The problem

Context

I have a sensor group that sums up all my tracked power sensors at home.
Every child of this group is a numerical sensor with a device_class set to power and a unit set to W.

Here is a small analysis of this group:

CleanShot 2024-06-20 at 12 09 38

Here is the sensor. You can see its state_class: measurement, device_class: power and unit_of_measurement: W

Here are the details of its child, I used a small template to extract everything if it is needed:

{% set childs = ['sensor.prise_frigo_power','sensor.prise_media_center_power','sensor.prise_lave_vaisselle_power','sensor.doorbell_power','sensor.alexa_power','sensor.prise_server_power','sensor.prise_bureau_power','sensor.machine_a_laver_power','sensor.plaques_a_induction_power','sensor.chargeur_tesla_power','sensor.four_power','sensor.puissance_simulee_lumiere','sensor.sonos_chambre_power','sensor.sonos_chambre_marilou_power','sensor.sonos_salle_de_douche_power'] %}
{% for state in states -%}
  {%- if state.entity_id in childs -%}
    {{ state.entity_id }}:
    {{state.attributes}}
  {% endif -%}
{%- endfor %}

TL;DR: Every child also have a state_class: measurement, device_class: power and unit_of_measurement: W

The problem

Two times I noticed that the group sensor lost its state_class, device_class, and unit_of_measurement.

It becomes an "untyped" sensor:

I lose the history graph:

Root cause.

I tried many things to understand where it was coming from. but I did not manage to find out for now.

Here is what I tried:

Is it because a child becomes unavailable temporarily? ... NO:
