1. The User Authorization Journey

The enrollment process begins when a user registers on the VPP platform and initiates the binding process. They are redirected to the FoxESS H5 Authorization Page. Crucially, upon successful authorization, the user will see a "VPP in Control" indicator in their Fox app, restricting their ability to manually control the device.

Key States in H5 Page:

State	Description	Required Action
Available	Compatible and free to bind.	User selects & confirms to proceed.
Used	Already bound to another VPP.	Stop: User must return to the original VPP app to unbind before proceeding.
Not Supported	Hardware model is not on the VPP whitelist.	Stop: Hardware is incompatible.
Upgrade Required	Model is supported but requires a firmware update.	Stop: Firmware update is needed.

Note on User Experience
Once the binding is confirmed, the device enters the "VPP in Control" state. This is visually enforced in the Fox mobile application to prevent user-VPP conflicts. Do not expect users to have manual control over dispatch parameters while enrolled in your program.
