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.
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
Method 2 - the harder way
Charge HQ will now connect to your Tesla account and will display your vehicle(s) and Powerwall if present.
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.
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.
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.
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.
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.
The recommended configuration for Tesla vehicles with Charge HQ is to ensure NO charging is initiated by the vehicle. It is preferred that the Charge HQ app is used for initiation of all charging. Having both Charge HQ and the vehicle attempting to initiate charging has the potential to create conflicts. In addition, the solar tracking feature of Charge HQ can confuse the departure calculations in the vehicle.
To configure your Tesla to not initiate charging, from the Tesla App:
Select the Schedule menu
In the Schedule -> Departure tab set:
You can also confirm or apply the same settings directly in the vehicle.
In the Schedule -> Charge tab, and set
Remember: do not try to add your Tesla charger to Charge HQ!
Note: Tesla does not support or endorse third-party access to its API. Tesla may break or disable such access at any time. If this happens, Charge HQ will no longer support controlling charging via a Tesla vehicle and a smart charger (OCPP-compliant) would be required.
