The binary protocol is used by connecting to TCP port 6001 on uscv2.naviensmartcontrol.com.
- Initial Connection Request
- State Request
- Device Control Request
- Trend Sample Request
- Trend Monthly Request
- Trend Yearly Request
- Channel Information Response
- State Response

- Trend Monthly Response
- Trend Yearly Response
Upon initial connection, a request containing the authenticated username
Example
00000000 75 73 65 72 6e 61 6d 65 24 69 50 68 6f 6e 65 31 username$iPhone1
00000010 2e 30 24 31 32 33 34 35 36 37 38 39 31 32 33 34 .0$1234567891234
00000020 35 36 37 567
Upon successfully submission of the Initial Connection Request, the binary protocol will respond with a Channel Information Response such as the following
00000000 XX XX XX XX XX XX XX XX 01 01 0e 00 04 01 00 00
00000010 01 00 00 00 00 00 01 00 00 02 02 00 00 01 00 00
00000020 00 00 00 01 00 00 02 03 01 01 02 62 b6 20 20 03
00000030 01 00 00 01
Of this, the first 12 bytes are the Common Response Header consisting of the following
Description: An 8 byte unique ID used in all requests and responses. The first 6 bytes are the NaviLink's MAC address
Example: 01 02 03 04 05 06 07 08 (Denoted as XX XX XX XX XX XX XX XX in the sample capture above)
Description: A one byte country code designation
Example: 01
Description: A one byte ID identifying the message type (as specified in the ControlType enum)
Example: 01 corresponding with the ControlType.CHANNEL_INFOMATION enum
Description: A one byte value of the software version major number
Example: 0e = 14 dec
Description: A one byte value of the software version minor number
Example: 00 = 0 dec
The rest of the Channel Information Response starts at array position 12 (byte 13)

operationDeviceNumber = 01 This changes to 0 when the unit is not actively running. This is also used to compute stats for cascaded devices

gasInstantUse = (b3 & 0xFF) + (22 & 0xFF) * 256 = 0xB3 + (0x22 * 256) = 179 + 8704 = 8883 (This is converted from kilocalories in the app by 8883 * 3.968 = 35,247.744 and rounded to 35,247.7 BTU. If converted accurately, should actually be 35,227.02 BTU)
gasAccumulatedUse = c7 40 00 00 treat as little endian and convert to int = 16583 (This is converted from m^3/10 in the app by 16583 * 35.314667 / 10.0 = 58,562.3122861 and rounded to 58562.3 ft^3)

Upon receiving a properly formed Device Control Request, the protocol will respond with a State Response showing the updated state.
