March 2020 UPDATE:
Project is now finally supports multiple architectures on Docker Hub, so users should not need to manually build the image, and can just run a docker pull for most common devices (such as arm7/8, x86_64 etc).
NB Please read the readme, you may need to change your
mqtt.json files to suit your environment.
Hi all, just thought I’d share this one incase it’s useful for someone else out there…
For anyone who’s picked up one of those cheap Voltronic, Axpert, Mppsolar, PIP, Voltacon, Effekta, and other branded OEM Inverters I’ve got a Docker based solution that can be run on a lightweight & cheap SBC (Such as an Orange or Raspberry PI) allowing you to interface with them finally with ease (the bundled Java app they give you “Watchpower” is a pile of S$$T and unreliable at the best of times)…
For those unsure, this is what the Inverters look like, there are loads on Ebay for cheap
It works by both pull monitoring data (Via the RS232 or USB port on the Inverter) and sending to Home Assistant via MQTT, as well as actually programatically receiving commands (again via MQTT) to change the configuration of the Inverter on the fly - Depending on various automations you might setup (such as ‘only charge batteries off solar during the day’, then ‘charge batteries off the grid’ at night time after midnight when the price of power is cheaper) etc…
Enough blabber - Here’s the links for anyone who might be interested:
- Github: https://github.com/ned-kelly/docker-voltronic-homeassistant
- Docker Image: https://hub.docker.com/r/bushrangers/ha-voltronic-mqtt/ - Read Github Readme File 1st
Hopefully this makes someone else’s life a bit easier also
