Arduino library for reading BEL single-phase energy meters over a serial line.
The BelWattmeter Arduino library parses the framed serial protocol of BEL single-phase energy meters (9600 baud) and decodes voltage, current, instantaneous power and cumulative consumption. It handles frame synchronization, byte unescaping and CRC validation, rejects out-of-range readings, and running-averages voltage, current and power between reads. The serial stream is injected via the constructor, so any HardwareSerial or SoftwareSerial port can be used. Ideal for photovoltaic and appliance energy monitoring.
