Power Flow Card
A bounded energy-flow monitor for a fixed Grid, Solar, Battery and Load topology. HARDWARE VALIDATED on the current ESP32-P4 evidence ledger.
#14 — Power Flow Card
A bounded energy-flow monitor for a fixed Grid, Solar, Battery and Load topology.
- —Grid import and export
- —Solar production
- —Battery charge and discharge
- —Load monitoring
Inspector capabilities and presentation
- —240 × 145 default and 220 × 128 minimum stackable geometry
- —Fixed Grid / Solar / Battery / Load topology
- —Static none, inward and outward flow directions
- —Text-backed node values
The component remains one serialized Canvas object. Browser Preview, Live Studio and Standalone Export consume its normalized semantic model while internal LVGL composition stays private.

No UserEvents are generated.Power Flow Card is monitoring-only. Its topology and static flow directions are bounded; it is not a generic SCADA diagram editor.
Where hooks exist, implement the exact declarations in 95_UserEvents.c. Runtime SDK calls never simulate user input.
Ownership boundary
ForgeUI owns semantic presentation, private LVGL composition, generated contracts, persisted identity, fixed storage and Browser/Live/Standalone alignment.
