Multi windows in tkinter buttons not responding correctly

[Barrowman]

I haven't been using classes myself but looking at this and other ( working ) examples of code I think you need a change:

class Fireplace()
    
   def __init__(self):

       if (bus1.read_pin(15) == 1):
          bus1.write_pin(15, 0)
          toggleButton1["text"] = ("Fireplace On")
           
       else:
               bus1.write_pin(15, 1)
               toggleButton1["text"] = ("Fireplace Off")
    
  

to this:

 class Fireplace@
   def __init__(self):

       if (bus1.read_pin(15) == 1):
          bus1.write_pin(15, 0)
          Mainfloor.toggleButton1["text"] = ("Fireplace On")
        
       else:Mainfloor
               bus1.write_pin(15, 1)
               Mainfloor.toggleButton1["text"] = ("Fireplace Off")

Of course I may be wrong as I usually am
