Allow the use of variables in a custom text notification to tell which sensor triggered an automation. For example:

When triggered

-sensor1

-sensor2

-sensor3

Then

-sound hub

-send notification: Event is triggered by $sensor_name

Resulting in a text saying: Event is triggered by sensor3

The only way around this is to make several automation for every event that requires a different text and make a shortcut to enable/disable all those automations. Which could simply be one automation with different OR-triggers and an adaptive message.
