Wallbox not compatible – what to do?

Updated

If your Wallbox is not supported by us, it cannot be controlled directly.
This applies, for example, to functions such as automatic charging based on electricity prices, PV surplus charging, or charging planner.

Is there still a way to control it?

Yes – in many cases you can integrate the vehicle directly instead of the Wallbox.

Vehicle Integration

Depending on the manufacturer, the following functions are possible:

  • Tesla
    → Dynamic adjustment of charging power (e.g., for PV surplus charging)
  • Other manufacturers (e.g., BMW, VW, etc.)
    → Starting and stopping the charging process possible
    → No finer power control

👉 Important: The range of functions always depends on the vehicle and the respective interface.

What else can you do?

You have two more options:

1. Test the connection yourself (OCPP – Beta)

If your Wallbox supports OCPP, you can try to connect it yourself.

Important:

  • no support
  • function not guaranteed
  • possible instability

👉 Recommended only for technically experienced users.

2. Change hardware (recommended)

For reliable use, we recommend a supported Wallbox.

Proven models:

  • easee (all models)
  • go-e Charger (all models)

With these, the following work:

  • automatic control
  • stable connection
  • optimized charging (e.g., PV surplus)

Limitation: Modbus is not supported

Wallboxes that are controlled only via Modbus (RTU or TCP) are not compatible.

Only the following are supported:

  • OCPP (limited / Beta)
  • direct API integrations

Conclusion

  • ❌ Unsupported Wallbox = no direct control
  • ⚡ Vehicle integration can be an alternative
  • ❌ Modbus = not compatible
  • ⚠️ OCPP = use at your own risk (Beta, no support)
  • ✅ For reliable operation, changing the Wallbox is recommended
