Add sensor data to message output in node red

Hello.
I’ve been researching for several hours and I’m having a lot of troubles understand how I can add information from a sensor from HA into a message. That might be explained poorly, but the hopefully I can clear it up.

My goal is to be able to send a message over my google home when there is severe weather warnings.
I have some NOAA sensors setup correctly that will give me the information I need and when. I also have the correctly set up the google home notify.

I have (sensor.noaa_alerts_event) and (sensor.noaa_alerts_headline) in HA

I’d like a message to be sent to my google home that says
“Alert, the National Weather Service has issued a (sensor.noaa_alerts_event). (sensor.noaa_alerts_headline). Please be safe.”

I believe that I’m getting caught up in how to correctly parse that into json in node red.

I would appreciate anyone’s help

Thanks
Marshall

The data field of the call-service node.

{"message":"Alert, the National Weather Service has issued a {{entity.sensor.noaa_alerts_event}}. {{entity.sensor.noaa_alerts_headline}}. Please be safe."}

I can’t believe it’s that simple. Thank you!!! I was trying template nodes going into json converters… it was a hot mess.
