I set these properties to my endpoint:
{  
   interface:"Alexa.PowerController",
   version:"3",
   type:"AlexaInterface",
   properties:{  
      supported:[  
         {  
            name:"powerState"
         }
      ],
      retrievable:false,
      proactivelyReported:true
   }
}
 
When my device state change, I call ChangeReport API to update its state, the gateway return
success (202) but the Alexa app does not update its newest state. So updating live is not current supported or this my bug or anything else?
Thank for your help.
