Features
Everything your energy is doing.
And what it should do next.
IonVolt shows your home's power as it happens, keeps every day on record, and runs the battery for you when you want it to.
The house view
Your home, live, in 3D.
A model of a house with your solar on the roof, the battery on the wall and the car on the drive. Lines of light show where the power is going, in each energy's own colour.
- Follows your sky. Real sunrise and sunset, the moon at night and the weather where you live.
- Make it yours. Choose your house's colours with Pro.
- Today at a glance. Solar made, power bought and sold, and how self-powered you were.
Controls
Your battery, your rules.
Change your house battery from anywhere, without the maker's app.
- Work mode, grid charging, charge and discharge times, battery limits and back-up power, depending on your system.
- Read back, every time. IonVolt checks each change with your house battery and tells you if something didn't stick.
- Safe by default. Changes stay off until you turn on Allow changes, and Face ID or a fingerprint can be asked first.
Smart charging
Charge when power is cheapest.
IonVolt plans your battery around your tariff, tomorrow's solar forecast and how your home uses power, then sets your house battery's times itself.
- See the plan for the next 24 hours, with prices, the battery level and the estimated saving.
- Works with your tariff, from Octopus, EDF or E.ON Next when you link your supplier, or rates you type in.
- Your rules still come first. Turn it off and your own settings go back on.
Free Hours
Fill up when power is free.
Suppliers sometimes give power away, or sell it at half price. IonVolt finds those hours and charges the battery in them.
- Found for you from your linked supplier, such as Octopus Power-ups and EDF's free half hours.
- Or add your own, once or every week, free or half price.
- A heads-up when free power is coming, 30 minutes before, and when it ends.
Money and carbon
See what today cost, and saved.
Every hour priced from your own tariff, with what you earned from export taken off. And the CO₂ your solar and battery kept out of the air, from the grid's real carbon intensity where you live.
- Charts for every day, month and year: solar, battery, house, grid and car.
- Standing charge and export included, so the total matches your bill.
Car guard
Charge the car. Keep the battery.
Without it, a house battery can empty itself into the car. When the car starts charging, IonVolt holds the battery for the house, and puts your settings back when the car is done.
- Knows when the car is charging, from your charger (Hypervolt, Zappi, Ohme, Wallbox, Pod Point or Easee) or from the power the house is drawing.
- Charge the battery too if power is cheap: one switch.
Widgets and Live Activities
No need to open the app.
Widgets for the Home Screen and Lock Screen show the battery, solar, the house and the car. While the car charges, a Live Activity keeps you posted on the Lock Screen.
- Alerts that matter, free for everyone: house battery offline, back-up power off, battery low.
Apple Watch
On your wrist, at a glance.
The battery, solar and what the house is using, complications for your watch face, and the work mode a tap away.
iPhone Duo

Folded, IonVolt fills the cover screen, with its tabs in a rail beside the camera. Open it and it uses all of the big screen: the house above, the battery and the day's chart below.
