SDM630 Test Flow
Based on biancode modbus library with added influxdb outputs. Still in experimenting mode. Uses modbus to poll 2 x SDM630 meters and pull various measurements. Totaliser (chrismoorhouse) used to determine difference between imported and exported power going through meter #2 Most outputs to influxdb and visuals with grafana.
Happy to accept any suggestions on improving performance and streamlining.
