The table on the left shows the Events that are currently defined in my HA System. With the Buttons to the right of each EVent i can switch each event
to enabled, disabled and i can trigger them manual.
This can be usefull, for instance when i am expecting a new package to arrive i can switch on the Event that sends me an SMS in case the doorbell rings. That way i can check if someone is at home to open the door.
Because if the door isn't opened, i know i don't have to hurry home to unpack the new goodies :-)
Ofcourse i don't want to be SMS-ed every time the doorbell rings, so after the new goodies have arrived, i can switch this specific Event off
again.
