Automation with a trigger on a change of a numerical value?

Configuration

I thought it would be simple, but I am lost now… ;-).

I want to trigger an automation on the change of a numerical value of a device. It is a value that changes a few times per month.
But I cannot find how to do it. All triggers only seem to work when a numerical value is above of below a certain value.
I am missing something that would trigger a change of a numerical value?

For your info: it is this device: Wi-Fi P1 Meter (HWE-P1) from this integration: https://www.home-assistant.io/integrations/homewizard

Just use a normal state trigger, not numeric state. It will trigger on any change to any value (unless you tell it not to).

e.g.

This will trigger on all changes from one valid state to another:

triggers:
  - trigger: state
    entity_id: sensor.foobar
    not_to:
      - unknown
      - unavailable
    not_from:
      - unknown
      - unavailable

This will trigger on all changes including to/from unavailable/unknown and changes to the sensor’s attributes:

triggers:
  - trigger: state
    entity_id: sensor.foobar

This will trigger on all changes including to/from unavailable/unknown but ignore attribute changes:

triggers:
  - trigger: state
    entity_id: sensor.foobar
    to: ~

OK: my ‘issue’ was on a numerical value. I was expecting the numerical entities would only work ‘as numerical’ entities…: I learned from the feedback from @Mayhem_SWE the also work on the ‘state’ related triggers.
