BLT presence monitor.sh in docker environment - "no such device"

Hi,
Is anyone able and willing to share their configuration for getting Andrew (https://github.com/andrewjfreyer/monitor) program running on the laptop that hassio docker is using ?
with embedded MQTT ?

Just to clarify further, I have a laptop running Ubuntu xenial
On it I deployed HASSIO
MQTT is running as an add-on

I have installed monitor on the laptop , configured mqtt_preferances to use the correct username / password from mqtt addon but all I get is “no such device”

/monitor.sh -c A8:2B:B9:02:E0:27
