You have debug verbosity on which shows that your sensor on/of signal as such is recognized by pimatic.
Your used class is correct as well.
Did you specify the protocol in the mysensors plugin?
{
      "plugin": "mysensors",
      "driver": "serialport",
      "protocols": "1.5.4",
      "driverOptions": {
         "serialDevice": "/dev/ttyUSB0",
         "baudrate": 115200
      }
    },
The plugin still defaults to the 1.4 protocol.
Edit: Also check Getting started with MySensors in the pimatic forum.
