Reset the kilowatt-hours (kWh) of the Energy meter by a modbus/rtu command
For safety concerns, we do not provide an easy way to reset the kwh of the wifi energy meter.
(Another important reason is even if you add an energy meter with none zero kWh into IAMMETER, it will also work properly, not affect any analysis)
Considering some customers need to reset the kWh for some reason, we open the method in public here.
If you want to reset the kWh of the energy meter,you need to wire the RS485(9600/8/n/1) and send the corresponding command to it
For WEM3080(single phase energy meter) , this command will reset both forward and reverse kwh.
01 10 00 0C 00 02 04 00 00 00 00 F3 FA （reset both forward and reverse kwh in 3080）
For WEM3080T(three phase energy meter), the forward and reverse kwh need to be reset by two commands
01 10 00 63 00 02 04 00 00 00 00 B5 92 （reset the forward kwh in 3080T）
01 10 00 66 00 02 04 00 00 00 00 75 AD （reset the reverse kwh in 3080T）
