READ_EIN
Code: 0x86, block read. Value after reset: 0x06, 0x0000, 0x00, 0x000000.

Value
0x06
0x0000
Description
Always reads as 0x06, the number of data bytes that the block read command
should expect to read.
Energy accumulator value in direct format. Byte 2 is the high byte, and Byte 1 is the
low byte. Internally, the energy accumulator is a 24-bit value, but only the most
significant 16 bits are returned with this command. Use the READ_EIN_EXT
command to access the nontruncated version.

Rollover count
Sample count
0x00
0x000000
Number of times that the energy count has rolled over from 0x7FFF to 0x0000. This
is a straight 8-bit binary value.
This is the total number of PIN samples acquired and accumulated in the energy
count accumulator. Byte 6 is the high byte, Byte 5 is the middle byte, and Byte 4 is
the low byte. This is a straight 24-bit binary value.
READ_VIN
Code: 0x88, read word. Value after reset: 0x0000.
