Intro

1app.energy is a web app for coordinating whole-home energy behavior in UK homes with battery and EV setups. It is built around a specific issue: when Octopus starts charging an EV during the day, the home battery can drain into the car. The app is designed to stop that automatic battery drain.

Key Features

• Automatically stops the home battery draining into the EV when Octopus daytime charging begins.
• Coordinates energy across solar, battery, EV, and tariff behaviour.
• Uses controlled onboarding.
• Includes setup and support information through a FAQ and knowledge base.
• Typical setup is £0.

Who this is for

This project is for UK homes with battery and EV systems, especially users with Octopus Intelligent Go or similar daytime EV charging behaviour. It is relevant where the connected devices support the needed behaviour and the Octopus charging pattern creates the battery-to-car conflict described above.
