Description:
The current energy-devices-graph
card in the Energy Dashboard provides a great overview of individual energy consumption per device using bar charts with different colors. However, I would like to extend this functionality by introducing segments within each bar to show a breakdown of the energy sources contributing to each device’s total consumption.
Proposed Functionality:
For each device in the energy-devices-graph
, the bar should be segmented to represent the following categories:
-
Direct PV Consumption: The amount of energy consumed directly from solar production. (e.g. with green color)
-
Battery Discharge Contribution: The energy provided from the battery. (e.g. with yellow color)
-
Grid Consumption: The energy drawn from the grid. (e.g. with red color)
Each segment should be color-coded within the existing bar, while the device-specific color (currently used) could remain as a border or background for consistency.
Benefits:
- Provides deeper insights into energy usage patterns.
- Highlights the efficiency of self-consumption and battery usage.
- Enhances decision-making for optimizing energy utilization.
Example Use Case:
A user with PV panels, a battery storage system, and multiple energy-consuming devices wants to visualize how much energy each device draws from the PV system, battery, or the grid. For example to show in Graph:
- Device A: 30 kWh PV, 20 kWh Battery, 50 kWh Grid
- Device B: …
Additional Considerations:
- The segmentation logic would rely on existing energy sensors in Home Assistant.
- Support for tooltips or legends to clarify segment details.
I believe this feature would significantly enhance the usability and analytical capabilities of the Energy Dashboard in Home Assistant.
