It features \u003cstrong\u003eOver-the-Air Firmware Updates (FUOTA)\u003c\/strong\u003e and is equipped with a status\/alarm LED for field diagnostics. When harvesting power from Phase A, the unit requires a minimum reporting current (30A at 1min intervals or 19A at 10min intervals). For lower current measurement or initial configuration, the device can be powered via its \u003cstrong\u003eUSB Type-C port\u003c\/strong\u003e.
