ZigBee remote control

Hi!
I have 2 zigbee modules. The coordinator is connected to the Arduino module. To the Arduino button is also connected. The router is connected separately. A LED is connected to the digital output of the router. Which command should I send to the router to activate the LED? How to do it on arduino?

I have 2 zigbee modules.

What kind? How are they configured?

The coordinator is connected to the Arduino module.

With duct tape? A rubber band? A paper clip?

The router is connected separately.

To what? A tree? An old boot?

Which command should I send to the router to activate the LED?

What are you sending the "command" from?
