Responding to last Alexa device

I am not sure how to get WebCore involved but you can definitely get Last Device Spoken To if you are willing to go down the Node Red rabbit hole.

Node Red Room Aware Voice Control

Hello all. I want to be able to say a direct command against Alexa or Google Assistant without skill invocation, and then receive the request within Node Red along with the originating device serial ID or friendly name. This will enable room awareness within NR. Alexa, turn on the toaster. Node Red receives the following... requestMessage "Alexa, turn on the toaster" deviceSerial: "XYZ" deviceFriendlyName: "Office Echo" Any ideas how to make this happen?

When using the node-red-contrib-alexa-remote2-applestrudel pallet that @aaiyar mentioned, it provides the value msg.payload.deviceSerialNumber for each of your devices.
