For the values in the 15025 table:

• 5900 represents the fan desired operating mode with:
  • 0 means OFF
  • 1 means AUTO
  • 10..50 represent level 1 to 5

  • 0 = OFF/unlocked,
  • 1 = ON/locked
• 5906: disables the mode and physical lock LED's.
  • 0 = OFF/leds are switched on
  • 1 = ON/leds are switched off
• 5907: value seems to be measured in ppm. Tradfri apps guidelines are:
  • n >= 86: Bad
  • 85 >= n >= 36: OK
  • n < 36 : Good
• 5908: actual fan speed from 0 (off) to 50 (max)
• 5910: Number of minutes remaining before the next filter check operation.
• 5902 and 5904 seem to be respectively the current used duration of the filter (in min) and the next check lifetime (in min).
