Is there any way to send alert when the current power hits some point? for example I have hire 100K of MaX Current Power, and hits over it I pay a fine, so I would like to be notify when it gets to 90K, is it possible? even if I have to use it on Home Assistant.

Yes, 

IAMMETER cloud has such functions, it can push the alert by email, if the power or current value is greater than the threshold.
