hi I’m trying to update my widget based on an event from the device.  
In the device I have this.homey.emit(“myEvent”); (which works just fine if I call this.homey.on(“myEvent”) in the same device.

When I call this from the widget I don’t get any event:  
Homey.on(“myEvent”, () =\> doSomething());

does anybody have a tip? I couldn’t find this in the docs, it seems it could be here: [Custom Pairing Views | Homey Apps SDK](https://apps.developer.homey.app/advanced/custom-views/custom-pairing-views)  
but that link is not working

Poorly (read: _not_) documented:

```auto
this.homey.api.realtime('myEvent', ...);

```

You are gold! thanks!  
For future reference:  
in the device:  
this.homey.api.realtime(“myEvent”, …);  
in the widget.html:  
Homey.on(“myEvent”, () =\> doSomething());

anyone know if its possible to update the settings? I have 2 settings, and if I select one boolean the dropdown beneath needs to be cleared so set to null for example. I see you can only use getSettings(). normally you can do the.homey.settings.set but this is only for the app settings not the widget settings

No, I also searched, but it seems it’s not possible.

Is it maybe a workaround to pass the setting to the app, and store them with a widget id? When you initialize the widget you can retrieve them
