ok. i have installed node red using this guide and it was super easy. I also manage to play around with Alexa Local and Alexa Home Skill together with node-red-contrib-home-assistant. I can turn my devices on/off easily. But what I don’t understand is do I need to create flows for every single devices I want to control? For example, if I have 100 devices, do I need to create 100 flows?
Another problem is all devices discovered via either Alexa Local or Alexa Home Skill is identified as lights. This makes it unable to achieve what I described here.
