Stop Octopus daytime EV charging from draining your battery.

When Octopus dispatches a daytime charging session, your home battery drains to supply the car — automatically, every time. 1app stops it. These guides explain the conflict, the fix, and what else we coordinate across battery, EV, solar, and heat pump.

Private beta rollout

These are the energy conflicts 1app is built around.

Each use case below is a real problem in modern UK homes. The daytime Octopus EV-battery conflict is the flagship fix. The rest shows where 1app keeps adding value once that's solved.

Real conflicts, not theory

Every use case here is built around documented home-energy conflicts — not generic landing-page claims.

Discovery and qualification

Use these pages to understand whether your home already has the problems we solve before requesting access.

Mixed-device homes first

The best-fit homes are the ones where multiple devices already interact badly — battery, EV, and heat pump together.

Current use cases

Each page explains the operational problem, the whole-home consequence and where 1app.energy adds value across tariffs and devices.

Stop Octopus daytime EV charging from draining your home battery

This is the flagship 1app.energy wedge: stop the daytime EV-battery conflict first, then layer in cheaper-period battery charging and broader whole-home coordination.

Solar and battery optimisation for smart tariffs

This is the core 1app.energy use case: understanding whether solar, battery reserve and tariff timing are working together or fighting each other.

Smart tariff EV charging without home energy conflicts

When EV charging is cheap, it can still be operationally expensive if it competes with battery reserve, heating demand or export value elsewhere in the property.

Whole-home use case

Heat pump and solar coordination

Heat-pump homes need to know how solar generation offsets heating demand and when battery storage should protect the property from non-solar hours.

Solar, battery and EV charging in one app

This is one of the strongest SaaS acquisition pages because the value proposition is simple: stop managing three overlapping energy systems in three different tools.

Using battery storage to buffer heat-pump demand

For all-electric homes, battery storage can protect comfort and cost, but only if the reserve strategy is tuned to real heating behaviour and tariff opportunity.

Whole-home conflict detection for modern energy homes

The more flexible devices a home has, the more valuable it becomes to detect conflicts between them before they show up as cost, lost solar or poor comfort.
