Configuring GoodWe inverter in Home Assistant

In this post we are explaining how to setup a GoodWe inverter in Home Assistant (aka hassio) with an add-on that provides direct LAN communication with the inverter.

SETUP STEPS

HACS is a community of hassio add-ons. Follow instructions here to configure HACS in hassio.

For the setup step we need to install previously a SSH add-on as explained here and then execute the following command from the shel:

wget -O - https://get.hacs.xyz | bash -

Restart hassio

Then, go to Configuration|Integrations menu and follow steps here

After HACS setup, open HACS menu

Now click on [EXPLORE AND ADD REPOSITORIES] button in the riight down corner:

Search for goodwe, select GoodWe Inverter Solar Sensor (UDP – no cloud) and click [add]

Integration component appears on page:

Restart hassio again and go to Configurations menu

Click on [ADD INTEGRATION] button in the rigth down corner

Search for goodwe

Select GoodWe Inverter and set the IP address of the inverter

NOTE: Configure your router to make a reservation for the inverter IP address. One method to know the mac address and other interesting data obtained from the inverter are explained in the troubleshooting section at the end of the post

After a while, the integration will be ready

A bunch of sensors are now ready to be used in automations

In next posts we’ll show how to made automations with these sensors.

TROUBLESHOOTING

From a computer in your network execute the following (you need python installed):

git clone https://github.com/mletenay/home-assistant-goodwe-inverter.git
cd home-assistant-goodwe-inverter/
pip3 install goodwe
python3 inverter_scan.py

Important information of the inverter is printed out:

Identified inverter model: GW5048-EM, serialNr: 9.....8

Now edit the file inverter_test.py and put the discovered IP address before:

Run the following:

python3 inverter_test.py
