    • Here filled with default values (values that are used when the attribute is not explicitly listed)

    • username: the default ("customer") is currently the only username that will work when logging in, i.e., there is no need to change any username; using "customer" here, will just work.

    • email: is part of the login data. However, it currently seems to be ignored, i.e., it does not matter what email is entered.

    • loginInterval, pollingInterval or historyInterval in milliseconds

    • loginInterval: the login is executed periodically based on this interval. After a successful login, the authentication token is currently valid for 24h. If your internet is unreliable, it may be helpful to set a lower interval to guarantee at least one successful login in the 24h time span. The default of 39600000ms corresponds to 11h.

    • lowBattery: Percentage when the charge is considered critical/low

    • additionalServices: Services additional to the basic switch with the battery status.

      • ...Switch: Adds a switch that represents the current state. (Useful for implementing Homekit automations.)
      • ...Sensor: Adds a sensor that represents the current state. (Useful for implementing Homekit automations.)
      • powerwall.homekitVisual: Adds a lamp service representing the battery level.
      • powerwall.eveHistory: Adds an Eve weather service; sets the temperature to the battery level in percent.
      • powerwall.makeOnOffSwitchReadOnly: While the powerwall switch will still be able to be flipped within, for example, the Home.app, when this field is true, it will not have any effect. The switch is always going to update its state based on the received state.
      • Powermeter i.e. solar, grid, battery, home
        • *.homekitVisual: Adds a fan service displaying the current power in watts.
        • *.evePowerMeter: Adds an Eve powermeter service.
        • *.evehistory: Adds the total consumption to an Eve powermeter service. Only works when evePowerMeter is also set to true.
        • *.eveLineGraph: Saves power data in an Eve weather diagram to get a nice line chart.

    History Configuration

    From: Fakegato project

    No persistence (The Elgato-Eve App will still save received measurements):

    • Do not include "historySetting" in the config.json.

    File-System persistence:

                "historySetting": {

    Mandatory:

                    "storage": "fs",

    Optional:

                    "size": 4032,
                    "path": "/place/to/store/my/persistence/"
    • "size" default: 4032
    • "path" default: .homebridge folder of the user or the given homebridge -U location
                }

    Google Drive persistence:

                "historySetting": {

    Mandatory:

                    "storage": "googleDrive",

    Optional:

                    "size": 4032,
                    "folder": "fakegato",
                    "keyPath": "/place/to/store/my/keys/"
    • "size" default: 4032
    • "folder" default: "fakegato" as the folder on Google Drive.
    • "keyPath" default: .homebridge folder of the user or the given homebridge -U location
                }

    For the setup of Google Drive, please follow the Google Drive Quickstart for Node.js instructions from https://developers.google.com/drive/v3/web/quickstart/nodejs, except for these changes:

    • In Step 1-h the working directory should be the .homebridge directory
    • Skip Step 2 and 3
    • In step 4, use the quickstartGoogleDrive.js included with this module. You need to run the command from fakegato-history directory. Then just follow steps a to c.

    FAQ

    I get a login error

    If you get a login error similar to:

    [4/16/2021, 6:56:52 PM] [Powerwall] error: null
    [4/16/2021, 6:56:52 PM] [Powerwall] status code: 403
    [4/16/2021, 6:56:52 PM] [Powerwall] body: {"code":403,"error":"Unable to GET to resource","message":"User does not have adequate access rights"}
    
    • Ensure that the password is correct. Regarding the username, currently only "customer" (the default) will be accepted by the powerwall.
    • The powerwall might require a re-registration and password update.

    Plugin stopped working after the Powerwall upgraded to version 20.49.0

    Upgrade to the latest update of this plugin and make sure the password field is added (see documentation above).

    The username field should, at the moment, have a value equal to the default, i.e., it must be equal to "customer".

    Plugin behaves not as it should and the Powerwall version is lower than 20.49.0

    Try to use the last 1.x.y version "1.1.0", i.e., sudo npm install -g homebridge-tesla-powerwall@1.1.0.
