Energomera protocol encoder / decoder package

This Go package is fully based on Python code which is used to encode and decode Energomera protocol messages,
which can be used to communicate with electricity meter(s) over rs-485 protocol.

For more information check the source code documentation.

Projects using energomera package

• CLI example application for getting data https://github.com/peak-load/energomera-cli
• Simple server that recieves data from electricity meter (multiple devices on same bus supported) and exports them via HTTP for Prometheus consumption https://github.com/peak-load/energomera_exporter

Usage / available functions

import (
     "github.com/peak-load/energomera"
)

Package provides two functions:

• energomera.DataDecode(sdata []byte) (msg map[string]string)
• energomera.DataEncode(msg map[string]string) (sdata []byte)

Functions

func DataDecode

func DataDecode(sdata []byte) (msg map[string]string)

Energomera data decoder is used to decode message received from bus

func DataEncode

func DataEncode(msg map[string]string) (sdata []byte)

Energomera data encoder is used to encode data which will be sent over bus
