| Please find below the various piece of code that together control my RGB light to loop in Rainbow. | |
| Every two seconds, it change from one colour to another based on the value of the second. | |
| So it compute 30 differents RGB value in a "circle", all with the same Saturation and Brightness both forced to 1.0 | |
| The transition from one colour to another is done in one seconds. | |
| The name of my Tradfri RGB light bulb is "light.couleur" | |

| Source code for the Hue based RGB computation from last post of this: | |
| https://community.home-assistant.io/t/hue-random-color-autiomation-help/52122/10 | |
| PS: I am totally not a Home Assistant expert, so there might be better way to implement this. | |
| Fell free to comment or propose better way to control that. | |
| Such as verifying if the light is on (as a condition) before changing the RGB colour. | |
| Anything really, today I just want it to work, but I am ready to learn. |

My son can come out of bed when the light is green. when the light is red or orange, it is to early to wake up. How do I make such an automation ? And is it possible to enter a "time" when it has to be green ?
so setting the time at 07.00 ( not hard coded) ; starting at 06:40 with red for 10 minutes, 06:50 orange for 10 minutes and than at 07:00 half an our or so green ?
Hi I'm trying to achieve change of colour every 5 minutes with smooth transition of colours.
I cannot figure out function if with modulo. I got this but it only works every 5 seconds set in automation. Any other automation timing results in skipping colours.

@Gavergracht : your question is out of the scope of this gist. I suggest you to ask directly on the forum of home-assistant :)
@willyfog78 : you should change the timer to execute it every 5min and in the script, change the condition by something like now().minute % 5 == 1
@loic-moriame I took your work and created a Home Assistant Blueprint from it (I credited you), I hope it's ok.

@hugalafutro: this is definitely in the spirit of open source and knowledge sharing.
I more than agree with that 👍

Sure!
For transition, just change the value of
transitionparameterIf you want more colors, just change the modulo value (3 to 6 for example) and add more conditions
Let me know if you want some help
P.S: I try to use an array for RGB colors but without success, that why I switch to multiple conditions inside the script
