+# Today's solar harvested + household energy used — daily-resetting kWh
+# sensors for a dashboard indicator.
+#
+# This is a Home Assistant *package* (bundles several domains in one file)
+# so the whole feature installs as one unit.
+#
+# Install:
+#   1. Copy to  <config>/lvx6048/daily_energy_package.yaml
+#   2. In configuration.yaml (once), pull it in as a package:
+#        homeassistant:
+#          packages:
+#            lvx6048_daily_energy: !include lvx6048/daily_energy_package.yaml
+#   3. Requires template_sensors.yaml already loaded (provides
+#      sensor.lvx6048_stack_ac_output_active_power).
+#   4. Restart HA.
+#
+# Produces two dashboard-ready entities:
+#   sensor.solar_harvested_today   kWh  — PV generated today (both inverters)
+#   sensor.solar_used_today        kWh  — household load consumed today
+#
+# Data sources & why:
+#   - Harvested: each inverter exposes a *lifetime* Wh counter
+#     (total_pv_generated_energy); the LVX6048 firmware has no daily-energy
+#     query (ED is NAKed). A daily utility_meter on the lifetime counter gives
+#     today's harvest from the inverter's own internal accumulator (accurate).
+#   - Used: no cumulative load counter exists, so the household load *power*
+#     (sensor.lvx6048_stack_ac_output_active_power, sum of both inverters'
+#     AC output from template_sensors.yaml) is Riemann-integrated into energy
+#     and metered daily. This is an estimate; accuracy tracks powermon's GS
+#     poll cadence. Counts only load served by the inverters.
+#
+# NOTE: verify the two source entity_ids match your HA install
+#   (Developer Tools -> States): sensor.lvx6048_1_total_pv_generated_energy
+#   and sensor.lvx6048_2_total_pv_generated_energy.
