Entity reference
This is the full list of sensors Power Insight can create, grouped by scope. Which sensors actually appear depends on the options you enable — see Sensors, presets & options.
Currency units
Sensors are documented in EUR for brevity. At runtime the EUR unit is
replaced with your Home Assistant currency (e.g. $/h, £/kWh).
Entity names may change
Power Insight is in beta; entity names may change until 1.0.
info
ratio vs. share — they are not the sameEvery percentage sensor is one or the other, and the denominator differs:
… ratio— a fraction of the scope's own power: for a device, its own production/throughput (e.g. Export ratio = the fraction of this PV system's production that is exported); for the whole home, gross power.… share— this device's slice of a home-wide total (e.g. Export share = this system's exports ÷ all power exported by the home).
See Power distribution → ratio vs. share for the full definition.
Legend for the Enabled by column — the option/category (and where relevant the device capability) that must be on for the sensor to exist:
- Distribution (W/ratios/shares) → the matching Power sensors category.
- Cost — Standard / Levelized → the Cost calculation method.
- Savings — Standard / Levelized → the Savings calculation method.
- Financial return — Standard / Levelized → the Financial return method.
- Accumulate … → the matching accumulate toggle.
Combined (whole home)
These aggregate power and cost across your whole home — they sum all your devices into a single number per metric.

Combined levelized totals are derived, not integrated
The levelized totals are computed as the sum of each device's own levelized total (scaled by its correction factor) plus a ledger of removed devices — so editing lifetime values is retroactive and removing a device never drops its historical contribution.

Battery
Per battery device. The battery has the same sensor set as a PV system (above) — including cost savings, financial return, and their levelized variants — reading the battery's own values, plus dynamic charging-source sensors. (Its own Charging ratio/share sensors only appear when another battery is configured to charge from this one — battery-to-battery charging — so in most setups they are absent.)

|---|---|---|---|
| Charging source shares (one per configured source) | % | Share of the battery's current charging power coming from each source (e.g. "70 % solar, 30 % grid"). One sensor per source selected in Charges from. | Charging source shares |
For the battery, the levelized quantities use the battery's LCOS instead of an LCOE. See Battery configuration.
