I went looking for some type of automation that would rotate through the list of available effects on a bulb without having to create a static list to go through. In the end I created this automation that only needs a text input helper to work. It also uses the list of effects reported back by the bulb to work through it, so it should adapt to any list of effects the entity lists as available (check in the developer panel under states).
Each bulb controlled with this automation will need a text input helper to be created with an initial value of none so the automation can read the first on the list when it starts. In the code below it is called current_wiz_effect
This automation also has two triggered inputs that can be used to move forward or backwards through the list. The forward behavior is the default, but remember to add the trigger ID to your entries if you want to use the backwards functionality.
There are a few odd choices in here like adding a backtick to the end of the effect name to flag it. This is so it doesn’t match anything else in the list, and you can’t always rely on the bulb state when you have a finicky effect. The wiz bulb in question will switch to Rhythm but then a second later switch back to the previous effect. So if you send the trigger within 15 seconds of the last one, it relies on the helper value to determine the current effect. Otherwise it reads it from the bulb to find the next on the list.
Hope this helps someone out there, I’m curious how it does with different effect lists.
