How to loop thru light effects?

Configuration
1

I am new to HA and can’t figure out how to automate this thing. I copied some holiday light code from youtube which integrated well with HA. The light has multiple effects and I want to loop thru those say every 15 mins. Tried automation and scripts but nothing worked as expected. I am able to turn on the light but it always turn on to the last effect it had. Below is the configuration.yaml config for the light. Would appreciate any help you can provide. TIA!

I did it from my cell phone last night hoping it would be in correct format. Here is the actual entry from configuration.yaml. There is also the automation at the end I tried which was able to turn on the light but was never able to set the effect.

I was hoping to see a solution for this question. Did you make any progress? Thanks!

See here: https://www.home-assistant.io/integrations/light

Call service light.turn_on with the effect you want.

There’s just a hint that you could set an effect if switching the light on, however there’s no code example for how to cycle through the effect list. I tried the same and fail as soon I reach the “None” entry in the list. No problem setting “None” directly, but programatically leads to an exception. Maybe a bug in Jinja2?
