Add custom devices helper (virtual)

[liamscarpa]

Describe your idea

Add helper to create a virtual custom device (curtain, gate, garage door, air purifier … )
So with proper automation you can assemble a device by others, plugs, switches, sensors, buttons…

Why is this exciting?

This would make more accurate devices types and more customization also using non specific devices

Potential use cases

Assemble an air purifier from a “dumb” air purifier connected to a smart plug and an external air quality sensor,
Assemble a gate or garage door from a radio frequency remote with buttons and a contact sensor

Anything else?
