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.

The `powerwall` integration allows you to integrate your [Tesla Powerwall](https://www.tesla.com/powerwall) into Home Assistant.
|
|
|
|
There is currently support for the following device types within Home Assistant:
|
|
|
|
- [Binary sensor](#binary-sensor)
|
|
- [Sensor](#sensor)
|
|
- [Switch](#switch)
|
|
|

|
### 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)
|
|
|
