Are there any widget that can chose colors of the lamps?
Not yet. It will be part of light widget that is coming soon.
Waiting impatiently!
Any updates? App is in Beta. It is half useful without this widget
@yvh65 Light widget is literally at the top of new widget list 
Should be coming in one of the next few releases. I appreciate your patience!
Any news on the widget?
Nothing really new to say at this moment. Still in progress, should be the next widget to be released.
