Is it possible to retrieve a value, in this case a reading of the temperature via mqtt, and then adjust the actual reading so the the displayed value is the temp -8.
- name: "SN3 Temperature"
state_topic: "bruh/sensornode3"
unit_of_measurement: "°F"
value_template: "{{ value_json.temperature | round(1) }}"
So basically in this case I would need SN3 Temperature = SN3 Temperature -8 in order to display the adjusted or corrected value. Everything else works just fine.
