Earth Notes: Eddi Solar PV Diverter Top-up Dataset
Updated 2022-06-27.Various stats are gathered from the eddi (via the Internet-based API), including:
- a regular 10-minute full stats snapshot
- a per-minute record of reducing grid load in response to low grid frequency
- a summary by day of energy delivered to the heat battery by diversion from PV or boost from grid

Heat-battery target and eddi state:

Current/Recent
Current Month Eddi/Thermino kWh
2022-06: days=26.5, heat battery mean kWh/d=3.5 (divert/d=3.5, boost/d=0.0).
Recent Month Eddi/Thermino kWh
2022-05: days=31.0, heat battery mean kWh/d=4.1 (divert/d=3.9, boost/d=0.1).
Recent month's daily inputs to the heat battery by divert from PV, and boost from grid:

2022-04-18: Reading Bias
While PV is producing, and at other times when the Enphase ACB is carrying load and balancing grid flow to close to zero, the eddi reports up to ~90W import. Standing watching the LED indicators on the import and export supply meters at ~9am today, they indicated slight export (or nothing) while the eddi display was showing intermittent imports of up to ~200W. So far I trust trust the accuracy of the eddi least out of the Enphase and the supply meters. Which is not to say that the eddi is horrible!
