"friendly name" will be skipped in notification

[thorny wind]

Hello.
I'm fairly new to Home Assistant and have a question about the friendly name in a notification. I would like to output the name using a condition.
The condition checks if any door in my group has the state "open". Right now, Alexa just skip the "friendly name".

action: notify.alexa_media_kuche metadata: {} data: message: >- <prosody volume="x-loud">One door ist still open</prosody> {{friendly_name }}

friendly_name of what? That is an attribute of an entity and you're currently only outputting an undefined variable

Thank you Rob. Got it.
I just have no clue how to read all entities of a group which state "on" to put the entity.name in a variable.
Maybe its just to tricky for me to do it.
