Python won't recognise attribute
The Tkinter module is a little old-skool; the text value can be accessed via an item lookup:
relStatus.set(fire['text'])See the Setting Options section of the Tkinter documentation.
topLabel = Label(app, textvariable = labelText, height = 5).pack() # so topLabel is NonetopLabel = Label(app, textvariable = labelText, height = 5)topLabel.pack() # topLabel is Label
