Python software for SuperWatt VM II 3KW/5KW

Primary LanguageCSS

Welcome to PimpMySuperWatt repository

Overview

What is it ?

This little software allows you to retrieve parameters and real-time status of an inverter. Compatible with superWatt VM2 inverter also knows Voltronic Axpert VMII (3K/5K).

It's look like this:

SuperWatt-VM2

This inverter contains 2 ports for communication (USB and Serial). This program works (for the moment) with USB cable.

What do you need ?

  • Raspberry or linux compatible hardware, and an usb cable.
  • Java for gradle dependencies resolutions.
  • Python 3.7.3 (no guarantee that others versions works, viva Python !)

How to install/launch

git clone https://github.com/coxifred/pimpMySuperWatt.git
cd pimpMySuperWatt
./start.sh or ./debug.sh

output:

  • Note 2: A log is created under /tmp and named superwatt.log
  • Note 3: stop.sh to stop it.

Docker installation:

Create your own configuration:

- /superwatt.json
- /solarposition.json

Create this docker compose file:

version: "2"
services:
"pimpmysuperwatt":
  privileged: true
  image: "coxifred/pimpmysuperwatt"
  container_name: "pimpmysuperwatt"
  restart: always
  ports:
    - "61000:60000"
  volumes:
    - /superwatt.json:/superwatt.json
    - /solarPosition.json:/plugins/solarPosition/solarPosition.json
  devices:
    - /dev/ttyUSB0:/dev/ttyUSB0

Then simply run:

docker-compose up -d

Should be running under http://<your_host>:61000
