| exhaust_temp | recuperator | Number | RO | Temperature of the air when pushed outside |
| battery_life | service | Number | RO | Remaining Air Dial Battery Level (percentage) |
| filter_life | service | Number | RO | Remaining life of filter until exchange is necessary (percentage) |
| filter_period | service | Number | RW | Number of months between filter replacements (between 3 and 12). This value affects calculation of filter_life by the unit, and might get overwritten by Air Dial or Link CC Controller. |
