Async Device.js --> App.js

Voor mij wel.

// app.js
class MyApp extends Homey.App {
  async blink() {
    this.log('Blinking...');
  }
}

// device.js
class TestDevice extends Homey.Device {
  async onInit() {
    const app = this.homey.app;
    await app.blink();
  }
}

// console
[log] 2021-10-23 06:37:37 [MyApp] Blinking...
