The HomeyScript editor auto-completes `HomeyAPI` that has a `call` function, but running it I just get `⚠️ ReferenceError: HomeyAPI is not defined`. Isn’t this supported?

`HomeyAPI` is a class which isn’t directly available (even though the editor suggests it is), but if you _really_ need it, you can use `Homey.constructor.call()` (since `Homey` is an instance of `HomeyAPI`).

Thanks @robertklep ! I tried that just now, but I’m getting `⚠️ TypeError: Cannot call a class as a function` for `Homey.constructor.call({ method: 'GET', path: '/api/manager/system'})`, so I guess that `call` operator is not whwat I’m looking for. Thanks anyways!

`.call()` is [`Function.prototype.call()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call).

Right… I was expecting it to be something else. Anyways, solved in [Homey.devices.updateDevice in HomeyScript](https://community.homey.app/t/homey-devices-updatedevice-in-homeyscript/88005)
