Leviton Smart Breakers
We were aware of the Leviton Smart Breakers when we built our house but they would not be available in time so were not an option (and our electrical contractor dislikes Leviton breakers based on past experience).
He did install them (78 circuits IIRC) on a job that was about 6 months behind ours. He said that the energy monitoring worked well once they got everything working but did take some phone time w/ Leviton. Initially they were much more likely to get an AFCI trip than other breakers but Leviton (with lots of phone calls) was able to alter the response curves on individual breakers to eliminate that. He said the homeowner is quite happy with them now.
FWIW, we initially had Siemens breakers. He’s replaced a bunch of them w/ Eaton due to AFCI trips so this isn’t just a Leviton problem.
