MH-Z19 CO_2 and Temperature Sensor — ESPHome

automatic_baseline_calibration (Optional, boolean): MH-Z19 has automatic calibration procedure. The automatic calibration cycle is every 24 hours after powered on. Set this value to false to disable ABC on boot (it’s better if you use sensor indoor). Set this value to true to enable ABC on boot. Doesn’t send calibration command if not set (default sensor logic will be used).
