Particle.subscribe() how to get sender device ID?

Hi there,

How is it possible if possible to get addition information about event when it comes? The cloud has all information about event like date, time, source device, but I can’t find the way to get this information in the event handler.

That information is not available to the handler. Only the event name, and the data sent with it. If you need that information, you will need to send it as part of the data.
