The numbers
Every figure below is pushed automatically from Home Assistant at 00:15 each night. The kWh come from the Sigenergy inverter's own meters and the costs from Predbat's daily tracking, including its estimate of what each day would have cost with no solar or battery. Nothing is typed in by hand. How the pipeline works →
Running totals
Daily generation vs consumption
Grid flows · export ↑ / import ↓

Monthly ledger
| Month | Days | Gen kWh | Export kWh | Import kWh | Net cost £ | Saved £ |
|---|---|---|---|---|---|---|
| June 2026 | 1 | 11.8 | 0.0 | 0.1 | 0.00 | 0.00 |
| All time | 1 | 11.8 | 0.0 | 0.1 | 0.00 | 0.00 |
A day's saving is Predbat's no-solar baseline (what that day's usage would have cost imported entirely at Agile rates) minus the actual net cost (import cost minus export revenue). Standing charges affect both sides equally, so they cancel out.
