Mysensors config problems

Hya,

i have the following in my configuration.yaml.


mysensors:
  gateways:
    - device: '192.168.80.9'
      persistence_file: '/var/homeassistant/.homeassistant/mysensors.json'
  optimistic: false
  persistence: true
  retain: true
  version: 2.2    


but insted of the define persistent file, it creates

/var/homeassistant/.homeassistant/mysensors_6b6325769864339b5021712ded3e8c18.json

any clue why the defined finename is not being used from configuration.yaml?

Thx in advance!
