+This project is made up of two blueprints
+- `sunrise-simulation.yaml`: This script turns any compatible light (or group of lights) into a soft-sunrise / sunset alarm. It gradually ramps the brightness and the colour temperature over a user-defined period.
+- `sunrise-alarm.yaml`: Thin wrapper that calls the simulation script when the alarm occurs (or some configured time before/after).

 ## 1. What it is & how it works  
 
 | Component | Purpose | What it does |
 |-----------|---------|--------------|
-| **sunrise‑simulation** (script) | The “engine” that gradually lights up (or down) your bulbs | Uses a `repeat` loop to turn the selected lights on/off and slowly increase/decrease brightness over a configurable time span. |
-| **sunrise‑alarm** (automation) | The “scheduler” that calls the simulation at a chosen time | Triggers the script at *Alarm Time – Offset* (e.g. 30 min before the clock). An `input_boolean` lets you switch the alarm on/off. |

The brightness and color curves can be configured to create more natural-looking sunrises.  |

+> [!NOTE]
 > **Why two separate blueprints?**  
-> The simulation can be reused in any scenario (e.g. a “morning routine” or a “sunset‑in‑30‑min” routine). The alarm automation is a thin wrapper that turns that simulation into a timed alarm.

+> Scripts can also be stopped while the are executing, allowing you to stop the sunrise arc without turning the scheduler on and off.

 2. **Create a script from the blueprint**  
    * In the “Create new script” dialog, name it **`sunrise-simulation`** (you can give any name you like).  
-   * You’ll be asked for a handful of variables – see section 3.1 for the defaults and meaning.  
-   * Click **Create** – Home‑Assistant will add a script entity called `script.sunrise-simulation` (or whatever name you gave it).

 2. **Create the automation**  
    * Pick an `input_datetime` that represents the clock you want to use as the alarm.  
    * Pick an `input_boolean` that toggles the alarm on or off.
-   * Choose a `offset_duration`
-   * Choose the `sunrise‑simulation` script you created in the previous step for the `alarm_script` field.  
-   * Save – you now have a ready‑to‑run alarm!
+   * Choose an `offest_duration` for how long before/after to start the sunrise arc relative to the alarm time. You'll usually want this to be the same as `duration` defined in the previous script, this time _negative_, so that the peak (end) of the arc aligns with the alarm time.

-> **Tip** – If you want a *sunset* alarm, simply copy the  `sunrise‑simulation` script (or create a new script from the blueprint if you want to define a different arc)  and reverse it by setting direction with the `reversed` flag set to `true`. You'll also want to create a new automation that calls it with a negative `offset_duration`.

 The automation uses the following logic:
 
-1. `Alarm Time – Offset` fires the automation.  
-2. If `Alarm Enabled` is `on`, it calls the sunrise script.  
-3. If `Alarm Enabled` is `off`, nothing happens.

+> [!WARNING]
+> You may not be able to set negative duration values via the user interface. If so, you'll need to edit the YAML directly.
