I am trying to write an app in typescript. But when I don’t have any type definitions available, such as:

```
interface Device {
  id: string;
  name: string;
  ...
}

```

I have to define them myself and maintain them in line with changes in the Homey code to ensure that type-related bugs in my code are avoided, which sort of limits the gains of defining types. So I was hoping there would be official type definitions that are maintained by the devs along with the changes in the Homey code/API.

The [`homey`](https://www.npmjs.com/package/homey) package contains type definitions: [https://github.com/athombv/node-homey/tree/master/sdk/lib](https://github.com/athombv/node-homey/tree/master/sdk/lib)
