Property or method "checkDeviceStatus" is not defined on the instance but referenced during render

This error message usually occurs when you are referencing a property or method in your Vue component's template that is not defined in the component's instance.

To fix this issue, you need to make sure that the `checkDeviceStatus` property or method is defined in your component's instance. Here are a few steps you can follow to resolve this error:

1. Verify that you have defined the `checkDeviceStatus` property or method in your component's `data` or `methods` section. For example:

data() {
  return {
    // ...
  };
},
methods: {
  checkDeviceStatus() {
    // ...
  },
},

2. Check if you have properly bound the `checkDeviceStatus` method to the template using the `v-on` directive. For example:

<button v-on:click="checkDeviceStatus">Check Device Status</button>

3. If you are using the `checkDeviceStatus` property instead of a method, ensure that it is properly defined in your component's `data` section. For example:

data() {
  return {
    checkDeviceStatus: true,
    // ...
  };
},

By following these steps, you should be able to resolve the "Property or method 'checkDeviceStatus' is not defined on the instance but referenced during render" error in your Vue component.
