Hello everyone,
I need your help please. So far I've created a flow that sends me a pushover message when my washing machine is done. Now I still have a Hue lamp in the living room and I want it to flash blue 10 times as soon as my machine is finished. After that, the lamp should return to the previous state. Unfortunately I have no idea how to do that. I have inserted my already existing flow here.

Hue lamps have a built-in alert effect. You can choose color and duration and will go back to the state before after execution.
