Huawei FusionSolar Manager
Take control of your solar energy — via Kiosk, OpenAPI or Modbus.
The app supports three independent connection methods: the public Kiosk URL (no account required), the official FusionSolar Northbound API, and direct Modbus TCP communication with the SUN2000 inverter, LUNA2000 battery and DTSU666 smart meter.
Each device type appears separately in Homey. The SUN2000 inverter reports solar power, PV string voltages and currents, daily and total energy yield. The LUNA2000 battery shows state of charge, charge and discharge power, and supports direct control of the storage working mode. The DTSU666 smart meter tracks grid import and export energy across all three phases and integrates with the Homey Energy Dashboard as a P1 meter. The Kiosk and OpenAPI devices provide plant-level energy data including daily, monthly and yearly totals.
All values are available in Homey Insights and Flows — for example to switch on a heat pump when grid export starts, or to limit loads when battery state of charge drops below a threshold.

Set above rated power × 1.1 to effectively disable the limit. Works WITHOUT a Smart Power Sensor.
Inverter SUN 2000 (Modbus)
Remove inverter output limit (no cap)
Resets both output limits to 'no cap': writes rated power × 1.1 to register 40126 and 100 % to register 40125. Use this to fully remove a previously set output limit and let the inverter run at its natural maximum.

Limit inverter output to Percentage (%) %
Sets the maximum AC output as a percentage of rated power (register 40125). This is a ceiling, not a setpoint — actual production follows the natural PV level when sun is weaker, and is only throttled when sun would otherwise produce more. Example on a 4 kW inverter: 50 % = 2 kW cap. Set to 0 to fully shut down, 100 to remove the limit. Works WITHOUT a Smart Power Sensor.

새로운 기능
버전 1.1.47 — Improved diagnostics: all 8 Modbus drivers now log a 'Poll OK' line with key values (SoC, power, grid, etc.) after every successful poll — makes it easy to confirm data is flowing from the log. Added a watchdog in each driver that detects and resets a stuck _fetchInProgress flag after 2 minutes, preventing silent polling stalls when a TCP connection hangs.
