Greener – Alfen battery container

Configuration steps​

  1. API credentials

    • Retrieve the API key and Battery ID in the Greener portal.
    • They are required by the driver’s “User Inputs”.

  2. Add the device

    • In Integrations → Add device choose Greener API for Alfen Battery Control.
    • Enter the API key and Battery ID exactly as provided.
    • Confirm → the container appears with SOC and power.

  3. Optional – setpoint control
    When Smart-Grid Mode is enabled the driver sends a constant-power set-point (positive = charge, negative = discharge) to
    /control/batteries/<ID>/command/set_constant_power_setpoint.

Troubleshooting​

  • 401 Unauthorized – check the API key string (no spaces, full length).
  • 404 on Battery ID – verify the exact GREENER_XXX identifier.
  • Power not updating – Greener API provides new datapoints every ~10 s;
    ensure outbound HTTPS (443) traffic is allowed.
