This app is no longer supported due to the classic app sunset on the 14th October and Groovy sunset within the next 6 months, I will not be updating to the new API as I have moved to hubitat and using CoCoHue on there instead.
If smartthings hasn’t added local control of groups & scenes to its official hue integration before the Groovy sunset I would recommend you look into dumping ST they are just to slow to add features
