Siri Integration

I have a scene that is says "bedtime" but Siri doesn't recognize it. How do use that scene using Siri? Also what would say?

Lutron hasn't added scene support to their HomeKit integration. It sure would be nice if they would...

Currently there is no way to activate scenes in the Caseta app with Siri/HomeKit.
I will forward your request to out developement engineers as a future feature request.
