Creating scenes

Can someone please tell me which config file I can create a scene in? Does it go in the automations.yaml file?

Can I scene be reused in multiple automations?

Confused.

Thanks

You can make a scenes.yaml file and include it the the usual way. A scene is basically a list of switches/lights to turn on/off, so yes you can use them as many times as you want.

Thanks for the quick reply.
