This page contains instructions for configuring
chargers with Charge HQ
Please refer to our
charger listing for details on supported models and charger specifications.

Models and Firmware

The following models and firmware versions have been tested with Charge HQ:

  • Wallbox Pulsar Max, firmware 5.15.7 and higher

Any other recent firmware version should work. Wallbox chargers often update themselves to the most recent firmware.

Step 1 - Obtain an EVSE ID from Charge HQ

  • Open the Charge HQ app
  • Go to Settings tab -> My Equipment -> Connect your Smart Charger
  • EVSE ID: this will be entered into your smart wall charger, note down that value displayed on your app or copy it to the clipboard. You will use this in Step 3.
  • Min and Max Power (A): Update these if you believe they are different to the default settings. For both single and 3 phase chargers, these values are defined per phase.
  • Click Submit

Note: The EVSE ID is a unique identifier for your charger, it cannot be the same as any other OCPP charger that is connected to Charge HQ. For this reason Charge HQ will provide you with a known-unique value that you can set in your charger.

Step 2 - Connect charger to WiFi and open app

Install the Wallbox app on your phone (available on the app stores) and follow the prompts to connect to your charger. This is usually done via Bluetooth.

The charger must be configured to connect to your home WiFi network as it requires internet access.

Step 3 - Configure OCPP in the Wallbox app

Select OCPP settings

In the OCPP settings, configure:

  • URL: ws://ocpp.chargehq.net/ocpp16
  • Charge point identify: <as obtained from the Charge HQ app in Step 1>.
  • Password: <blank>
  • Tick the Terms and Conditions
  • Click SAVE

The charger should connect to Charge HQ within a minute or so. A reboot should not be required, but may be worth trying if the charger is not connecting.

Note: if you prefer to connect via SSL, please refer to our SSL connection guide.

Step 4 - Ensure Eco-Smart mode is disabled

Charge HQ cannot be used in combination with Eco-smart modes on the Wallbox charger. Please ensure they're disabled via:

  • Open the wallbox app
  • Under Settings select Upgrades
  • Set the Eco-Smart feature to Off

Step 5 - Confirm communication with Charge HQ

Lastly - confirm that the charger is connected to Charge HQ.

In the Charge HQ app, navigate to Settings → My Equipment → Smart Charger

Confirm that the Connection State reads “Online”

Step 6 - Confirm ability to control charging

  • From the home screen of the Charge HQ app, select “Charge Now”
  • Confirm that the LED lights on the charger and the display on your EV indicate the vehicle is charging.
  • Confirm that charging is occurring at the configured rate (Amps)
  • From the home screen of the Charge HQ app, select “Stop”
  • Confirm that charging of your EV has stopped.

Step 7 - Continue Charge HQ configuration

Charge HQ can now control your Wallbox EV charger.

See our Step by Step setup and other app configuration guides for assistance with configuration of the rest of the Charge HQ app.


From time to time Wallbox chargers may stop responding to commands from Charge HQ. We believe this is a due to a firmware bug. In such cases both automatic solar charging and manual charging control will stop working. To resolve:

  • Unplug the charger from the vehicle
  • Power down the Wallbox charger
  • Wait 5 minutes (really)
  • Power up the charger

Known Issues

Charging restarts after STOP mode selected

This issue impacts older firmware versions, including 5.11.14. It does not impact recent versions. If you experience this issue, please update your charger's firmware using the Wallbox app.

The STOP function, activated manually in Charge HQ, does not work with older firmware versions. The charging will stop and will then restart immediately and the charge mode will return to AUTO.

For troubleshooting instructions see the OCPP charger configuration guide.
