One app for solar, battery, EV and tariff homes. Built around real Solis battery problems.
1app.energy gives supported UK homes one place for live flow, source-aware reports, grid import/export, battery charge and discharge context, Zappi charging, Ohme and Hypervolt monitoring, and Octopus tariff timing. For supported Solis homes, Smart Control can also protect the battery during eligible daytime EV charging. SunSynk and Hypervolt are available as beta monitoring paths without control claims.
Controlled rollout
The painful Solis battery problem led to a wider whole-home platform.
1app already brings together live energy flow, tariff-aware reporting, battery charge and discharge sources, EV charging context and supported Solis controls. Customer onboarding is open in deliberate waves so each setup is supported properly.
Built from real Solis and mixed-device homes
Built around how UK installers actually see solar, battery, EV, tariff and grid behaviour interact.
Battery protection is the first fix
For supported Solis homes, the daytime Octopus EV-battery conflict is handled before broader automation is expanded.
Whole-home visibility already built in
The live Nexus view, energy reports, source mix and diagnostic surfaces are part of the platform foundation.
Rollout paced deliberately
Solis is the mature control path. Ohme is supported for EV charger context where enabled. SunSynk, LuxPowerTek and Hypervolt stay clearly marked as beta.
The full platform, already built
One coherent view. Smarter decisions.
1app.energy brings live flow, supply mix, battery charge and discharge sources, grid import and export context, Solis battery controls where supported, and diagnostics where the connected hardware exposes them.
Know where every kWh went
- Source-aware home, solar, battery, EV and grid reports
- Battery charge and discharge breakdowns
- Grid import and export context
- Net cost views in pounds, not guesswork
See the whole home in one live view
- Coherent Nexus view across solar, battery, grid, EV and home
- Last-known-good handling when live telemetry is incomplete
- Clear current flow instead of conflicting app readings
- One calm view instead of four separate apps
Solis Smart Control where supported
- Protect the battery during eligible daytime EV charging
- Use off-peak and tariff windows with reserve context
- Manual, reserve and self-sufficiency modes where enabled
- Customer-enabled controls with safety gates
Diagnostics where telemetry exists
- Inverter temperature and operating health where available
- Battery health, cycle and degradation context where supplied
- Stale telemetry and data-gap warnings
- Supportable evidence instead of vague app screenshots
Battery and export decisions
- See when battery timing matters more than export rate alone
- Understand charge source and discharge destination
- Review reserve behaviour before EV and tariff decisions
- Keep export limits and tariff context visible
Built for supportable onboarding
- Solis live onboarding and control where supported
- SunSynk beta monitoring without unsafe command claims
- LuxPowerTek beta, Ohme and Hypervolt beta support with limits shown first
- Encrypted access and clear rollout boundaries
Got solar, a battery, an EV charger, and a time-of-use tariff?
That is the setup where whole-home context matters most. Start with your inverter so supported homes can continue without waiting.
Built to stop the daytime EV-battery conflict first. Then optimise the rest of the home around it.
The first job is battery protection during daytime Octopus EV charging. After that, 1app helps you use cheaper periods more intelligently, see whole-home flows in one place, and coordinate EV, solar, battery, and heat pump behaviour.
We detect
Octopus daytime EV charging starts
1app monitors your Octopus account and spots when a smart-charge session is scheduled during the day, before your battery starts draining.
We protect
Battery discharge locked out automatically
The moment the session window opens, 1app applies your battery protection rule. Your stored energy stays put. No manual inverter changes needed.
We optimise
Cheaper periods used intelligently
Outside conflict windows, 1app schedules top-ups during the cheapest rate periods and keeps that energy available when you need it most.
Next in the rollout
We are building carefully, expanding in controlled waves.
Customer feedback, vendor approvals, and rollout readiness shape what expands next, and in what order. Onboarded homes help set the direction.

Anomaly alerts
This looks off vs your usual pattern for heat pumps, solar and EV behaviour - before the bill shocks you.
Installer / multi-home
One view for multiple homes. Spot issues proactively and offer premium monitoring as a service.
Your setup might already qualify.
Choose your inverter first. Solis can continue to account creation, SunSynk can join beta monitoring, LuxPowerTek can confirm beta access, and other brands can join the compatibility list.
