Not too sure what you are talking about, the only esp protocol I know 
is for encryption during a vpn connection... But basically, this ups 
is so "dumb" the only connection between the pc and the ups is 
through the power cable... Unless you find a way to communicate 
through that, there is no way you can know there is a power outage 
(lol unless there is a speaker and you use a microphone to listen for 
the alarm :)
