How was your issue detected?:
I have two Sense units, one configured with the mains CTs on my 400A main and another pair on my solar backfeed breaker (Normal Unit) and another that has a CTs on the each of my two 200A sub panels (Dual Unit). The Dual unit is picking up one more event than the Normal Unit - The Normal Unit seems to miss a dip on L2.
