Connect Charge Amps with LadeKosten

How the integration works

Charge Amps chargers connect to the internet via your home WiFi or Ethernet, syncing all session data to the Charge Amps Cloud. LadeKosten accesses this data through the official cloud API using a combination of OAuth2 authentication and an API key.

The OAuth2 layer handles your identity verification securely, while the API key provides an additional layer of access control. This dual-authentication approach is a sign of Charge Amps' enterprise-grade security mindset, and LadeKosten works seamlessly within it.

Once authenticated, LadeKosten reads your session history including energy consumed, session duration, timestamps, and charger identification. The app applies your electricity rate to calculate per-session costs and aggregates the data into useful overviews.

Because this is a cloud integration, your data is accessible from anywhere. You do not need to be on your home WiFi to check your charging costs or generate reports.

Supported models

Charge Amps offers three charger models, all of which will be supported:

• Charge Amps Halo - The flagship residential charger with its iconic circular design. Up to 22 kW charging power, built-in energy meter, and WiFi/Ethernet connectivity. Full session tracking in LadeKosten.
• Charge Amps Aura - The commercial and semi-public charger designed for workplaces, hotels, and multi-unit buildings. Supports RFID authentication and multiple simultaneous users. LadeKosten tracks your individual sessions.
• Charge Amps Dawn - The compact, cost-effective option for simple residential installations. Same cloud connectivity and same LadeKosten compatibility as the premium models.

All three models connect to the Charge Amps Cloud platform, so the integration works identically across the range.

Setting up Charge Amps with LadeKosten

Open LadeKosten and go to the wallbox setup. Select Charge Amps from the list of supported brands. You will be guided through the OAuth2 authentication flow, which involves signing in with your Charge Amps Cloud account.

After authentication, LadeKosten fetches your registered chargers. Select the one you want to track. If you have multiple chargers, you can add them all and track each separately.

Set your electricity price per kWh, and the app immediately calculates costs for your synced session history. Going forward, new sessions appear automatically as they are completed.

The entire process takes about three minutes. Authentication tokens are managed automatically, so you should not need to sign in again unless you explicitly disconnect the integration.
