…ment 1) (#106) Add CircuitMeterImeasured and MaxCircuitMains to evse_ctx_t. Clamp IsetBalanced by subpanel circuit headroom in evse_calc_balanced_current(). 5 native tests with SbE annotations. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…4, Inc 2-3) (#107, #108) Add third Meter instance for subpanel metering. Poll via Modbus when enabled, sync to evse_ctx_t via bridge, persist settings in NVS. - meter.h: extern Meter CircuitMeter declaration - main.h: CIRCUIT_METER, CIRCUIT_METER_ADDRESS, MAX_CIRCUIT_MAINS defaults - main.cpp: CircuitMeter instantiation, MaxCircuitMains global, Modbus polling states 23 (current) and 24 (energy) in ModbusRequestLoop - modbus.cpp: route CircuitMeter responses in HandleModbusResponse - evse_bridge.cpp: sync CircuitMeter.Irms max and MaxCircuitMains to ctx - esp32.cpp: NVS read/write with settings cache for 3 new keys Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
#109) Publish circuit current/power/energy via MQTT with HA auto-discovery. Add Set/MaxCircuitMains and Set/CircuitMeter topics. REST /settings integration for circuit meter configuration. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…ment 5) (#110) Add circuit_energy_wh to session_record_t. When CircuitMeter is active, session JSON includes circuit_kwh field for ERE compliance verification. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
