    network_mode: host
    volumes:
      - /opt/home_assistant/:/config
      - /etc/localtime:/etc/localtime:ro
      - /opt/ssl:/ssl

  homebridge:
    image: oznu/homebridge:raspberry-pi
    container_name: homebridge
    restart: always
    network_mode: host

      - PGID=1001
      - PUID=1001
