Convert sensor value from negative to positive value

Configuration
#1

Hi,

Beginner here…

I have a energy meter thats reads the actual power of my solar panels. However this value is negative. How can I convert this to a positive value?

I have tried the following in configuration.yaml

template:
  - sensor:
      - name: Actual solar power - Dak
        unit_of_measurement: "kWh"
        state: "{{ states ('Solar meter dak (5c2faf0e37dc) Active power') | int *-1}}"

What am I doing wrong?

Thanks

Let’s assume your energy meter is:

sensor.solar_meter_5c2faf0e37dc

You can create a Template Sensor to convert the value of sensor.solar_meter_5c2faf0e37dc to a positive value using the abs filter:

template:
  - sensor:
      - name: Actual solar power - Dak
        unit_of_measurement: "kWh"
        state: "{{ states('sensor.solar_meter_5c2faf0e37dc') | int(0) | abs }}"
