In the Device SDK, there is methods for detecting things like `onAdded` and `onRemoved`. But is there any way to detect that the device has been moved to another zone? I tried the `onSettings` method, but it is not called when changing zone in a paired device.

_Possibly_ through the [`zone.update` event](https://developer.athom.com/docs/api/HomeyAPI.ManagerZones.html#.event:%2522zone.update%2522) in the Web API. I don’t think there’s anything in the Apps SDK available.

Do you have an example of an app on github or somewhere else using events from the Web API? I am wondering a bit on how to manage the manager context and such.

Homeykit subscribes to `device.update` events: [https://github.com/swttt/com.swttt.homekit/blob/233af11a0ff81638076157f7b76c9c32dae755ea/app.js#L92](https://github.com/swttt/com.swttt.homekit/blob/233af11a0ff81638076157f7b76c9c32dae755ea/app.js#L92)

Ah, I was afraid I had to instanciate a manager object and wanted to avoid mem leaks. This worked, and it was emitted when zone was changed.

Thank you very much!
