Returns the most recent real-time snapshot for a single asset. The response shape depends on assetType: batteries include state of charge, state of health where reported, available energy in kWh, and a charging/discharging/idle state; generators include run state and fuel level where reported. All asset types include online status, control mode, current output, and the location power flow (grid, load, and battery flows in kW). Use this endpoint to drive live asset tiles and pre-dispatch checks.
