This blueprint is a modern evolution of Sbyx’s “Wake-up light alarm with sunrise effect” (Dec 2020).
Original gist: https://gist.github.com/sbyx/96c43b13b90ae1c35b872313ba1d2d2d
Huge thanks to Sbyx for the initial concept and implementation. The core idea—ramping brightness and color temperature towards the alarm time—remains, while this version modernizes the internals and expands usability.

Why a new version?
-
Future-proof color control
Home Assistant is deprecating the oldcolor_temp(mired) service parameter.
This blueprint usescolor_temp_kelvinend-to-end (with on-the-fly conversion when devices only expose mired ranges) to avoid warnings and ensure forward compatibility. -
Direct, user-friendly controls
Two dedicated Kelvin sliders (Start and End) model a natural sunrise: warm (~2200 K) → daylight (~6500 K). Values are auto-clamped to each light’s supported range. -
Optional RGB sunrise
Prefer color over Kelvin? Enable the RGB gradient and set Start/End colors via color pickers. If the light supports RGB, the blueprint uses it; otherwise it falls back to Kelvin or brightness-only. -
Clear UI descriptions
Every input has a concise description so users immediately know what each option does (time source, duration, conditions, quiet hours, etc.). -
Quality-of-life features
- Quiet hours window to suppress early triggers
- Check entity and Workday-only conditions
- “Turning off cancels” to stop the ramp instantly
- Step count control for smoother or lighter updates
- Works seamlessly with Light Groups for multi-lamp wake-ups
-
Template & timing robustness
Safer templating, explicit race-condition checks right before start, and consistent step timing.
How this differs from the original
- Uses
color_temp_kelvininstead ofcolor_temp(mired). - Adds Start/End Kelvin sliders and optional RGB start/end color pickers.
- Adds quiet hours, workday only, check entity, abort on off, and pre/post actions with descriptive UI.
- Exposes a step count for smoothness control.
Migration notes (from Sbyx’s blueprint)
- This is not a drop-in replacement; input names and options differ to provide clearer controls.
- Import this as a new blueprint and create a new automation from it. You can keep Sbyx’s version side-by-side.
- If you previously saw deprecation warnings about
color_temp, those are resolved here thanks tocolor_temp_kelvin.

Moderner Wecker mit Sonnenaufgangseffekt. Standard: warmes Weiß (≈2200 K) → tageslicht-weiß (≈6500 K),
automatisch an die Gerätegrenzen angepasst. Optional statt Kelvin eine RGB-Farbkurve von Start- zu Endfarbe.
Zukunftssicher dank color_temp_kelvin. Für mehrere Lampen bitte eine Light-Group wählen.
