A blueprint that gradually brightens your lights and changes their color temperature to simulate a natural sunrise over a customizable duration.

• 🌅 Natural sunrise simulation - Gradually transitions from deep red/orange to bright daylight
• 🎯 Flexible targeting - Select individual lights, multiple entities, entire areas, devices, or labels
• ⏱️ Customizable duration - Set sunrise length from 5 to 120 minutes
• 💡 Adjustable brightness - Set maximum brightness as a percentage (1-100%)
• 🎨 Color temperature progression - Smoothly transitions from 2000K (warm) to 5500K (cool daylight)
• 📅 Day-of-week filtering - Run only on specific days (e.g., weekdays only, skip weekends)
• ⚙️ Device-specific tuning - Configure step interval for smooth transitions based on your light type
• 🔧 Custom actions - Add pre-sunrise setup actions or post-sunrise cleanup actions

When creating an automation from this blueprint, you'll configure:

1. Go to Settings → Automations & Scenes → Automations
2. Click Create Automation → Sunrise Light Simulator
3. Configure:
   • Lights: Select your bedroom lights or bedroom area
   • Start Time: 06:45:00
   • Duration: 45 minutes
   • Maximum Brightness: 80%
4. Save the automation

Your lights will now gradually wake you up with a natural sunrise simulation every morning!

The blueprint uses a smooth, non-linear curve to simulate a natural sunrise:

• Color temperature: Progresses from warm (2000K) to cool daylight (5500K)
• Brightness curve: Uses a non-linear progression (power of 1.3) for natural-feeling transitions
• Smooth transitions: Updates brightness at configurable intervals (default 30 seconds)
• Hardware aware: Adjustable step interval and startup brightness for different light types
• Smart light monitoring: Stops if the light is turned off during the simulation
• Flexible scheduling: Run daily or only on specific days of the week

The algorithm starts at your configured startup brightness and smoothly increases to maximum brightness over the duration, while simultaneously shifting color temperature from warm to cool.

• Home Assistant 2021.3 or newer
• Lights that support:
  • Brightness control
  • Color temperature (Kelvin) control

Lights don't support color temperature:

• The automation will still work for brightness, but color changes may be ignored
• Consider using RGB lights or lights with tunable white capability

Automation doesn't trigger:

• Check that the start time is set correctly
• Verify the automation is enabled
• Check Home Assistant logs for errors

Transitions aren't smooth:

• Some lights have limitations on transition duration
• Try adjusting the duration to be longer
• Adjust Step Interval based on your light type (see configuration table)

Lights flicker or don't respond at startup:

• Increase Startup Brightness to 5-10% instead of the default 1%
• This helps with lights like Govee that have issues with very low commands

Automation doesn't run on certain days:

• Check that Days of Week is configured correctly
• Leave it empty to run every day
• Make sure you've selected the correct days (Monday-Sunday)
