Update powerwall.markdown description (#31604)
Updated to better reflect the differences between the Powerwall Gateway device sensors and the Powerwall Battery devices and sensors.

Removed % charge description for each Powerwall battery device as this integration no longer provides that sensor (it was a calculated sensor).

Updated consistent descriptions for Power and Energy entities, including explanation of negative values.

integration

The powerwall integration allows you to integrate your Tesla Powerwall into Home Assistant.

There is currently support for the following device types within Home Assistant:

{% include integrations/config_flow.md %}

Binary sensor

The following binary sensors are added for each Backup Gateway:

  • Grid Services - On/ Off
  • Grid Status - On/ Off
  • Powerwall Charging - Charging/ Not Charging
  • Powerwall Connected to Tesla - Connected / Not Connected
  • Powerwall Status - On/ Off

Sensor

The following sensors are added for each Backup Gateway aggregated across all Powerwalls:

  • Powerwall Backup Reserve - Reserve energy for grid outages in %
  • Powerwall Battery Now - Power in kW (negative for charging)
  • Powerwall Charge - Percent charge remaining in %
  • Powerwall Generator Now - Power in kW (if applicable)
  • Powerwall Load Now - Power in kW
  • Powerwall Solar Now - Power in kW (if applicable)
  • Powerwall Site Now - Power in kW (negative for grid export)
  • Powerwall Backup Reserve - Percentage of battery which will be reserved for a grid outage
  • Frequency/ Average Current/ Average Voltage Now - in Hertz, Amps and Volts

The following sensors measure lifetime energy flow:

  • Powerwall Solar Export - Solar energy exported in kWh
  • Powerwall Solar Import - Solar energy imported in kWh (generally near zero)
  • Powerwall Site Export - Site energy exported in kWh
  • Powerwall Site Import - Site energy imported in kWh
  • Powerwall Battery Export - Battery energy exported in kWh
  • Powerwall Battery Import - Battery energy imported in kWh
  • Powerwall Load Export - Load energy exported in kWh (generally zero)
  • Powerwall Load Import - Load energy imported in kWh
  • Powerwall Generator Export - Generator energy exported in kWh
  • Powerwall Generator Import - Generator energy imported in kWh

A Powerwall battery device for each battery, connected to the Powerwall Gateway, with the following sensors:

  • Powerwall Battery Capacity - Energy in kWh
  • Powerwall Battery Remaining - Remaining energy in kWh
  • Frequency/ Average Current/ Average Voltage Now in Hertz, Amps and Volts
  • Powerwall Battery Power - Battery power in kW (negative for charging)
  • Powerwall Battery Export - Battery energy exported in kWh
  • Powerwall Battery Import - Battery energy imported in kWh
  • Powerwall Grid State - Battery grid compliance

Switch

The following switch is added for the Powerwall Backup Gateway:

  • Off-Grid operation - Take your Powerwall off-grid (simulate a grid outage)
