What hardware do I need for a device farm?
Physical iPhones, a USB control chip per device, a Windows machine to run the kernel and agent, powered hubs, a rack and a network plan. The controlling software is Windows only.

The working build, component by component.
- iPhones. Refurbished is normal. Consistency of model matters more than being current.
- A control chip per phone. The USB device that lets software drive the handset.
- A Windows machine. The kernel service that talks to the chips is Windows only. A Mac cannot run it. This catches people out constantly.
- Powered USB hubs. Phones charging and transferring at once will brown out an unpowered hub.
- Rack, airflow and power. Phones generate heat. Heat throttles them and throttled phones fail jobs.
- Network. See proxies and mobile data.
