Calcuate increment value change for a sensor

Configuration

Hello,

Can someone suggest a route how to calculate the incremental change in value for a sensor?

Say sensor_x was just updated to 90 from previous value of 88. So the increment value I am looking for is 2.

Thanks

You can use a template… Exactly how you need to set it up will vary depending on where and how you plan on using the value.

Here’s an example creating a sensor that holds the value:

template:
  - trigger:
      - platform: state
        entity_id: sensor.x
    sensor:
      - name: Sensor X Increment Value
        state: "{{ trigger.to_state.state | int - trigger.from_state.state | int }}"

If you share more information about your use case, we can probably give you an answer that is appropriate for what you are trying to do.
