# Derived template sensors for the 2× LVX6048 parallel stack.
# Each LVX6048 reports its own AC output and MPPT contribution; PI18 GS has
# no system-total field (PGS does, but powermon doesn't poll it). These
# rollups synthesize the household-level numbers from the per-unit data.
#
# Include into configuration.yaml as:
#     template: !include lvx6048/template_sensors.yaml
#
# Stack rollups created:
#   sensor.lvx6048_stack_ac_output_apparent_power  VA  (unit_1 + unit_2)
#   sensor.lvx6048_stack_ac_output_active_power    W   (unit_1 + unit_2)
#   sensor.lvx6048_stack_mppt1_input_power         W   (solar in, both units)
#
# Background: with the inverters in 120/240 split-phase wiring, an EV
# pulling 24 A at 240 V drives 24 A through each leg, so each LVX shows
# only its 120 V × 24 A ≈ 2880 VA contribution. The stack rollup is the
# real household-level number.
