Operational Heatmap

What it shows

A colour grid that shows how busy something was over time, so patterns jump out at a glance. Cool blue means low, warm red means high.

Where to find it

Open Dashboard, click the pencil in the dashboard top bar to enter edit mode, click Add New Widget, search the picker for Operational Heatmap, then click Add Widget.

Reading it

Each cell is a slice of time, coloured by how high the value was in that slice. Read across and down to see the rhythm of the site: which hours run hardest, or which days stand out.

Use the period buttons D, M and Y, with the date picker, to change the span.

A tile you have just added starts on no period at all and draws nothing. Click D, M or Y once and the grid appears.

Settings

Open the tile's settings with the spanner icon.

Title - name the widget. New tiles start as "Heatmap".
Data Series - what to colour by: Grid W import, Grid W export, Load W, PV W (the default), PV Manager (by device), PV Manager (by mppt) or PV Manager (by input).
Group By - set the columns to Hour (the default) or Day.

Tips

Group by Hour to see the daily shape of your load or solar, and by Day to compare one day against the next across a month.
