I got a zigbee binding. Friend of mine programmed it and got it working on his openhab2 instance.  
Brought it over to my house and tried to get it to work and can’t.  
It shows up on the serial port in ubuntu, but we see this in my openhab2 log.  
Thoughts?

Have you done this [Zigbee binding - #100 by curlyel](https://community.openhab.org/t/zigbee-binding/15763/100) yet?  
This is something I forget sometimes …

If this won’t help (assuming you’re on a Raspberry Pi), then go through the whole procedure for solving serial port issues on RPi as described here [OpenHAB2 + Razberry + Z-Wave Binding - #26](https://community.openhab.org/t/openhab2-razberry-z-wave-binding/13033/26)

Hope that helps 😉
