-Conditions are an optional part of an automation rule and be used to prevent an action from happening when triggered. Conditions look very similar to triggers but are very different. A trigger will look at events happening in the system while a condition only looks at how the system looks right now. A trigger can observe that a switch is being turned on. A condition can only see if a switch is currently on or off.

 The available conditions for an automation are the same as for the script syntax. So see that page for a [full list of available conditions][script-condition].
