The __repr__() method should return object

[bitcanon]

When calling the repr() method of the Device class it should return a text that can be used to create a new object of that class.

Example:

Device(id='123-4567', zone='5', location='Livingroom', alerts=None, ...and so on)

You should then be able to copy that text and create a new object:

test = Device(id='123-4567', zone='5', location='Livingroom', alerts=None, ...and so on)
print(text.id)
