- Unidirectional. Bulbs never send packets.
- Always 7 bytes.
The packets are structured as follows:
| Field | Length | Notes |
|---|---|---|
| 1 | 1 byte | Always 0x5A |
| 2 | 2 bytes | Device ID |
| 3 | 1 byte | Group ID |
| 4 | 1 byte | Command (listed in code here) |
| 5 | 1 byte | Sequence num (unused?) |
| 6 | 1 byte | Sequence num (usually ≠ to field #5) |
- Brightness and temperature can only be controlled by increase and decrease commands.
