Severity attribute for entities

For your consideration, here’s one way to achieve your goal using existing features.

Using Manual Customization, define new attributes for the sensors that you wish to monitor. The following example adds tolerance_max and tolerance_min to three sensors.

sensor.first:
  tolerance_max: 90
  tolerance_min: 60

sensor.second:
  tolerance_max: 10
  tolerance_min: 5

sensor.third:
  tolerance_max: 200
  tolerance_min: 50

Create an automation that reports when the value of one of the three sensors is not within its tolerance levels.

alias: Out of tolerance
mode: queued
variables:
  t_max: "{{ state_attr(trigger.entity_id, 'tolerance_max') }}"
  t_min: "{{ state_attr(trigger.entity_id, 'tolerance_min') }}"
  val: "{{ trigger.to_state.state | float(0) }}"
trigger:
  - platform: state
    entity_id:
      - sensor.first
      - sensor.second
      - sensor.third
condition:
  - condition: template
    value_template: "{{ not t_min < val < t_max }}"
action:
  - service: notify.persistent_notification
    data:
      title: "{{ trigger.entity_id }} is out of tolerance."
      message: "Value: {{ val }}, Range: {{ t_min }}, {{t_max }}"
