+# power_integral_sensors.yaml
+# Integral energy sensors derived from the existing 3-phase active power sensors.
+#
+# Assumption:
+# - Source sensors are reporting active power in watts (W).
+# - These integrals therefore convert W over time into kWh.
+#
+# Notes:
+# - method: trapezoidal gives smoother and generally more accurate integration.
+# - round: 2 gives a displayed precision of 0.00.
+# - unit_time: h with unit_prefix: k gives kWh output from watt-based inputs.
