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.

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

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

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

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

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

A tokio-based SunSpec library

Networking library on top of uvw (respectively libuv). Includes http, modbus and sunspec client. Also: dns-sd / mdns.

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

emit sunspec data from modbus to MQTT

Library used for discovering and reading data from electric energy devices, like inverters and smart meters.

Reading data from your solar inverter

SunSpec domain model and use cases for Go. UNMAINTAINED

Queries SunSpec compatible solar inverters (e.g. SolarEdge) using Modbus TCP for the current solar power production, current power import and current power export as well as total energy production, import and export. It then makes theses values available to other services via Socket.IO.

ProjectEnergy32: read SolarEdge inverter values using SunSpec / Modbus TCP, publish to MQTT (Python version)

Research on SunSpec

Rust edge service that polls SunSpec Modbus inverters and streams normalized Avro data to Kafka.
