# PFV plant energy helpers (kWh) for Home Assistant [#439]
#
# Paste into configuration.yaml. Riemann-sum integral: W -> kWh with the
# `integration` sensor platform (kept across restarts). Feeds the Energy
# dashboard (Settings > Dashboards > Energy > add grid/device consumption
# sources pointing at these kWh sensors).
#
# Node power comes from the ACPI power_meter read through the SNMP extend
# (see sensors-snmp-plant.yaml): sensor.pfv_tsys6_node_power /
# sensor.pfv_tsys7_node_power, in watts.
