    VELUX CO₂ Observed series: at 160.8s, HomeKit reported 612 ppm, bytes 28–31 were 04 F1 00 80, and the derived CO₂ code was 226. At 445.8s, 626 ppm corresponded to 65 F1 00 80, also code 226. At 730.8s, 628 ppm corresponded to 00 71 80 80, code 227. At 1015.7s, 604 ppm corresponded to 04 F2 00 80, code 228. At 1300.7s, 646 ppm corresponded to 65 70 80 80, code 225.

    The current CO₂ formula is ((byte29 & 0x7F) << 1) | (byte30 >> 7). It is strongly inversely correlated with ppm, but quantized. Byte 28 changes without changing the coarse code, yet it also repeats at different ppm values, so it is not simply the missing precision. No tested 8–20-bit window yielded exact ppm, and the remaining bytes change heavily—possibly because of counters, integrity protection, whitening, or another transform.

    Best theory: the gateway derives the precise HomeKit reading using filtering or measurement history while RF carries a coarse value—or the exact value lives in another protected field. Captures are available for anyone wishing to summon the protocol goblin. 🧌📻

    Follow-up from the VELUX CO₂ protocol mines: we sampled more. The goblin has evolved. 🧌📻

    25 minutes of synchronized RTL-SDR + HomeKit data produced 27 clean frames:

    ```text

    612 ppm → 04 F1 00 80
    626 ppm → 65 F1 00 80
    628 ppm → 00 71 80 80
    604 ppm → 04 F2 00 80
    646 ppm → 65 70 80 80

    ```

    A 9-bit field tracks CO₂ strongly—but only coarsely. The other byte repeats across different readings, so it’s probably status/counter/protection, not extra precision.

    Current theory: the sensor transmits a quantized value and the VELUX gateway calculates/filters the exact ppm shown in HomeKit. Or there’s another protected field still laughing at us.

    Captures available. Protocol archaeologists welcome. 🏺

    604 ppm → 04 F2 00 80
    646 ppm → 65 70 80 80

    ```

    A 9-bit field tracks CO₂ strongly—but only coarsely. The other byte repeats across different readings, so it’s probably status/counter/protection, not extra precision.

    Current theory: the sensor transmits a quantized value and the VELUX gateway calculates/filters the exact ppm shown in HomeKit. Or there’s another protected field still laughing at us.

    Follow-up from the VELUX CO₂ protocol mines: we sampled more. The goblin has evolved. 🧌📻

    25 minutes of synchronized RTL-SDR + HomeKit data produced 27 clean frames:
