Some work is required in this upgrade see below. Only entities are allowed now, don’t update if you would like to still use areas and devices or make a copy of the code to use in another custom blueprint file.
Upgrade Features 
-
Light Control:
- We have now added a option to set the colour temperature of a light.
- We have now added a option to set the transition of a light and scene.
-
Sun Option: You now have the option to set a rising and falling sun elevation.
Maintenance 
- Set blueprint to my new layout.
- Clean up some descriptions.
STEPS REQUIRED WHEN UPGRADING 
-
Just need to clean up some YAML. Once you update and you see nothing selected in light control as shown below then jump to step 2.
If you see brightness selected as shown below then you are all good and don’t need to do anything hear unless you use the sun option as a trigger then jump to step 5.
-
Click on the 3 dots and select edit in YAML.
-
We are looking for the line ‘include_light_control: dont_use_brightness’. If you don’t see it then you are all good nothing more to do if you see it go to step 4.
-
Delete the line ‘include_light_control: dont_use_brightness’, click save then the 3 dots and select ‘Edit in visual editor’. If you need to make any changes do so, if you use the sun option as a trigger then go to step 5.
-
Scroll down to the sun option. You will see you have 2 inputs now called ‘Sun Elevation Falling’ and ‘Sun Elevation Rising’. Adjust to your liking.
