class PoEInterface():
    """ This is the interface class for the Power over Ethernet ports on Extron devices (extronlib.device). The user can instantiate the class directly or create a subclass to add, remove, or alter behavior for different types of devices.

    Arguments:
     Host (extronlib.device) - handle to Extron device class that instantiated this interface class
     Port (string) - port name (e.g., 'POE1')

    Parameters:
    CurrentLoad - Returns (float) - the current load of PoE port in watts
    Host - Returns (extronlib.device) - handle to Extron device class that instantiated this interface class
    Port - Returns (string) - port name
    PowerStatus - Returns (string) - State of power transmission on the port ('Active', 'Inactive'). 'Active' if there is a device being powered by the port.
    State - Returns (string) - current state of IO port ('On', 'Off')

    Events:
    Offline - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Offline').
    Online - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Online').
    PowerStatusChanged - (Event) Triggers when the state of power transmission on the port changes (e.g. a PoE device is plugged into the port). The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Active' or 'Inactive').
