Home Flow Card

Your own little isometric home

Home Flow Card draws your live power on a little house: solar on the roof, a battery on the wall and the grid running off to the street. One look tells you where your power comes from and where it goes.

Why a house?

Reads at a glance

Solar sits on the roof, the battery on the wall, the grid runs off to the street. You know where your power comes from before you read a single number.

Motion that means something

A pulse runs along every wire in the direction its power flows, faster and longer the more it carries. Numbers roll to their new value, units slide along, and the battery's word changes only the letters that change.

Made for your dashboard

Monotone greys taken from your theme, light and dark, with colour only where power flows. It scales to any card width, and the visual editor sets it up without YAML.

Ready for the bad days

When the grid fails, its cable goes dead and its label says so. An optional generator appears, wired to the inverter and never to the grid, and its label takes the grid's place. A nearly empty battery turns its bar yellow, then red.

A day on your house

The same card through the day. Each one is live; open it in the playground to make it yours.

A sunny afternoon

The roof charges the battery and sends the surplus to the grid.

An evening on the battery

The sun is low; the battery carries the home, the grid rests.

Play
A night on the grid

The battery is nearly empty: its bar turns red and the grid takes over.

Play
A grid outage

The grid cable goes dead and the generator steps in, wired to the inverter.

Set up in a minute

Point it at the sensors you already have: grid, solar, battery and, if you like, the home. Leave one out and the house simply doesn't draw it.

Already using Power Flow Card Plus?
Home Flow Card reads the same sensors and its nodes take the same options. Change the type, move grid, solar, battery and home out of entities, and your house is ready. Individual devices are not drawn yet; keep Power Flow Card Plus for those.
