1 Phase < 100A¶
A single-phase energy meter for supplies up to 100 A. It connects to an Arduino Opta over RS485 (Modbus).
Setup¶
Set a Modbus address that is unique among the meters connected to the same Opta, as on the 3 Phase < 100A meter. If it is the only meter on the Opta, leave the address as 001.
