I'm working on a code to update my temperature sensor together with a timer and translate this into the gauges on my Gui. the problem is somewhere in the updater code since that is the only code that creates error codes to be more precise this error code: "type object 'MainFrame' has no attribute 'MainTemp_meter1'".
i tried different codes and code styles to get the updater to work but none of then worked so far. Now with the latest one i can atleast keep the Gui running but i can't update anything yet. [imports used]

def update_readings(self):
try:
while True:
# Update temperature reading
temp_reading_top = sensors.sensor.read_temperature()
humid_reading_top = sensors.sensor.read_humidity()
MainFrame.MainTemp_meter1.set(temp_reading_top)
DiagFrame.temp_meter1.set(temp_reading_top)
DiagFrame.humid_meter1.set(humid_reading_top)
# Update current date and time
date = dt.datetime.now()
MainFrame.label_timedate.configure(text=f"{date:%A, %B %d, %Y, %H:%M}")
# Update timer label
timer_reading = self.timer_frame.timer10.read_current()
formatted_time = timers.Timer.format_time(timer_reading) # Call format_time from timers.Timer
self.timer_frame.time_var.set(formatted_time)
print('updated')
# Update the GUI
MainFrame.update_idletasks()
DiagFrame.update_idletasks()
TimerFrame.update_idletasks()
# Delay for a certain period (e.g., 1 second)
time.sleep(1)
except Exception as e:
print("Update error:", str(e))
# Create and start a separate thread for the update loop
update_thread = threading.Thread(target=update_readings, daemon=True)
update_thread.start()
up until now i was expecting to get the updater online and make my code work so i can monitor different situations as i like. Some examples of the use are for measuring the temperature inside or outside together with the humidity and put that in a log so i can see what the temperature was around 3 in the morning.
