_Turn your smart lights into a natural alarm clock_
|
||||
|
||||
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-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).

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

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).

|

* 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.

1. `Alarm Time – Offset` fires the automation.

2. If `Alarm Enabled` is `on`, it calls the sunrise script.
