# Set Operation

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

<div align="left"><img src="/files/2gPag50PeW1RIGMaj47r" alt="" width="300"></div>

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

{% hint style="info" %}
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.
{% endhint %}
