HA Core does not sees SySensors gateway

Hia,

i built the mysensors gateway, have it on the network, can ping to it, but HA Core does not sees it.

my configuration.yaml is:

default_config:

# Text to speech
tts:
  - platform: google_translate

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
http:
  ssl_certificate: /var/homeassistant/.homeassistant/server.pem
  ssl_key: /var/homeassistant/.homeassistant/server.key

#map:

geo_location:
  - platform: geo_json_events
    url: https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_day.geojson


mysensors:
  gateways:
    - device: '192.168.80.9'

Any hint in how to integrate it?

Best regards,

Paulo Ven
