Question about turning the display off an the second button to reset the baseline of the voc sensor about iaq_board HOT 3 CLOSED

Thanks a lot.
I found this for turning an OLED Display off

lambda: |-
          it.fill(COLOR_OFF);

from iaq_board.

Hi,

Here is the code to turn off the LEDs, it's raw C++ included with lambda. I couldn't find any other way although I am sure there is more elegant way to do it.
https://github.com/nkitanov/iaq_board/blob/master/firmware/includes/brightness.yaml

For the calibration of CO2 sensor (I think you are speaking for it and not VOC sensor, as VOC sensor baseline cannot be externally calibrated, it's hardcoded) here is the code, it's just a switch which executes calibration:

switch:
  - platform: template
    name: "CO2 Sensor Zero Calibration"
    turn_on_action:
      - mhz19.calibrate_zero: mh_sensor
      - switch.turn_off: co2_cal
    id: co2_cal

from iaq_board.

Ah, nice, this can be used also in the code instead of decreasing the brightness as I do it in a dumb way.
