How do I tell Cura when it reach certain level or layer to change

How do I tell Cura when it reach certain level or layer to change temperature?

Tweak a Z plugin will allow a change to a parameter at a specific Z elevation.

I saw this z plugin but wasn’t sure how to utilize it. Can anyone post sample code? Thx

Click the Plugins tab in Cura, double click on the Tweak at Z plugin and enter the Z height where you want the change and any values you want to change.

Got it. Thx all for the pointer
