mpf monitor doesn't show any devices

[worldpeace-germany]

Hi,

when running mpf monitor it doesn't show any devices in the device window. I see my playfield image, so mpf monitor works somewhat.

One part of my config file is for example

lights:
  some_led:
    number: 0-0-1
    subtype: led
    type: rgb

so I would expect to see that led in my device list. Do I have to do anything else? I was not able to spot anything else I have to do in the documentation.

Thanks.

Are you in a separate command prompt starting your game? MPF Monitor will load the image, but it will then load the devices and everything else once your game starts.
