HEMS
Home Energy Management components for devices, power flow, and energy charts.
The HEMS (Home Energy Management System) components are the domain-specific building blocks for energy management: connected devices, live power flow, and energy-over-time charts. They build on the same tokens and primitives as the rest of Spark UI, and ship inside a HEMS, a complete Spark block embedded in an epilot customer portal.
Device Card
Summary tile for a connected device.
Feed-in Hero
Headline metric for grid feed-in / consumption.
Power Network
Live diagram of energy flow between sources.
Energy Breakdown
Split of energy by source or use.
Energy Bar Graph
Bar chart of energy over time.
Energy History Chart
Stacked energy bars for week, month, or year.
Power History Chart
Diverging area chart of instantaneous power.
Sankey Chart
Flow diagram of how energy is distributed.
Solar Forecast Chart
Predicted solar generation over a day.
Lower-level visx primitives (LineChart, BarChart, tooltip helpers) live
