AlphaESS systems connect to the home network by cable (LAN) or Wi-Fi and report to AlphaESS's cloud. There is an official Open API for reading and controlling a registered system, and the inverter also exposes Modbus for local access, which an installer may need to enable. Most smart home integrations we found use one of those two routes.
That suits people who want battery and solar data inside Home Assistant, Homey or MQTT-based setups, especially with local Modbus control. It is weaker for voice assistants and mainstream ecosystems: we found no Alexa, Google Home, Apple Home or Matter support, and the Home Assistant options are community projects rather than a built-in integration.

The main app for owners of an AlphaESS system. It shows live solar generation, consumption and battery energy, and covers time-based charge and discharge schedules, force charge or discharge, dynamic tariff charts in European regions, Peak Shaving, Storm Guard, virtual power plant status, EV charger and generator tracking, and home screen widgets. Some features depend on the device model. Published by Alpha ESS Co., Ltd.

| Platform | Status | What it means | Sources |
|---|---|---|---|
| Connection | |||
| LAN and Wi-Fi | Yes | AlphaESS's quick-start guide says the app supports a wired network (LAN) or Wi-Fi and recommends a stable home network. Systems report to the AlphaCloud platform, which the company describes as supporting remote troubleshooting and upgrades. | AlphaESS app manual AlphaESS global brochure (PDF) |
| Modbus (local) | Yes | Local Modbus is used by several community projects. A Homey app lists Modbus TCP on port 502 with address 85 by default and says the installer may need to enable it. A separate hardware project reads the inverter over RS485 through the CAN/RS485 RJ45 port and follows version 1.23 of AlphaESS's Modbus documentation. We could not find that document published by AlphaESS itself. | Homey Modbus app thread Alpha2MQTT |

| Home Assistant | Community | We found no built-in integration, though we could not open Home Assistant's integrations page to be sure. Community options include a HACS integration that uses the official Open API and can optionally read a local inverter, and a local Modbus TCP integration for SMILE-M5, SMILE5, SMILE-G3, SMILE-Hi and SMILE-B3 series that states it is not affiliated with AlphaESS and writes directly to inverter registers. | homeassistant-alphaESS ha-alphaess-modbus Home Assistant community thread |
| Homey | Official | AlphaESS publishes an app on the Homey App Store (author page AlphaESS Official), and Homey announced it as an official app. It covers all AlphaESS home batteries, adds charge level and energy data to Homey Energy, and supports Flows for charging and discharging. It connects through AlphaESS's cloud with your AlphaESS login. The store page lists Homey Cloud, Homey Pro, Homey Pro mini and Self-Hosted Server but also says a Homey Bridge is required, and we could not resolve which applies. Two community apps also exist: one using the Open API or local Modbus, and one that is local Modbus on Homey Pro only. | Homey app page Homey news Community app (Open API and Modbus) Community app (Modbus, Pro) |

| AlphaESS Open API | Official | AlphaESS runs a developer portal at open.alphaess.com. You register for a free account, add your battery or inverter by serial number and check code, and use the AppID and AppSecret to call the API. Community libraries and the Home Assistant integration describe it as the official Open API and wrap around 19 documented endpoints. We did not open the portal itself. | alphaessopenapi library homeassistant-alphaESS |

Yes, through a community-built integration. We found no built-in integration, though we could not open Home Assistant's integrations page to be sure.
