Hi,
I’m just discovering HA and I’m trying to make an automation that sends a notification to my mobile HA app, when an event occurs:
The event is like this (copied from the site from the integration maker):
I would like to put the plate (e.g. “kbw468a”, from data:plate in the json) into the message of the notify service, but I do not know how to start 
Can someone please give me a hint 
Thank you.
I want to do exactly this but didn’t find the link to Automation Trigger Variables helpful. Did you come up with a solution?
ran across this in looking for something else. it’s very old and i hope the op figured it out. but in the interest of helping someone else who runs across this…
use:
{{ trigger.event.data.plate }}
if you’re doing this for debugging purposes, i find it useful to do {{ trigger.event.data }} and get the whole array.
