Hello
This is my first post on this forum , and I’d like to share my working setup for ORNO OR-WE-516 3 phase energy meter with RS485 ( modbus rtu). It works for me, so it might be useful for others.
I use this meter for my photovoltaic system metering .
sample data :
Item ‘mt_PV_curr_L3’ changed from 0.5299999713897705 to 0.5400000214576721 [ A]
Item ‘mt_PV_power_L3’ changed from 0.11400000005960464 to 0.11100000143051147 [kW]
Item ‘mt_PV_volt_L1’ changed from 235.3000030517578 to 235.39999389648438 [V]
