Groups and DRY problem

Here is my groups.yaml
I repeat myself for displaying the sensors (the red circle ones on top of each page, BTW how it’s named in hass ?) :

    - sun.sun
    - device_tracker.chromebook
    - device_tracker.chromebook_touch
    - device_tracker.lgg3
    - device_tracker.oneplus
    - device_tracker.marco_oneplus
    - sensor.yr_symbol    

in each group … so 3 times ;-(

if I put them in a group, they are displayed in a box likes switchs/lights one …
How can I do, to not repeat my self here ?

Thanks in advance

not sure I had to do the same for each of my “tabs” / groups.

this is a known limitation of the current ui.

I’ve tryed with anchors/reference yaml : but no louck ;-(

BTW, is there a way to decide if a thing (think sensor/state/switch/…) is displayed at the top in a red circle, or as a line in a box ?

top circled sensor is listed straight under a view. To have it displayed as a line, you need to add it to a group first, then you list the group under the view, e.g.

default_view:
  view: yes
  icon: mdi:home
  entities:
    - device_tracker.lolo
    - device_tracker.div
    - sensor.dark_sky_temperature
    - sensor.dark_sky_humidity
    - sensor.dark_sky_overnight_low_temperature
    - sensor.dark_sky_daytime_high_temperature
    - sensor.pws_precip_1d
    - sensor.home_to_verint
    - sensor.lolo_to_home
    - sensor.sunset_time
    - group.alerts
    - group.all_alerts
    - group.scenes
    - group.dates
    - group.Weather
    - group.Vacuum
    - group.rpisensors
