I have a number of temperature sensors that deviate from actual temperatures in the area, instead of adding more sensors, or just remembering how far off they are for automations it would be nice to be able to put in a value or numeric formula to offset the measurable values, (temp, humidity, pressure etc…)
I would be happy with a simple plus or minus number to add to the official value in the integration/device setup, but for more complex calibrations having the ability to input a formula (or a simple +1, -5) may be more advantageous for some.
