Hi, im starting with HomeyScript and right at the beginning have a question.

i have this construction

```
let someDevice = await Homey.devices.getDevice({id: 'ed766ab2-21fb-44cf-b9c6-d58bf75bed44'});

```

why i can’t use

```
someDevice.getCapabilities()
//or
someDevice.getCapability('measure_temperature')
// returning someDevice.getCapability is not a function

```

only way i found is

```
someDevice.capabilitiesObj.measure_temperature

```

?  
thanks

Homeyscript uses the [Web API](https://developer.athom.com/docs/api), not the [App API](https://apps.developer.athom.com/).

So `Homey.devices.getDevice()` returns a [`HomeyAPI.ManagerDevices.Device`](https://developer.athom.com/docs/api/HomeyAPI.ManagerDevices.Device.html) instance. And the only method this instance has is [`makeCapabilityInstance()`](https://developer.athom.com/docs/api/HomeyAPI.ManagerDevices.Device.html#makeCapabilityInstance).
