Electricity at home with solar panels on one tile, in the spirit of Home Assistant's energy dashboard.

The tile shows the sun, the house and the grid side by side: what the panels make now, what the house uses, and what comes from the grid or goes back to it. Arrows show where the power flows; a circle takes its colour while power flows there (amber for the sun, blue for power from the grid, green for power to it). Under them, when there is room:

  • a bar of the house's use, amber as far as the sun covers it, blue for the rest ("Solar covers 46 %");
  • the day so far ("Today: solar 3.4 kWh · from the grid 5.2 kWh");
  • what the panels made against today's forecast, as a bar.

It fits any size from 1 x 1 to 6 x 3: on a narrow tile it shows the grid and, under it, the sun. Each part shows only while there is room for it and a sensor for it. A tap opens a card: at the left the flow as in Home Assistant's energy card, the sun above, the grid and the house below, joined by lines that take their colour and a dot where power flows; at the right every chosen sensor in a row of its own (grid, solar, house, coverage, solar today, forecast with how much of it is made, grid today).

Set up

  1. In Tessera, open Plugins, Add with a link, and paste the link of this repository. Add the plugin to a screen.
  2. In the plugin's details on the screen's Plugins tab, under When building, choose the sensors:
    • Grid power (needed): your meter's power in W or kW, positive while power comes from the grid and negative while it goes back. A meter that counts the other way round: switch on Invert the grid on the tile.
    • Solar power: what the panels make now.
    • Solar today, Grid today: today's energy in kWh, for the day so far.
    • Solar coverage: a sensor in % if you have one; without it the share is worked out from solar and grid.
    • Forecast today: today's solar forecast in kWh (Forecast.Solar, Solcast). Leave out what you do not have. Save and build.
  3. In Layout, place the Energy tile.

Good to know

  • The house's use is grid + solar. A battery is not part of it yet.
  • W and kW, Wh and kWh are both understood: the plugin reads each sensor's unit.
