Simple calibration

I have this as standard configuration for an ESP32 Devkit1 with a BMP180 breakout.

# Example configuration entry
sensor:
  - platform: bmp085
    temperature:
      name: "Outside Temperature"
    pressure:
      name: "Outside Pressure"
    update_interval: 30s

What I would like to achieve is a numeric calculation, which I can adjust as necessary, to offset or more accurately calibrate the readings displayed.

Example, for me the calculation should be something logical like

temperature = temperature(name) * Offset

This assumes the sensor offset is linear and single point is all that’s required, which I doubt, but it’s a good starting point for me.

Me being a complete n00b to yaml, anyone got a pointer for me as to coding and implementation?

My hours to dedicate to this are pretty limited, hence the question after not much rummaging.

Thanks

This section of the docs lists a number of filters you can apply to any sensor. Sensor Component — ESPHome

Fantastic, just the nudge I ws hoping for, thanks nickrout!
