Color change every x minutes

You have to use a mathematical variable which is added up by 1 each time it is switched on or off. In the last flow the variable must then be set to the start number again, e.g. to 1.

In the german forum I created such flows for changing radio stations.
For translating (if necessary) you can use e.g. deepl.com. If you don’t get along with it, just let me know.

For Info: When changing color of lamps it is probably that the last set color is visible for a short time before the new color becomes active. As far as I know, changing the color (or other settings) in the background (when the lamp is off) is not possible.
