Stop Octopus daytime charging from draining your home battery. Then automate the whole home.
When Octopus charges your EV during the day, your home battery absorbs the load — draining automatically to power the car. 1app detects the conflict and locks the battery out. Then it layers in tariff-aware reporting, cheap-period scheduling, and full coordination across EV, solar, battery, and heat pump.
Private beta rollout
We solved the painful problem first. The whole-home platform is already built underneath.
1app already handles battery protection during daytime EV charging, tariff-aware reporting, cheap-period scheduling, and the whole-home dashboard foundation. Access opens in deliberate waves — only where the setup fits.
Installer-led for real mixed-device homes
Built around how UK installers actually set up solar, battery, EV, and heat pump homes together.
Battery protection is the first fix
The daytime Octopus EV-battery conflict is solved before anything else — because it is the most expensive problem first.
Whole-home coordination already built in
EV, solar, battery, and heat pump coordination is already part of the platform foundation — not a future roadmap item.
Rollout paced deliberately
Selected vendor approvals are still in progress. We invite homes carefully so every rollout is safe and fully supported.
The full platform — already built
Stop the drain. Then keep optimising.
The first job is protecting your battery during Octopus daytime EV sessions. After that, 1app keeps working in the background — smarter charging periods, one view across all your devices, and manual control whenever you want it.
Charge in cheaper periods and keep it for later
- Top up battery energy in lower-rate windows
- Keep that stored energy for evening use
- Use tariff context instead of fixed schedules alone
- Review the cost impact in pounds, not guesswork
See the whole home in one place
- See EV, battery, solar, and grid together
- Add heat-pump context where supported
- Understand where power is going right now
- Use one calm view instead of four separate apps
Stay in control without daily babysitting
- Manual override whenever you want it
- Supported APIs only, no unsafe hacks
- Clear battery mode and timing visibility
- Safer rollout than ad-hoc setting changes
Heat pump insight
- Cycle and temperature trends over time
- Indoor vs outdoor temperature context
- Spot defrost / schedule issues earlier
- Heating vs hot-water energy split
Battery automation modes
- Autopilot, reserve, self-sufficiency and manual modes
- Clear charge / discharge timing visibility
- Battery protection during daytime Octopus charging
- Safer rollout than ad-hoc daily setting changes
Installer-friendly cloud access
- Secure login from any device
- Historical charts & trends (days to months)
- Remote view of home while you're away
- Share access with partner / installer
Got an EV, home battery, and an Octopus tariff?
That is the setup where the conflict is clearest — and where we focus first. Tell us what you are running and we will review whether your home fits the current rollout wave.
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, not pretending we are fully open.
Beta feedback, vendor approvals, and rollout readiness shape what expands next — and in what order. Early homes help set the direction.
