Events

The Events tab lets you visualise and explore the raw event data received from the household's connected devices. It combines an interactive time-series graph with a configurable event selector, making it useful for debugging data ingestion issues, verifying sensor readings, and understanding a household's energy profile at a glance.

Event Graph

The main area of the tab displays a time-series line chart that plots the selected event types over the date range configured in the page header.

• Y-axis — Values in Watts (W). The scale adjusts automatically to fit the data and can include negative values (e.g., when power is fed back into the grid).

• X-axis — Timestamps covering the selected date range.

• Series — Each selected event type is rendered as a separate coloured line. The legend above the chart shows the event name, source type (e.g., GATEWAY), and the device identifier for each series.

• Pagination — When more series are selected than can be displayed in the legend at once, use the arrow controls (e.g., 1/2) in the top-right corner to page through the legend entries.

Common event types plotted on the graph include:

Event Type	Description
PowerConsumption	Total power consumed by the household at each measurement interval.
PowerGeneration	Power produced by the household's energy generation system (e.g., solar panels).
PowerExcess	Surplus power available after self-consumption — typically fed into the grid.
GridPowerConsumption	Power drawn from the grid (i.e., consumption minus self-consumed generation).

Event Selection

Below the graph, the Event Selection panel lets you choose which data points are displayed on the chart. The panel heading reads "Select the data points to be displayed".

Active Event Types

A table lists the event types currently plotted on the graph:

Column	Description
Type	The event type identifier (e.g., GRID_POWER_CONSUMPTION, POWER_CONSUMPTION, POWER_EXCESS, POWER_GENERATION).
Source	The source system that produced the events (e.g., GATEWAY).
Action	A remove button (✕) to remove the event type from the graph.

Adding Event Types

At the bottom of the panel, two dropdown menus allow you to add additional event types to the graph:

• Event Type — Select from the available event types for this household.

• Source Type — Select the source system (e.g., GATEWAY).

Click the + button to add the selected combination to the graph. The chart updates immediately to include the new data series.
