Whole home

You don't add the whole home yourself: Power Insight creates it from the devices you have set up. Its sensors live on two devices:

• Combined: totals across your whole home. The device name already says "combined", so the sensor names don't repeat it.
• Home base load (optional): everything your home uses that has no sensor of its own, meaning total consumption minus your consumers.

Turn the sensors on in the integration's Options → Combined sensors.

Power flow

Where the home's power goes

All power entering your home (grid import, solar and battery discharge), split by where it goes:

• Home consumption is everything your appliances draw, metered or not, from any source.
• Battery charging is power going into your batteries.
• System standby is the idle draw of your energy equipment, such as PV inverters at night. It does not include appliances on standby.

The ratio sensors show the same split as a percentage of all power entering the home, plus the share that is exported.

Debug readings

Diagnostic

Available power is all power entering the home: grid import + PV production + battery discharge.

Metering imbalance is how much more your metered devices drew than your sources supplied. Meters that update at slightly different moments make it briefly non-zero, and Power Insight evens that out on its own. If it stays large, a meter is probably set up wrong (an inverted sign, or a consumer meter inside another metered circuit), and a repair issue tells you so.

Cost

Every money sensor comes in a Standard and a Levelized flavour. See How it works for the difference. Sensors ending in rate are money per hour right now; Total sensors add it up across restarts.

Price of your electricity

What one kWh costs you right now, averaged over your whole energy mix. With Standard, grid power counts at the grid price and your own power is free. This is not your grid tariff: it drops as your solar and battery cover more of the load. Levelized prices your own power at each device's lifetime cost per kWh instead.

Blended price of electricity	EUR/kWh	Cost method: Standard
Levelized blended price of electricity	EUR/kWh	Cost method: Levelized

Cost per hour

What all the power entering your home costs per hour right now: the power × the blended price above. The cards below split it by destination.

Consumption cost

The part of the cost that goes to home consumption: what running your household costs.

Consumption cost rate	EUR/h	Cost method: Standard

Charging cost

The part of the cost that goes into charging your batteries.

Charging cost rate	EUR/h	Cost method: Standard
Levelized charging cost rate	EUR/h	Cost method: Levelized
Total charging cost	EUR	Total costs

Standby and export cost

The rest of the levelized cost: what your energy equipment's idle draw costs, and what producing the power you export cost. Only levelized, because at the grid price your own power is free.

Sensor	Unit	Turn on with
Levelized system standby cost rate	EUR/h	Cost method: Levelized
Levelized export cost rate	EUR/h	Cost method: Levelized

Device operating cost

What running your PV and battery hardware costs (their charging and standby draw), summed over all of them. Each device shows its own share as Operating cost.

Savings and financial return

Cost savings

Money saved by using your own power instead of buying it, minus what your devices cost to run. Export earnings are not included; see Financial return.

Sensor	Unit	Turn on with
Cost savings rate	EUR/h	Savings method: Standard
Levelized cost savings rate	EUR/h	Savings method: Levelized
Total cost savings	EUR	Total savings
Total levelized cost savings	EUR	Total savings + Levelized

Financial return

Everything your solar and batteries bring in: cost savings plus export compensation. The levelized version also counts what producing the exported energy cost, so it is lower than the levelized savings while you export for less than that cost.

Financial return rate	EUR/h	Financial return method: Standard

How the combined levelized totals are worked out

The combined levelized totals are not counted on their own. Each one is the sum of every device's own levelized total, plus whatever devices you have since removed contributed. That way, editing a device's lifetime values corrects the past too (see the correction factor), and removing a device never wipes out what it saved.

While a device's own total has no value yet, for example just after a restart, the combined total shows as unavailable rather than a partial sum, which would look like a false drop in your statistics. A device whose total you turned off is left out.

Home base load

Turn on Home base load under Options → Combined sensors → Power to get a separate device for everything without a sensor of its own: your fridge, lights, router and so on. Its power is your total home consumption minus the consumers you have added.

Base load

Power is what the rest of the house draws right now. Its attributes show where that power comes from (grid, solar, battery). Avoided cost rate is what your own power saved on that part of the house, at the grid price.
