Since the grid meter will balance the amount imported and exported on the two phases, the net result is zero. The Envoy multiphase consumption CTs, however, will report the amounts on both phases, resulting in too high export on one and too high import on the other. One may consider using the `lifetime balanced net energy consumption` which is the sum of grid import and export to eliminate this effect. This would require some templating to split these values into import and export values. Alternatively, use the `current net power consumption` or `balanced net power consumption` with a Riemann integral sum helper. ## Envoy authentication requirements
