Chapter 4 SHD2110/3110 Programming

4.2.3.3 Meter Report Period (SHD3110 only)

If the Meter Report is set to 30 seconds, the SHD2110/3110 will report its instant power consumption Z-Wave Controller in every 30 seconds. The maximum interval to report its instant power consumption is 9 hours (10s*3240/3600=9hr).

4.2.4 Meter Command Class

The SHD2110/3110 will report its instant or accumulated power consumption to the Z-Wave Controller. If the calculation of accumulated power consumption is needed, the Z-Wave Controller needs to send Meter Reset Command to the SHD2110/3110, enabling it to reset.

4.2.4.1 Instant Power Consumption of Module

When the SHD2110/3110 receives Meter Get Command, it will send the Meter Report Command to Grouping 1.

The following parameters are used in this example:

Meter Value 1 = 0x01(W)

Meter Value 2 = 0xF4(W)

Meter (W) = Meter Value 1*256 + Meter Value 2 = 500W

Meter Get Command

[Command Class Meter, Meter Get, Scale =0x02(W)]

Meter Report Command

[Command Class Meter, Meter Report, Rate

Type+Meter Type, Precision+Scale+Size, Meter Value 1, Meter Value 2]

4.2.4.2 Accumulated Power Consumption (KW/h)

When the SHD2110/3110 receives Meter Get Command, it will send the Meter Report Command to Grouping 1.

The following parameters are used in this example:

Scale = 0x00 (KWh)

Precision = 1

Size = 4 Bytes (KW/h)

Meter Value 1 = 0x00(W)

Meter Value 2 = 0x01(W)

Meter Value 3 = 0x11(W)

Meter Value 4 = 0x70(W)
