Z21

A small, event-driven .NET client for the ROCO/Fleischmann Z21 digital command station. It speaks the Z21 LAN protocol (V1.13) over UDP, so you can drive locomotives, throw turnouts, switch track power, read CVs and query system state — and get typed events back whenever something changes on the layout.

station.LocoInfoReceived += (_, loco) =>
    Console.WriteLine($"loco {loco.LocoAddress} now at speed {loco.LocoSpeed}");

await station.ConnectAsync();
await station.TrackPowerOnAsync();
await station.DriveAsync(3, DccSpeedMode.Steps128, DrivingDirection.Forward, 40);

You get an IZ21CommandStation from the DI container. To wire it up, add one of the companion packages: Z21.DependencyInjection (Microsoft.Extensions.DependencyInjection) or Z21.Autofac (Autofac). Both expose a single AddZ21(...) call.
