Trying to update the class of a device, via:

```auto
for (const device of Object.values(devices)) {
  if (device.zone != zombieZone.id)
    continue;
  if (device.class == "light") {
    device.virtualClass = "other";
    await Homey.devices.updateDevice({ id: device.id, device });
  }
}

```

But results in

```auto

How can I update the device from HomeyScript?

Looks like you can’t:

```auto
await Homey.devices.updateDevice({ id : device.id, device : { virtualClass : 'other' } });

Yeah, I tried the simple object form as well, without success. I’ve been able to update the device via e.g ` curl -X PUT -H 'Content-Type: application/json' -d '{"class":"other"}' <homey-url>/api/manager/devices/device/<device-id>` but I was hoping to do the same thing from HomeyScript.

And I can’t use `await fetch('api/manager/devices/device', ...);` as only absolute URLs are supported.

I don’t really understand how Athom blocks this operation from HomeyScript but you can still do it from an HTTP request 🤷🏼‍♂️

But you can make HTTP requests from HomeyScript using `fetch()`. Bit of a strange workaround, but if it works, it works.

You can probably use `http://127.0.0.1/api/manager/devices/device`

Thanks! This worked in the end:

```auto
for (const device of Object.values(devices)) {
  if (device.zone != zombieZone.id)
    continue;
  if (device.class == "light") {
    await fetch('http://127.0.0.1/api/manager/devices/device/' + device.id, {
      method: 'PUT',
      headers: { 'Content-Type': 'application/json', 'Authorization' : "Bearer <token>"},
      body: JSON.stringify({ 'class': 'other' })
    });
  }
}

```

A bit awkward to have to hard-code the authorization 🙂

(For context, I used this to turn a bunch of bulb light devices that I have aggregated into a single light via into class:other, so that Homey doesn’t report them as part of the “15 lights are on” in the latest mobile app update).

</div>

updateDevice and deleteDevice can only be used from the [Homey Developer Tools](https://tools.developer.homey.app/tools/api-playground).

As about changing the class of a device, you can just do: `myDevice.setClass('...');`

It means we can actually delete a device from a driver through this API! Good news.

Thanks for the tip about not being able to do updateDevice from HomeyScript, it worked i the developer tools as you say. But setClass doesn’t seem to work: `device.setClass is not a function`. No problem, I just use the REST endpoint 🙂

Surprising, my app ESPhome does it from the driver on existing device:

```auto
                    // Get virtual device
                    let virtualDevice = this.getDevices().filter(virtualDevice => virtualDevice.getData().id === virtualDeviceId)[0];

                    // Modify the class
                    if (virtualDevice.getClass() !== newDeviceClass) {
                        virtualDevice.setClass(newDeviceClass);
                    }

```

remark:: yes I could use find instead of filter 🙂

Right, the app can do it on its own devices, via the App SDK, but it’s not part of the JS API for the Web API

I have exactly the same issue : change the class of some devices from ‘light’ to ‘heater’.  
But, I was not successful using your code !!  
Could you give me more detailed process ?

I try this code, it seems working, but the new class does not remain after the end of the code …

You have to replace this with your actual bearer token. There are a few ways to do this, not sure which one is the best one: [homey get bearer token - Google Search](https://www.google.com/search?q=homey+get+bearer+token)

`device` is not updated dynamically, after you make the call to `fetch()` you need to reload the script to see if the class has changed (or go to [this page](https://tools.developer.homey.app/tools/devices)).

Finally, I got the bearer token by the mean of Robert Klepp code.  
And I was succesful changing the class of devices from light to Heater.  
Thanks a lot for your help
