XBee collect data

Hi, i use XBee modules with breadboard on which i can connect sensors and i want to collect this data via Node-red. I saw this video, which use XBee with NR, but don't understand how to collect sensor data from the XBee. Any help?

So what have you tried?
A hint: look for and try with XBee nodes.
A second hint: Manage pallete...

I've try the video above, but i can't see all sethings in the video and can't meke all config's properly.
I try all XBee nodes in NR [Library - Node-RED] , but don't know how to make the right config's.

Please, any help?
