# Read more: https://www.vcloudinfo.com/2018/01/going-green-to-save-some-green-in-2018.html | Issue #272
# Tesla Powerwall added via UI Integration
# --------------------------------------------------------------
# Binary Sensors:
#  - binary_sensor.powerwall_charging ............. battery_charging (on=charging)
#  - binary_sensor.powerwall_connected_to_tesla ... connectivity (on=connected)
#  - binary_sensor.powerwall_grid_services_active .. power (on=active)
#  - binary_sensor.powerwall_grid_status .......... power (on=grid up)
#  - binary_sensor.powerwall_status ............... power (on=system ok)
#
# Power & Energy Sensors:
#  - sensor.powerwall_charge ...................... battery %, 0–100
#  - sensor.powerwall_backup_reserve .............. reserve %, 0–100
#  - sensor.powerwall_battery_power ............... kW (+discharge / -charge)
#  - sensor.powerwall_load_power .................. kW house load
#  - sensor.powerwall_site_power .................. kW (+export / -import)
#  - sensor.powerwall_solar_power ................. kW solar production
#
# Lifetime kWh Meters:
#  - sensor.powerwall_battery_export .............. kWh -> grid/load
#  - sensor.powerwall_battery_import .............. kWh <- battery charged
#  - sensor.powerwall_load_export ................. kWh exported from loads
#  - sensor.powerwall_load_import ................. kWh imported to loads
#  - sensor.powerwall_site_export ................. kWh site -> grid
#  - sensor.powerwall_site_import ................. kWh site <- grid
#  - sensor.powerwall_solar_export ................ kWh solar -> site/battery/grid
#  - sensor.powerwall_solar_import ................ kWh solar <- grid (rare)
#
# Switches:
#  - switch.powerwall_off_grid_operation .......... island mode toggle
