It would be nice to be able to link 2 SENSE units that are in the same home. I have a 400 Amp service to the house which is distributed between two, 200 Amp breaker panels. I have 2 SENSE units installed - each with its unique email / login. I have to log off one account and then log in to the other account in order to see all my devices. I imagine that this would make it more difficult for SENSE to discover my devices as, for example, I have my washing machines connected to one breaker panel and the dryers on the other.
