Does anyone has an idea how to proceed from here? Ok, so we can receive Voice-to-Text message inside NR and "play" with them. As far as I understood the Alexa concept you can add IoT devices but then all your switches and lamps are configured somewhere in the Amazon-Clouds and no longer in NR?
I guess its possible to configure your very own NR Raspberry to be the destination "device" for Alexa and then configure your Raspberry as actor on voice commands directly (with NR but without any cloud service?)
I assume this requires to develop a real "Alexa skill" on a more professional level?
