Has there been any movement on this?
I too would find this tremendously useful, for controlling the temperature, blinds or Sonos playback in a given room, as there would be a specific Echo Dot in that room.
Can someone from Amazon please make a comment on this mentioning whether this feature is going to be implemented or not? It's a very fundamental need while building applications for multiple Alexa devices.
It's here! Check out "deviceid" here: https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/alexa-skills-kit-interface-reference#request-body-syntax
The context that's sent to AWS doesn't contain the device id. I don't use the http interface, I go through mqtt. It doesn't show up in the mqtt message either.
If you want to find the mac address of your own device you can find it in the Settings, Devices area of your Amazon Alexa mobile app. If you know the mac address of your device you can use network tools such as arp-scan to find the ip address of the device. This will only work if you are on the same network as the device. This is useful if you are deploying devices to different rooms in a home or office.
