I am. What are you having problems with? Remember, you have to add the device to WebCore the same way you would a light or a switch after you create it. Once that’s done, you can use the speaker as a voice synthesis device. If you are trying to use WebCore to play a media file for an alarm or whatnot, that is something that WebCore can’t do I’m pretty sure. However you can use WebCore to trigger a virtual switch and then use a SmartApp called Speaker Notify with Sound. This doesn’t allow you to pick any old noise you want but there are several there to choose from.
