I got two HEM’s, one on backed up loads and other on non backed up loads. The backed up loads only has two 240v circuits (EVSE and heater) and a Neurio energy meter. All 240v circuits and L1 and L2 are not equal. Off considerably; clamp one 13.3 kWh, and clamp two 35 kWh. Clamp one and two always have equal power. I have No explanation other than some setting got flipped
Perhaps factory reset.
