Hi all,

I have a serial gateway connected to the RaspberryPI running Hass.io.
I've also built a sample BinarySwitchSleepSensor.
I can see the logs on the serial gateway - it seems like it receives the messages from the sensor just fine.
My problem is that I cannot see the sensor in the Home Assistant, no matter what I do...
Running ls -l /dev/tty* command brings me this:

The configuration.yaml contains the following section:

mysensors:
  gateways:    
    - device: '/dev/ttyAMA0'          
  optimistic: false
  persistence: true
  retain: true
  version: '2.0'

In one of the attempts I actually saw the sensor (even two, for some reason) though the state never changed.
I'm unable to see them anymore...

Some more info:
After RPI reboot, the "hassio hardware info" command shows:

But after reattaching the USB I see

So, it seems like the gateway is invisible after the boot. Chanding ttyAMA0 to ttyUSB0 in the configuration file just results in error notification on boot...

Can someone please help me with this? What am I doing wrong?

Thanks,

Alex
