Config Warning Lights.yaml

Hi,
Since I updated to Hass.io 0.88, I frequently receive a notification with a configuration warning message.

Warning

Here is my lights.yaml file. I don’t see where is the error. Line 27 is the line just before “-platform: group”

- platform: yeelight
  devices:
    192.168.0.29:
      name: Lampe Bureau
      transition: 350
      use_music_mode: false
      save_on_change: false
    192.168.0.28:
      name: Lampadaire papier 1
      transition: 350
      use_music_mode: false
      save_on_change: false
    192.168.0.20:
      name: Lampadaire papier 2
      transition: 350
      use_music_mode: false
      save_on_change: false
    192.168.0.30:
      name: Lampe TV
      transition: 350
      use_music_mode: false
      save_on_change: false
    192.168.0.31:
      name: Lampe Chambre
      transition: 350
      use_music_mode: false
      save_on_change: false
- platform: group
  name: Groupe Salon
  hidden: true
  entities:
    - light.lampe_bureau
    - light.lampadaire_papier_1
    - light.lampadaire_papier_2
    - light.lampe_tv

What could be the issue ? Is “-platform: group” still allowed in hassio 0.88 ?

Thanks for your help

hidden is not a valid option for group.

I think under group, “hidden: true” should be “view: false” I do not see hidden listed as valid except in some possibly old example.

Yes, that’s it :slight_smile: It was so obvious, I didn’t see the error.
Thank you all !
