Mike runs his battery, EV charging and Octopus tariff from one dashboard.
A 15 kW Solis inverter. Four Fogstar batteries. A three-phase MyEnergi Zappi. Octopus Intelligent Go in the background. 1app.energy ties them together so Mike can see — and automate — the whole three-phase home from one place.
Clear enough for daily use. Specific enough for a complex home.

“1app.energy is a clear, reliable app for managing my home energy in one place. I use it to monitor electricity usage, my home battery system, and EV charging, with everything presented in a straightforward, easy-to-understand dashboard. The automated features are a real strength — including tariff optimisation and the ability to export surplus energy back to the grid automatically based on remaining battery capacity. Overall, it's a well-designed app that takes the effort out of managing a modern home energy system.”

What's actually installed at Mike's house.
Each piece of hardware shows up in the same operating view — so Mike never has to flip between four different apps to understand what the home is doing.
15 kW Solis inverter
A large-format Solis inverter manages battery flow across all three phases of Mike's home — visible in the same view as demand, grid import and export.
Four Fogstar batteries
Four batteries' worth of storage, shown as one pack: state of charge, charging behaviour and reserve are visible at a glance throughout the day.
Three-phase MyEnergi Zappi
A three-phase Zappi handles EV charging across the home's full supply — and sits next to battery, tariff and grid context in the same dashboard.
Octopus Intelligent Go
The current rate, off-peak windows and standing charge feed into the daily cost view and into when the system imports, exports or charges the EV.
If your home looks like Mike's, this is what you get.
Mike's setup is a larger-than-average home: a three-phase supply, a 15 kW Solis inverter, four batteries and a three-phase EV charger. Here's what 1app.energy does with those pieces — and the same logic scales down to a single-phase home with one inverter, one battery and a single-phase Zappi.
One app instead of four
Solis, Fogstar, MyEnergi and Octopus all surface in a single dashboard. No more bouncing between apps to understand what the house is doing.
Automation that watches the tariff
Mike's setup charges during cheap windows and exports surplus when the tariff and battery level make it worthwhile — automatically, based on tariff and battery level.
Easy to read every day
In Mike's words: a straightforward, easy-to-understand dashboard. The complexity is in the automation, not on the screen.
Works with the kit you already have
No new hardware needed. Mike's existing Solis inverter, Fogstar batteries and Zappi charger all plug into the same operating view.
Honest note:automation depends on supported devices, verified tariff data and the settings you turn on. Mike's story shows one real setup — your exact features will depend on the hardware in your home and the onboarding review.
