Beta build for the grid export bug family (#253, #254, #278). Please report your results in the linked issues.
Fixed: export suppressed by a mis-scoped live power sensor. The optional live power sensor in the HA Energy grid settings (Standard mode) is expected to be signed (negative while exporting). Some integrations only offer an import-only sensor there; with such a sensor the card could never show an export. Helios now audits that sensor against your billing meters and, once the mismatch is proven (a few hours of real export are enough), reads the export from the meters instead. Correctly wired sensors are untouched, and the audit un-flags itself if the sensor is fixed later.
New: near-real-time readings from cumulative meters. When a kWh counter updates every few seconds, its live slope now drives the import/export chips instead of waiting for the recorder's 5-minute buckets.
Fixed: house consumption inflated by mixed data freshness. The home balance is now computed over a single shared time window whenever any of its inputs is bucket-based, shown with a "≈" prefix. This removes the "house absorbs the exported power" symptom.
