⚡ Voltville a fiction on real infrastructure

Charging the invented city of Voltville. Monitored for real.

Voltville does not exist. Its 58 charge points do — as live simulated devices on real im/precise infrastructure: a real device gateway, real OTA rollouts, and a payment terminal that really keeps crashing, on purpose.

Why a fictional operator?

Screenshots lie easily; a living fleet cannot. Every number in the Voltville dashboard moves because a device sent it through the same gateway real hardware uses. The demo is read-only for everyone — the restriction lives in the account's credentials, not just the UI.

The story to follow: firmware 2.4.0 crashes the payment terminal at the Highway Hub, 2.4.1 fixes it — watch the crash cluster grow, then watch the staged rollout roll through Garage North.

The fleet

Garage Central 14 AC points
Garage North 12 AC points — mid-rollout
Depot 10 AC points, one straggler on 2.3.8
Highway Hub A7 12 DC fast chargers
Campus East 10 AC points incl. the cold store

The chargers phone home to iot.voltville.dev — a Custom Device Domain, so even the fictional operator gets its own endpoint.

The dashboard is the shop window. Point Claude at the fleet via the im/precise MCP server, or open the firmware in VS Code and debug a crashed charger's coredump with Pulse — against this very fleet.
