Print name of triggered device, alarmo

So I use alarmo to deal with security. How do I make it print the name of the device that triggers the alarm in the alert. I tried {{trigger.to_state.attributes.friendly_name}} but it says the trigger isn’t defined… not sure where to go from here.

like that :

Alarm triggered by ({{open_sensors}})

Do I need to use ({{ or just {{
?

i use ({{, try both

Can I do it for closed sensors too? Jw.

So for open it says “some example sensor is open”, does home assistant come with an example sensor open or something?

I don’t see anything with the word example in the name under entities
