This repo enables access to Deye Hybrid Inverters & Deye branded inverters like Sunsynk through a Python 3 library. It also provides an Add-On that can be installed in the Home Assistant OS.
This code was developed on a Sunsynk 5.5 kWh inverter.
DISCLAIMER: Use at your own risk! Especially when writing any settings.
Refer to https://sunsynk.wectrl.net/
For the Add-On you require Home Assistant OS and a RS-485 adaptor to connect to your Sunsynk inverter. Sensors are read using the Modbus protocol and sent to a MQTT server. See deployment options for examples of tested hardware.
