Frame Type
Frame ID
Identifies the serial port data frame for the host to
correlate with a subsequent transmit status. If set to 0, no
transmit status frame will be sent out the serial port.
4 0x01
MSB 5 0x00
6 0x13
7 0xA2
64-bit address of the destination device (big endian byte
order). For unicast transmissions, set to the 64-bit
address of the destination device, or to
0x0000000000000000 to send a unicast to the
coordinator. Set to 0x000000000000FFFF for broadcast.

16-bit
16-bit address of the destination device (big endian byte
order). Set to 0xFFFE for broadcast, or if the 16-bit
address is unknown.

Frame-specific
Data
MSB 17 0x07
LSB 18 0x01
Set to the cluster ID that corresponds to the ZCL
command being sent.
0x0701 = Demand response and load control cluster ID
Cluster ID
Profile ID
MSB 19 0x01
LSB 20 0x09
Set to the profile ID supported on the device.
0x0109 = Smart Energy profile ID.
Sets the maximum number of hops a broadcast
transmission can traverse. If set to 0, the transmission
radius will be set to the network maximum hops value.

All bits must be set to 0.
Bitfield that defines the command type and other relevant
information in the ZCL command. See the ZCL
specification for details.
Data Payload
Frame Control
A sequence number used to correlate a ZCL command
with a ZCL response. (The hardware version response
will include this byte as a sequence number in the
response.) The value 0x01 was arbitrarily selected.

ZCL Frame
Header
Since the frame control "frame type" bits are 01, this byte
specifies a cluster-specific command. Command ID 0x00
in the Demand Response and Load Control cluster is a
Load Control Event command. (See Smart Energy
specification.)
