我如何在 kivy 中不断更新我的标签？

我已经被这个问题困了几个小时了。我正在制作一个自制的智能家居终端，并且已经对 kivy 进行了大约 2 周的修补，到目前为止它一直很棒。我现在想在屏幕内显示标签内的温度。我制作了一个带有 4 个按钮的操作栏，单击时可以在屏幕上滑动。在名为“Thermostaat”的第一个屏幕中，我想显示一个标签，其中包含从我编写的另一个外部脚本读取的温度。我似乎无法获得标签内的温度，即使是虚拟值也是如此”这是我的 main.py：

#!/usr/bin/env python3
from kivy.app import App
from kivy.uix.screenmanager import ScreenManager,Screen
from kivy.properties import ObjectProperty, StringProperty
from kivy.uix.boxlayout import BoxLayout
from kivy.clock import Clock
from kivy.uix.label import Label
from kivy.lang import Builder

class Menu(BoxLayout):
    manager = ObjectProperty(None)
    def __init__(self,**kwargs):
        super(Menu, self).__init__(**kwargs)
        Clock.schedule_interval(self.getTemp, 1)
    def getTemp(self,dt):
        thetemp = 55 #will be changed to temp.read()
        self.ids.TempLabel.text = str(thetemp)
        print(thetemp)

class ScreenThermo(Screen):
    pass

class ScreenLight(Screen):
    pass

class ScreenEnergy(Screen):
    pass

class ScreenWeather(Screen):
    pass

class Manager(ScreenManager):
    screen_thermo = ObjectProperty(None)
    screen_light = ObjectProperty(None)
    screen_energy = ObjectProperty(None)
    screen_weather = ObjectProperty(None)

class MenuApp(App):
    def thermostaat(self):
        print("Thermostaat")

    def verlichting(self):
        print("Verlichting")

    def energie(self):
        print("Energie")

    def weer(self):
        print("Het Weer")

    def build(self):
        Builder.load_file("test.kv")
        return Menu()


if __name__ == '__main__':
    MenuApp().run()

这是我的 .kv 文件：

#:kivy 1.10.0
<Menu>:

                on_release: app.thermostaat()
            ActionButton:

                on_press: root.manager.current= 'light'
                on_release: app.verlichting()

        manager: screen_manager

我不断收到以下错误：

super(ObservableDict, self).__getattr__(attr))
 AttributeError: 'super' object has no attribute '__getattr__'

这是我的追溯柜面你想知道：

我希望有人愿意帮助我解决这个问题，因为我想继续这个项目，我的 SmartHome 设备的大部分功能已经可以工作了，所以最后一部分是制作一个像样的 GUI 来适应它（控制灯光，控制房子里的温度等......）
