GoSungrow: Home Assistant add-on for Sungrow iSolarCloud with managed dashboards

Hi everyone,

I wanted a Sungrow setup in Home Assistant that is easy to install, easy to keep running, and gives you a clean dashboard out of the box.

So I turned my fork into a proper Home Assistant add-on.

GitHub / custom repository:

Why this exists

This project is based on the original MickMake/GoSungrow work, and that reverse-engineering effort is the reason this add-on exists at all.

But in my own setup, the original project no longer worked reliably enough to be a practical Home Assistant solution. I wanted something that works cleanly with current Sungrow login behavior, Home Assistant OS, MQTT discovery, and a normal add-on workflow.

The goal of this fork is simple:

  • install it like a normal Home Assistant add-on

  • enter your iSolarCloud username and password

  • start it

  • get entities and dashboards automatically

What it does

GoSungrow:

  • logs in to Sungrow iSolarCloud

  • publishes entities to Home Assistant through MQTT discovery

  • creates a managed Overview dashboard with live energy flow and key daily charts

  • creates a managed Trends dashboard with deeper energy plots

  • works on aarch64 and amd64

Why it is easy to use

For most people, setup is basically:

  1. Install and start the Mosquitto broker add-on.

  2. Confirm the Home Assistant MQTT integration is working.

  3. Add this repository as a custom add-on repository.

  4. Install GoSungrow.

  5. Enter your gosungrow_user and gosungrow_password.

  6. Start the add-on.

That is it.

You do not need to manually configure API hosts, app keys, custom dashboard URLs, or a separate MQTT connection for a normal installation.

Requirements

  • Home Assistant with add-on support

  • working MQTT in Home Assistant

  • iSolarCloud account

  • outbound internet access from Home Assistant to iSolarCloud

Current focus of this fork

I intentionally focused this repository on one use case:

  • Home Assistant add-on first

  • clean install path

  • automatic dashboard setup

  • minimal settings for first-time users

Feedback welcome

If you have a Sungrow system and want a simpler way to get the data into Home Assistant, give it a try.

If something breaks for your particular inverter / plant / region combination, please open an issue with logs and details.

Feedback, Add-ons have been renamed to Apps several months ago.

Thanks Andreas,
this works just great. You saved me from total despair.

Hi Andreas

Thank you for your work!

I’ve some troubles with the installation of the dashboard and getting data.

I’m located in Switzerland and part of a SCC with the neighbourhood.

The log says:
