Tesla Setup

Supported Tesla Models

Model 3 & Model Y: All features work with all vehicles.

Model S & Model X: All features work with all vehicles.

NOTE: if you can't adjust the charging amps from the Tesla app you may need to update the firmware of your vehicle. If you still can't adjust the charging amps then Charge HQ won't be able to either. In this case the charging power can't be adjusted to match the available solar; starting and stopping will still work.

Connecting Your Tesla

Charge HQ connects to your vehicle using your Tesla account and controls the charging using the same mechanism that the Tesla app uses.

To connect your Tesla account:

Method 1 - the easy way

• use the Charge HQ mobile app (iOS or Android)
• tap on the menu -> My Equipment -> Connect your Tesla.
• tap Next. You will be taken to the Tesla login screen
• enter your Tesla login details

Method 2 - the harder way

• install a Tesla token app on your phone, such as:
• iOS: Auth app for Tesla
• Android: Tesla Tokens
• use the app to generate an "SSO Refresh Token", copy this token to the clipboard
• in the Charge HQ app (mobile app or web app):
• tap on the menu -> My Hardware -> Connect your Tesla.
• tap on "provide an API token"
• paste the SSO Refresh Token

Charge HQ will now connect to your Tesla account and will display your vehicle(s) and Powerwall if present.

Do Not Add Your Charger

Do not try to add your charger to Charge HQ. Charge HQ controls charging via the Tesla vehicle, not via the charger. It doesn't matter if you use the Tesla HPWC (wall charger) or UMC (mobile charger) or both, or any other charger.

If you add a Smart Charger to Charge HQ and don't actually have a smart charger, Charge HQ will no longer be able to control charging because it is waiting for the Smart Charger to connect.

Multiple Vehicles

If you have multiple vehicles visible from your Tesla account Charge HQ will allow you to select one vehicle to control. Only one vehicle can be controlled by Charge HQ at any time. You can switch between vehicles using the drop-down on the home screen.

Powerwall

If you have a Powerwall, Charge HQ will detect and configure it when you add your Tesla account. You should see your solar and Powerwall data on the home screen.

Charge HQ obtains all solar and battery data from the Powerwall. When your Powerwall is selected Charge HQ will automatically configure a Solar Data Source with Type = Powerwall. Please do not try to add your solar inverter as well.

Multiple Powerwall Sites

If your Tesla account is linked to multiple Powerwall sites, Charge HQ allows selecting the current site by navigating to My Hardware -> Tesla Account. Charge HQ currently only supports one site at once. Switching between sites must be done manually.

Tesla Solar

If you have a solar system installed by Tesla with a Gateway, or a Tesla Solar Inverter and you can see your solar production in the Tesla app, Charge HQ will detect and configure it when you add your Tesla account. You should see your solar data on the home screen.

Vehicle Configuration

Tesla vehicles have an in-built charging schedule feature. For most users, the recommended configuration is to disable the vehicle's charging schedule and use Charge HQ for all charging control, including scheduled charging (but see notes below). This helps avoid confusion caused by different systems trying to control the charging. See below for instructions on how to ensure the vehicle's charging schedule is disabled.

Despite this recommendation, if you wish to use the vehicle's charging schedule, you can. When Charge HQ detects charging that was started by the vehicle's schedule it will allow it to charge to the vehicle's charge limit.

Notes:

• Some users experience an issue where their vehicle starts charging unexpectedly at random times. The recommended configuration for those users involves enabling the vehicle's schedule and enabling the Override Vehicle Schedule option in Charge HQ. See this page for details and instructions.
• Charge HQ's solar tracking feature may impact the departure calculations if departure charging is enabled on the vehicle. Charge HQ tries to avoid this problem but it may not always work reliably.

Disabling the vehicle's charging schedule

To ensure the vehicle's charging schedule is disabled, from the Tesla app:

Step 1

Select the Schedule menu

Step 2

In the Schedule -> Departure tab set:

• "Off-Peak Charge" toggle to disabled
• The departure time can be set to anything as it will not be used
• Procondition can be enabled/disabled

You can also confirm or apply the same settings directly in the vehicle.

‍

Step 3

In the Schedule -> Charge tab, and set

• the "Enable Scheduled Charging" toggle to disabled.
• The "Start Charging at" time can be set to anything as it will not be used.
