BME680 gas resistance values

ESPHome

I have the BME680 from Adafruit running, and have the IAQ calculatet this way:

sensor:
  - platform: bme680
    temperature:
      name: "BME680 Temperature"
      oversampling: 16x
    pressure:
      name: "BME680 Pressure"
    humidity:
      name: "BME680 Humidity"
      id: hum
    gas_resistance:
      name: "BME680 Gas Resistance"
      id: g_res
    address: 0x77
    update_interval: 60s  
# comp_gas = log(R_gas[ohm]) + 0.04 log(Ohm)/%rh * hum[%rh]    
  - platform: template
    name: "BME680 IAQ"
    id: IAQ
    unit_of_measurement: IAQ
    lambda: 'return log(id(g_res).state) + 0.04 *  id(hum).state;'

Just use the lambda to do this simpel calculation.

Edit: I run this on a ESP32
