Using Smart Oven with Alexa

[octoplayer]

Hi,

Just got a Dual oven Series 5. I can control / monitor it via the App, and I have linked the app to my Alexa skills.

However, when I ask Alexa to turn off or set the oven it says "I am not quite sure what went wrong".

If I try a routine, the only action options are turn turn the Oven light on or off, or set brightness (Bright or off), which do nothing.

Am I missing something, or is Alexa not really supported?

Thanks
