Empirical evidence shows that reasonable values are usually returned after about 1 minute.
+- **warmup_time** (*Optional*, [Time](/guides/configuration-types#time)): The sensor has a warmup period during which it returns inaccurate readings (e.g., 500ppm, 505ppm). This setting discards readings until the warmup time has elapsed (returning `NaN` during warmup). The datasheet specifies a 10-minute preheating time for full accuracy, with 90% accuracy achieved after 3 minutes. Empirical evidence shows that reasonable values are usually returned after about 1 minute. Defaults to `75s`.

 ## `hc8.calibrate` Action
 
 This [action](/automations/actions#all-actions) executes baseline calibration command on the sensor with the given ID.
 
-If you want to execute baseline calibration, the HC8 sensor must work in stable gas environment
-for at least 2 minutes and you execute this function.
+Before executing baseline calibration, ensure the HC8 sensor has been operating in a stable gas environment
+(with known CO₂ concentration) for at least 2 minutes.
+
+**Warning:** Only calibrate the sensor in a known stable environment (e.g., outdoors or in a well-ventilated room).
+Incorrect calibration will result in inaccurate readings.
