This release is a pre-release and may not be stable for production use.
sigenergy2mqtt is a bridge between the Modbus interface of the Sigenergy energy system and the MQTT lightweight publish/subscribe messaging protocol.
In addition, sigenergy2mqtt has several optional features:
- It can auto-discover Sigenergy devices and their device IDs without having to specify the host IP address.
- It can publish the appropriate messages to allow Home Assistant to automatically discover the Sigenergy devices, simplifying Home Assistant configuration.
- Production and consumption data can automatically be uploaded to PVOutput.
- It can directly publish the Modbus data to an InfluxDB (v1/2) time series database for long-term storage and analysis.
Pre-requisites
- Sigenergy ESS or PV Inverter, with Modbus-TCP enabled by your installer or through the mySigen app
- MQTT broker such as Mosquitto, either standalone or installed as an app to Home Assistant
Installation
Follow the installation guides for supported environments:
Configuration
When parsing configuration options, sigenergy2mqtt looks at the configuration sources in the following order:
This means, for example, that the options specified in the configuration file can be overridden by environment variables and command line options.
The combined reference for CLI flags, environment variables, and YAML configuration keys can be found here.
1 Not applicable to the Home Assistant App

Disclaimer
sigenergy2mqtt was developed for my own use, and as such has only been tested in my single-phase environment without AC or DC chargers, although I have developed a testing environment in software that emulates the chargers and three phase implementations. If you find a problem, please raise an issue.
