Battery Simulator
Energy arbitrage modelling for UK smart tariffs
Configuration
Real Consumption Data
Enter your Octopus API credentials to use your actual smart meter data instead of the synthetic model. Find these on your Octopus account page. Optional — the simulator works without these.
Privacy: Your API key is sent directly to the Octopus Energy API to fetch your data.
It is not stored, logged, or persisted by this application. All processing happens
server-side for the duration of your request only.
Fetching rates and running simulation — this may take 30–60 seconds.
