Returns every NeuraCharge-managed asset at the specified IESO BTM location. Each asset includes its type, make and model, rated power in kW, storage capacity in kWh where it applies, current state of charge, current output in kW, online/offline status, and current control mode. Fields that do not apply to an asset type (for example, capacityKwh and socPercent for a generator) are returned as null. Use this endpoint to build an asset inventory or the asset list on a location overview.
