 # GREE Controller API reference
 
-HTTP and WebSocket API for GREE Controller **0.16.3**.
+HTTP and WebSocket API for GREE Controller **0.16.4**.
 
-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 0.16.4: disabled parent Flows suppress their generated automations and schedules throughout execution, API status and control plans. Newly enabled Flows restart their stateful timing gates. The zone response includes optional `flow_control_id` and `flow_control_node_id` as internal ownership diagnostics.
 
 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.

 - Thermostat hysteresis, compressor protection, schedule hand-back, manual/local ownership and Temporary Quick Thermostat keep their existing priority.
 - GREE fan/quiet/sleep and dry/fan HVAC modes are suppressed on thermostat-assigned devices when they would fight the regulator. Device-only features such as light/turbo/louver/air/xfan/health remain available through the normal command path.
 
+## Wyłączanie Flow / Disabling Flow (0.16.4)
+
+`Flow.enabled=false` and `draft=true` are authoritative: generated automations and schedules do not execute, create deadlines or contribute to the control plan even if a legacy/imported child record still says `enabled=true`. Runtime-only Flow checkpoints cannot overwrite `enabled`, resurrect deleted rules or persist across a Flow recompile. Actions recheck both their own enabled state and the parent Flow under the automation execution lock.
+
+Disabling, deleting or replacing a thermostat Flow releases zone-level thermostat intent attributed to that Flow (including stale manual setpoints and pending compressor actions) immediately during the Flow edit, with a regulator-cycle fallback for old/imported data. Manual/local takeover is never cleared. Single-shot device/group/HA commands that have already reached an external device/service are not retroactively undone; disable blocks **future executions**. Stateful timing counters, change-event latches, rolling samples and cooldowns start fresh when the Flow is enabled again; disabled time is not counted.
