Is it possible to identify in WebCORE which Amazon Echo device activated a switch

Hi everyone!

I have an Alexa routine that, when I ask "Which are the temperatures?" it activates a virtual switch and, then, a WebCore piston tell me which are the temperatures at my balcony, living room and bedroom.

It works fine and I use to amuse my friends on how smart my home is ... :upside_down_face:

However, I always give the answer to a specific Echo device and I would like to send the answer for the exactly Echo device which commanded the switch activation ... It would be very nice, and, of course, even smarter!

Thanks in advance.

This might be possible with Echo Speaks. In any event, it is definitely possible using Node-RED and this set of Alexa nodes.
