Important Info

EDGE goes to full development mode - will be rewritten from scratch

The addon is in maintenance mode. This is FOSS (Free Open Source Software) and based on reverse engineering so it might not work always as expected. What is more due to techical dept present implementation loose possibility to add new features. This means that it requires rewriting from scratch. Without support from the community it is not predicted to be ready soon.

HoyMiles Solar Data Gateway Add-on

Application to read Hoymiles Gateway Solar Data using unofficial API

I developed this program to integrate my solar system data to Home Assistant Application through an add-on.

Now, Cosik is helping too.

Instructions

Home Assistant add-on instructions

There are three app versions that you can choose from:

1 - The Old Stable Version

2 - The Edge Version

3 - The Stable Version

My solar panels communicate with the internet using a DTU-W100 gateway.

But it will probably work with any device that uses the global.hoymiles.com Website. It was tested with DTU-PRO also.

Standalone running - short info

You could also use the application without using Home Assistant. You just need a machine that runs Python3. It's based on mqtt messages, so could be send from any device to MQTT Broker.

Before run, you need to install: https://github.com/eclipse/paho.mqtt.python and https://github.com/psf/requests

git clone https://github.com/dmslabsbr/hoymiles.git
cd hoymiles
python3 -m venv ./hoymiles/
source ./bin/activate
pip3 install paho-mqtt==1.6.1
pip3 install requests
pip3 install python-dateutil

Configuration:

UI is not working and could show "Bad Gateway" which is normal and expected.

Add-on is designed to use MQTT messages to send data to the Home Assistant instance. By default credentials and server name are taken from Home Assistant. If you use another broker or use your own one it is required to make external and fill server and credentials for connection.

To get it properly working you also have to pass credentials for the Hoymiles Cloud access and your plant ID.

If everything is set up correctly new MQTT entities will be visible on HA.

Supported devies

So far it is confirmed that the addon supports these Hoymiles devices:

• micro inverters
• standard inverters
• energy meters
• bms (with some restrictions) - edge version with details
• batteries (with some restrictions) - edge version with details
• multiple instalattions - edge version

PS:

I invite everyone to help in the development of this tool.
