TGnet Zigbee protocol
I settled on channel 16 at 9600 baud for the initial control netwrok.
Protocol is as follows:
| 0x7f | Pac synch 1 |
| 0xfe | Pac synch 2 |
| 0xdd | Destination address |
| 0xss | Source address |
| 0xnn | Packet Length |
| 0xop | Op code |
| 0xxx - 0xyy | data |
| 0xcc | CRC LSD byte |
| 0xcc | CRC MSD byte |
- Packet length is entire length including 2 synch bytes and 2 crc bytes
Address assignments:
| Bonnard Master | 0x01 |
| Burbank grow box | 0x02 |
| Burbank garage status | 0x03 |
