[SOLVED] High humidity notification with room name in the message

I’m trying to create an automation that notifies me if the humidity is too high in a room. I want to include the room name in the message, but cannot seem to get it to work.

I get the following error in the tracelog: Error rendering data template: UndefinedError 'dict object' has no attribute 'numeric_state'

EDIT: solved with {{ area_name(trigger.entity_id) }}

alias: High Humidity Notification
