What port or protocol does Discovery run on

What port or protocol does discovery work on? I have a virtual Hass.io set up on a separate vlan which is working quite nicely as it sees Tv’s as media players, a Plex server and can control them, all on different vlans. For some reason it is not seeing all of my google home minis (4) as such. They do show up as device entitys only because I have my router set up for that. Any suggestions or any rules I can set up in the firewall to allow it to see the minis? I should add that I am on .84.5 if that makes a difference.
Thanks,

You could always configure them by hand if discovery doesn’t work.

cast:
  media_player:
    - host: 192.168.1.10

Thank you! I will try that. I suppose then if i have a script or automation that is supposed to go through the media player I would use the IP address then or is there a way to associate a name? here is a piece of the automation I am using courtesy of finity:

  • service: media_player.alexa_tts
    data_template:
    entity_id:
    - media_player.computer_room_dot
    - media_player.kitchen_dot
    - media_player.livingroom_dot
    #- media_player.master_bedroom_dot
    - media_player.garage_dot
    - media_player.big_room_dot

I would of course be changeing to google. I appreciate the help

If DNS works on your LAN then you can specify a name instead of iP address. This is in fact how IP networking works :slight_smile:
