Notes
Device is not reporting with decimal points precision
It's been reported by several people that this device does not report with decimal precision.
Even though the device has the option to set the number of digits after the decimal for both temperature and humidity, it does not report with decimals. So unless IKEA chooses to fix this with a firmware update, this will not work.
Pairing
Pair the sensor to Zigbee2MQTT by quickly pressing the pair button 4x to get it connected.
OTA updates
This device supports OTA updates, for more information see OTA updates.

How to use device type specific configuration
temperature_calibration: Calibrates the temperature value (absolute offset), takes into effect on next report of device. The value must be a number.temperature_precision: Number of digits after decimal point for temperature, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of0and with a with a maximum value of3humidity_calibration: Calibrates the humidity value (absolute offset), takes into effect on next report of device. The value must be a number.humidity_precision: Number of digits after decimal point for humidity, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of0and with a with a maximum value of3pm25_calibration: Calibrates the pm25 value (absolute offset), takes into effect on next report of device. The value must be a number.identify_timeout: Sets the duration of the identification procedure in seconds (i.e., how long the device would flash).The value ranges from 1 to 30 seconds (default: 3). The value must be a number with a minimum value of1and with a with a maximum value of30
Exposes
Temperature (numeric)
Measured temperature value. Value can be found in the published state on the temperature property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"temperature": ""}. It's not possible to write (/set) this value. The unit of this value is °C.
Humidity (numeric)
Measured relative humidity. Value can be found in the published state on the humidity property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"humidity": ""}. It's not possible to write (/set) this value. The unit of this value is %.
Pm25 (numeric)
Measured PM2.5 (particulate matter) concentration. Value can be found in the published state on the pm25 property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"pm25": ""}. It's not possible to write (/set) this value. The unit of this value is µg/m³.
VOC index (numeric)
Sensirion VOC index. Value can be found in the published state on the voc_index property. It's not possible to read (/get) or write (/set) this value.
Identify (enum)
Initiate device identification. Value will not be published in the state. It's not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"identify": NEW_VALUE}. The possible values are: identify.
Linkquality (numeric)
Link quality (signal strength). Value can be found in the published state on the linkquality property. It's not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.
