Huawei's solar business, branded FusionSolar, makes SUN2000 inverters, LUNA2000 batteries, smart meters, the EMMA energy management module and Smart Dongles. This page covers only that solar range, not Huawei's phones or other consumer products. Systems are monitored in Huawei's FusionSolar app and cloud, and can also be read locally over Modbus TCP or through Huawei's Northbound API.
A SUN2000 system talks to Huawei's cloud, usually through a Smart Dongle on the home network, and the FusionSolar app reads from that cloud. Local access is a separate, optional path: Modbus TCP must be switched on in the inverter or dongle settings, and the community integrations we found use it or the cloud API. We found no voice assistant or Matter link.
That suits people who want solar and battery data inside Home Assistant, Homey, evcc or similar energy software. It is weaker for plain smart home use: we found no Alexa, Google Home, Apple Home or Matter support, local Modbus allows only one client at a time, and some settings need an installer account.

The main app, published by Huawei Digital Power Technologies. Owners and installers monitor plant status, real-time and historical data, energy flow, yield and revenue. Installers also use it for on-site commissioning, parameter setting, log export and upgrades by connecting to an inverter or SmartLogger. It works alongside Huawei's SmartPVMS web portal. Huawei says Huawei phones get it from AppGallery and other Android phones through a QR code and browser download. A Google Play listing for the same name appeared in search results, but we could not open it to confirm the publisher.
A local maintenance app from Huawei Digital Power Technologies for installers. It connects to an inverter or SmartLogger over Bluetooth for status, alarms, parameter configuration, log download and firmware upgrades from a file on the phone. The listing shows a low rating (1.6 out of 5 from 11 ratings) with reviews mentioning crashes and connection problems. We could not confirm an Android store link.

Connection
Wi-Fi and Ethernet (Smart Dongle)
Yes
Third-party documentation describes a Huawei Smart Dongle (SDongleA-05 Wi-Fi or SDongle FE Ethernet, and a 4G version) in the inverter's USB port, which puts the system on the home network and carries data to Huawei's cloud. The inverter also has its own access point, SUN2000-<serial number>, at 192.168.200.1. Huawei's commissioning guide lists a 2.4 GHz router with WPA or WPA2 as a requirement.
Inverters send data to Huawei's cloud, which the FusionSolar app and portal read. Integrations that use the cloud go through the Northbound API or a kiosk URL rather than the local network.
Local reads work over Modbus TCP, typically port 502 or 6607, or over RS485 with a USB adapter on the inverter's COM port. Modbus TCP must be enabled first, and some settings need the installer account. Only one Modbus client can connect at a time, so a second tool can block the first. We found these details on community and third-party pages, not on a Huawei page.
The SUN2000 installer app connects to an inverter or SmartLogger over Bluetooth for local maintenance. We found no Bluetooth link for third-party platforms.
No built-in integration found, though Home Assistant's integrations page was not opened to be sure. Two custom integrations install through HACS. Huawei Solar (by wlcrs) reads SUN2000 inverters, batteries, meters and optimizers locally over Modbus TCP or serial and polls every 30 seconds by default. FusionSolar (by tijsverkoyen) uses the Northbound API, which needs an account created by an installer, or a kiosk URL that must be renewed each year. Neither page states an affiliation with Huawei.
Huawei FusionSolar Manager is a community app by an independent developer, not Athom. It supports SUN2000, LUNA2000, meters, EMMA, SDongle A and an EV charger over Kiosk, OpenAPI, Modbus TCP and OCPP. It lists Homey Pro, Homey Cloud and Self-Hosted Server, but marks several Modbus and EMMA drivers as needing a Homey Bridge. The page we opened was a test version that warns it is unreviewed.
No dedicated Huawei binding found. A community thread describes reading SUN2000 data with openHAB's generic Modbus binding over TCP via the Smart Dongle.
Not searched in depth, so no plugin was confirmed either way.

Community
Other energy and automation software documents SUN2000 support. evcc reads it over Modbus TCP or RS485. TapHome ships a template that covers LUNA2000 battery state of charge, and recommends the Smart Dongle so it can run beside FusionSolar. nymea connects through the Smart Dongle (software SP133 or later) with Modbus TCP set to full access.
Huawei publishes a SmartPVMS Northbound API Reference (version 24.5.0, updated July 2024) with Basic APIs and Control APIs. The page we opened lists only section headings, so access rules and rate limits come from third-party notes: the Home Assistant FusionSolar integration says an installer must create the account, that rate limits are strict and that each account allows one login session.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
