EdgeAppliance

An appliance-style EdgeDevice described by a single power and lifespan, without breaking out individual components. Suitable for sealed devices whose internal hardware is not modeled separately.

When to use this class

Use EdgeAppliance when only an aggregate power and embodied carbon are known, and the load is described as a 0..1 workload curve. Use EdgeComputer for computer-like devices with CPU, RAM, and storage. Use EdgeDevice for fully bespoke hardware with custom components.
