Using Amazon Alexa combined with newly added Lutron integration works pretty well. I can control individual lights as well as grouping created in the Alexa app. Commands such as device/group name off and on work as well as device/group name xx% brightness all work. The name brightness command will also turn the device(s) on at that brightness level if they were off.
Also found an App for IOS and Android called Roger. It has Alexa integration and I can tap to talk to Alexa and control the lighting with the same commands. There is a ~3 second delay before execution. The app creates a new Alexa device within the Alexa app and you will want to go into the new Roger device on Alexa App and set the zip code to your zip code.
