Automation - save current LED setting and reuse them at the end

Configuration
1

Hello all,

I’m still quite new with the HomeAssistant and get by with the many help here in the forum very well. Only sometimes you do not find exactly the topic where I need help. Therefore here a new topic :wink:

I have a LED strip in my smart home. In some automations I let the LED strip light up in a certain color. This is visual information for me, which is very important.

What I am missing now: I would like that the LED strip is set again after the automation as it was:

These values are decisive:
state: ON
brightness: 12
color_mode: xy
color: x: 0.4066, y: 0.1643
color_temp: 153

How can I read these values in an automation and save them temporarily so that I can use them again later in the same automation?

Greetings,
Ulrich

I use the scene create service to take a snapshot before I do stuff and then call it when I’m done to put things back they were before.

Yes - the “scene.create” and the “scene.turn_on” was the missing knowlegde at my side :wink:
