# Tested with Python 2.7 and Python 3.6.1 only
Classes
OutletDevice(dev_id, address, local_key=None)
CoverDevice(dev_id, address, local_key=None)
BulbDevice(dev_id, address, local_key=None)
dev_id (str): Device ID e.g. 01234567891234567890
address (str): Device Network IP Address e.g. 10.0.1.99
local_key (str, optional): The encryption key. Defaults to None.
Functions
