List standalone HEMS steering sessions for a wallbox
One row per charging session the wallbox steered on its own, without a connected vehicle account, newest first, for sessions that started on a UTC day between from and to inclusive. Each row carries the rolled-up outcome, the energy taken from solar, the home battery and the grid in kWh, the savings in EUR with their attribution reason, and the counts of commands sent, applied, ineffective and rejected. A null savings figure means the provenance could not be established, not zero. The per-poll decision timeline and each command’s verdict are on the unified charging-sessions detail route under the user, addressed as wb_{id}.
