A Mac menu bar app showing live smart meter electricity use
Claude read the Octopus Energy API docs and built a SwiftUI menu bar app showing usage, rates and EV charging from a home smart meter.

The full story
Over the holidays the poster pointed Claude at the Octopus Energy API docs and built a Mac menu bar app in four evenings. It shows near-live power use from their own smart meter, the current rate with a countdown to the next off-peak window, EV charging status and history, and half-hourly usage sparklines.
Claude read the docs and worked out authentication and queries, built a Python client, and scaffolded a SwiftUI app using the Xcode build MCP. The poster says the models build exactly what you ask for, including plenty of slop, and keep adding features unless you stop them. The project is open source.
