Example:
Scale = 0x00 (KWh)
Precision = 2
Size = 4 Bytes (KWh)
Meter Value 1 = 0x00(KWh)
Meter Value 2 = 0x01(KWh)
Meter Value 3 = 0x38(KWh)
Meter Value 4 = 0xA3(KWh)
Accumulated power consumption (KWh) = (Meter Value 2*65536) + (Meter
Value 3*256) + (Meter Value 4) = 800.35 (Kwh)
2-2-3 Clearing accumulated power consumption
Whenever re-start counting the accumulated power consumption is needed, you
can use Meter Reset Command to clear it.
Meter Reset Command:
[Command Class Meter, Meter Reset]
2-2-4 AC load Voltage (V)
When receiving Meter Get Command, it will report Meter Report Command to
the node.
Meter Get Command:
[Command Class Meter, Meter Get, Scale
=0x04(V)]
Meter Report Command:

Example:
Scale = 0x04 (V)
Precision = 1
Size = 2 (2 Bytes of V)
Meter Value 1 = 0x09(V)
Meter Value 2 = 0x01(V)
AC load Voltage = (Meter Value 1*256) +(Meter Value 2)= 230.5 (V)
2-2-5 AC load current ( I )
When receiving Meter Get Command, it will report Meter Report Command to
the node.

Meter Value 1 = 0x01(I)
Meter Value 2 = 0x21(I)
AC load current = (Meter Value 1*256) +(Meter Value 2)= 2.89 (A)
2-2-6 load power factor (PF)
When receiving Meter Get Command, it will report Meter Report Command to
the node.
