# Set Operation

The first step is to choose the item on which the operation will be performed.

<div align="left"><img src="https://3582462918-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FmaDJsMJp40TdufW4KHYA%2Fuploads%2Fgit-blob-6f27150f21799ef5a04794662abe4bb38f5997c0%2Fandroid_set_operation_page.png?alt=media" alt="" width="300"></div>

Once the item is defined, you can click the **Choose Function** button and select the operation to execute.

If you wish to perform the operation with a delay, you can set a timer. This configuration is very useful if other operations have been set up. For example, if you want a light to stay on for 30 seconds, you can configure a first operation to turn on the light, and a second operation to turn it off after a 30-second delay.
