This repository provides a Home Assistant custom component (solax_modbus) that integrates solar inverters from multiple brands (SolaX, Growatt, Sofar, Solis, SRNE, etc.) via Modbus TCP/serial/RTU. It exposes real-time sensor data, battery status, energy totals, and control entities (numbers, selects, switches, buttons, time) into Home Assistant. The component features a plugin architecture where each inverter brand has its own module defining entity descriptions, register maps, and inverter detection logic. It includes an energy dashboard virtual device that aggregates grid, solar, battery, and home consumption for the native Home Assistant Energy Dashboard. Advanced capabilities include remote power control (VPP modes), autorepeat loops, parallel master-slave support, and automatic bad-register quarantine. The codebase is well-tested with unit tests and CI/CD, but suffers from some duplication across plugins and hardcoded register maps.
This repository is a Home Assistant custom integration for communicating with Solarman Stick Loggers to monitor and control solar inverters. It uses Modbus TCP/RTU to read/write inverter registers, exposing the data as Home Assistant entities (sensors, switches, etc.). The integration includes a device discovery mechanism via UDP broadcast, a configuration flow for setup, and a coordinator for periodic data updates. It also provides services for arbitrary Modbus register operations. The inverter definitions are stored in YAML files that specify the register mappings and sensor configurations for various inverter models.
