ModBus Measurement Daemon - simple reading of data from ModBus meters and grid inverters

SolarEdge Modbus data collection library

Home Assistant customcomponent for SunSpec modbus devices

DIY Arduino consumption regulator build to use excess solar power for auxiliary 'summer' heating. The solar power data are retrieved over SunSpec Modbus TCP. IoT monitoring with Blynk and local Web server.

Dynamic export control/solar curtailment of inverters for dynamic connections (CSIP-AUS/SEP2/IEEE 2030.5), fixed/zero export or negative feed-in

Monitoring Sunspec (Modbus TCP) compatible Solar Inverters

HA Custom Component to integrate data from ABB/Power-One/FIMER PV Inverters that support SunSpec Modbus (Sunspec M1, M101, M103, M160), natively or through the VSN300 wifi logger card.

Collects data from Modbus devices like SolarEdge inverters and exports it as JSON, XML or to Prometheus/InfluxDB.

An OPC UA server-backed Home Energy Management System (HEMS) for the Smart Home

Provides a http api and a cli for reading sma inverters, energy meters and plants. Supports auto discovery.

Home control libraries, console, and Web applications using REST APIs and Modbus based on ASP.NET

iotic is an IoT device manager which is dead simple to use. Its main feature is pv surplus charging of your electric vehicle.

Rust crate for accessing SunSpec compliant devices in a safe and convenient way.

Fronius Symo Hybrid battery charging/discharging limits setting with Modbus TCP

A java library to read data from my Modbus based energy devices.

ESP32 firmware that autodiscovers solar inverters over their native RS485 protocols and republishes them as MQTT/Home Assistant, Modbus TCP, REST and Prometheus

Service that publishes data from SunSpec-compliant inverters to an MQTT broker

ABB/FIMER PVI inverters - VSN300/VSN700 REST API integration for Home Assistant

ESP32 SmartMeter that reads Kaifa MA309 data, converts it to Sunspec and provides it via Modbus RTU server
