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.

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.

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

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.

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

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