MQTT Topic TTN

Thank you for your reply as well in this topic!

Im saving both of them so I now exactly which device made this measurement?

You mean I need to check what I’m getting after the change node?
As far as I understand what you want me to know I made to debug nodes. One with the “msg.payload” and one with the “msg.dev_eui”.
is this what you meant?

Thank you very much in advance!
