Struct DeviceStatus 

pub struct DeviceStatus(/* private fields */);

Device status register, decoded into individual flags.

Each accessor returns a single status bit. Error flags are sticky — they stay set until cleared (see read_and_clear_device_status or a reset). The available flags are:

• speed_warning — fan speed is outside the target range.
• co2_1_error, co2_2_error — CO₂ sensor errors.
• pm_error — particulate-matter sensor error.
• hcho_error — formaldehyde sensor error.
• gas_error — VOC/NOx gas sensor error.
• rh_t_error — humidity/temperature sensor error.
• fan_error — fan is mechanically blocked or broken.
