagnostics included): reorderable dashboard/thermostat tiles, compact left/middle/right slots, and a controls option — each saved per layout.
• Auto-detection, a visual editor, and a card-picker suggestion on Home Assistant 2026.6+.
• Multilingual: Swedish, Finnish, English, German.

See the README and docs/ for installation and configuration.
