Energomera CLI

Energomera example CLI application written in Go

Usage

To build it:

git clone https://github.com/peak-load/energomera-cli.git
cd energomera-cli
go get -v
go build 

To configure it edit config.json file located in the same directory

{
     "Port": "/dev/serial0",
     "SleepInterval": 500,
     "Counters" : ["000001","000002"]
}

• Port - specify your port connected to rs-485 bus. Depends on your adapter model or OS (I'm using on Linux under RPi3) port can be different e.g. /dev/ttyS0 or /dev/USB0
• SleepInterval - in milliseconds, can be adjusted if you are getting errors due to long read time
• Counters - specify your electricity meter unique IDs. ID needs to be set beforehand using windows based utiliy as described in manual here

To run it (with sample output):
