 Diagnostics include a non-mutating dry-run endpoint/UI with a selectable simulation time, optional per-block sensor/state overrides, a per-node condition trace and an ownership/block reason. The Flow list also exposes a simpler scenario simulator beside the editor button: it uses live values by default and reduces the result to clear will-run / will-not-run / blocked outcomes with readable condition checks. Shared Home Assistant Flow inputs can also be tested directly in their editor against the current HA entity state. Flow-scoped execution and dry-run events can be viewed from the editor.

 Individual Flows can be exported/imported as versioned `gree-controller-flow` JSON. A saved Flow can be exported directly from its card in the Flow list without opening the editor, and its description can be edited there through a quick modal; the editor export remains available for saved and unsaved drafts. Generated schedules and automations are intentionally excluded from the portable document and are regenerated from the source graph on import. Incomplete Flows can also be saved as disabled drafts; drafts preserve the editor graph but intentionally generate no schedules or automations until completed and saved normally. Shared inputs show which Flows reference them and link directly to those editors. The preset library includes 37 categorized scenarios for comfort, energy, safety, night, reliability, Home Assistant heat-source coordination and advanced multi-branch logic.

-HTTP and WebSocket API for GREE Controller **0.16.1**.
+HTTP and WebSocket API for GREE Controller **0.16.3**.

-Version 0.16.1: Zone configuration exposes `heat_anticipation_c` (0..2.5°C, default 0), runtime Zone exposes `heat_coasting`, and optional Flow `zone_thermostat` node configuration supports `heat_anticipation_c` and `standby_offset_c`. These settings alter the GREE temperature target, not physical power.
+Version 0.16.3: the Flow editor adds localized descriptions and contextual examples for the two heating blocks; the API and heating behavior remain compatible with 0.16.2.
+
+Version 0.16.2: Flow adds the `zone_heat_cycle` action with `zone_id`, `day_target`, `night_target`, `day_min`, `boost_after_minutes` and `day_off_after_minutes`. An always-true Flow condition is sufficient. The Zone runtime stores the active `simple_heat` profile and timers; source `automation.flow` means automatic control, not manual. Nighttime modulation keeps the unit ON and uses 19/21/23 °C around a 20.6 °C target. Daytime power is OFF above the minimum until required, then OFF after 30 minutes at target. Existing `zone_thermostat` coasting options remain supported.

The action configuration takes `zone_id` (zone UUID), `day_target`, `night_target`, `day_min`, `boost_after_minutes` (3–30) and `day_off_after_minutes` (10–120). Day/night boundaries come from global Night Mode. The generated Flow automation owns an independent per-zone temperature policy; this is **automatic** ownership (`control_source=automation.flow`), not a manual `custom` preset. The measured temperature comes from that zone's configured GREE/HA/combined sensor.

+GREE modulation at a night room target of 20.6 °C: 21 °C for a moderate dip, 23 °C for a deep dip or no rise after the configured trial, 20 °C at 20.5 °C in the room, 19 °C at/above 20.6 °C. Nighttime physical power remains ON. During day the indoor unit is OFF while above `day_min`; after falling below it the unit heats and powers OFF after the configured continuous time at `day_target`.

+## Proste grzanie dzień/noc (od 0.16.2)
+
+Do jednego pokoju potrzebne są **tylko dwa bloki**: `Stała: Tak` → `Proste grzanie dzień/noc`.
+Blok ustawiasz na odpowiednią strefę oraz:
+
+- `day_target` – komfort w dzień (np. 20.0 °C), `night_target` – komfort w nocy (osobny dla każdego pokoju),
+- `day_min` – próg alarmowy w dzień (np. 19.7 °C); powyżej niego jednostka pozostaje **OFF** dopóki wcześniej nie zaczęła ratunkowego dogrzewania,
+- `boost_after_minutes` – czas próby delikatnego grzania (np. 10 min; Jan: 8 min),
+- `day_off_after_minutes` – czas ciągłego utrzymywania dziennego celu przed wyłączeniem (np. 30 min).
+
+Przebieg (dla celu 20.6 °C): noc: **20.6 °C → GREE 19 °C**, od 20.5 °C wyhamowanie **20 °C**, poniżej tego delikatnie **21 °C**; poniżej 19.8 °C lub po 10 minutach bez wzrostu o 0.1 °C grzanie **23 °C**. Przy celu innego pokoju nastawy GREE zmieniają się proporcjonalnie do celu, z zaokrągleniem do całych stopni. Jednostka pozostaje włączona w nocy (niższa nastawa pozwala jej się samoczynnie uspokoić).
+
+Dzień: przy celu 20.0 °C łagodna faza ustawia GREE na 21 °C, a pełna faza na 22 °C. Nad `day_min` jednostka jest fizycznie wyłączona. Przy spadku poniżej `day_min` podejmuje grzanie; po osiągnięciu `day_target` przez nieprzerwane `day_off_after_minutes` wyłącza jednostkę, z zachowaniem zabezpieczeń sprężarki. Jeśli w tym czasie cel zostaje utracony, odliczanie zaczyna się od nowa.
+
+**Ważne:** Ustawienia > **Tryb nocny** muszą mieć włączony harmonogram i prawidłowe godziny, ponieważ ten sam kalendarz ustala dzień/noc dla wszystkich stref. Temperatura pokoju pochodzi ze skonfigurowanego czujnika termostatu strefy (w tym czujnika HA/combined), a nie z osobnego warunku Flow. Pole `control_source=automation.flow` oznacza automatyczną kontrolę (nie ręczną), również gdy GREE jest w uśpieniu. Rzeczywisty pilot/ręczne sterowanie nadal ma pierwszeństwo.
+
+Gotowe importy: `flows/simple-heating/`. Po imporcie **wyłącz lub usuń oryginalne Flow v4**, żeby uniknąć konkurujących poleceń. Wyłączenie nowego Flow usuwa jego profil sterowania w następnym cyklu regulatora.
+
+### Pomoc w samych blokach (0.16.3)
+
+Po kliknięciu bloku **Stała testowa** edytor wyjaśnia, że wartość **Tak** jest bezwarunkowym sygnałem wejściowym w każdym cyklu, a **Nie** blokuje akcję. W bibliotece bloków oba nowe opisy są widoczne pod nazwami; w palecie i na schemacie pojawiają się jako podpowiedzi po najechaniu.
+
+W bloku **Proste grzanie dzień/noc** opis jest widoczny nad ustawieniami, a sekcja **Jak działa?** rozwija kolejne fazy: nocne uśpienie, hamowanie, delikatne i mocne grzanie, dzienny próg uruchomienia oraz warunek wyłączenia po stabilizacji. Temperatury przykładowe są wyliczane na podstawie rzeczywistych wartości ustawionych w edytowanym bloku, więc Jan, Igor i sypialnia mają poprawne progi. Opis obejmuje też dobór źródła pomiaru w strefie, zachowanie przy braku danych HA i pierwszeństwo sterowania ręcznego.
+
+Ta aktualizacja dotyczy **tylko pomocy UI**. Nie zmienia algorytmu, formatu eksportu Flow ani nastaw trzech wcześniejszych importów; nie trzeba ich ponownie importować.

 # Changelog

+## 0.16.3
+
+- Adds expandable, per-room examples for nighttime 19/21/23°C modulation, daytime OFF/boost/30-minute stability, zone temperature-source fallback and Flow vs manual ownership.
+- Adds tooltips explaining each day/night heating setting. No changes to runtime heating algorithms, saved Flow JSON schema or existing imported flows.
+
+## 0.16.2
+
+- Adds `zone_heat_cycle`: a single day/night room-temperature controller for one zone. Use a constant true condition plus the new block (two Flow nodes total).
+- Night: low demand first (typically GREE 21 °C), boost to target +2 °C after 8–10 minutes without warming or a deep temperature drop, brake 0.1 °C ahead and standby at ~19 °C when reached. Keep the indoor unit powered without repeated ON/OFF.
+- Day: physically OFF above the configured room minimum until heating is needed; maintain room temperature, then OFF after 30 continuous minutes at goal with compressor minimum-on protection.
+- Keeps individual targets for Bedroom, Jan and Igor; includes three ready-to-import two-block Flow definitions.
+- Correctly identifies Flow-owned thermostats as automatic, including day OFF/pending OFF and night standby; respects genuine manual control.
+- Adds focused Rust unit cases, UI ownership tests and a static release verification script. Rust tests/build still require a Rust toolchain on the CI/deployment host.
