Compatibility

  • FIBARO Home Center 3
  • FIBARO Home Center 3 Lite 
  • Nice Yubii Home (PRO) and compatible
  • FIBARO/Nice firmware version: 5.120, or newer
  • Hoymiles HMS and HMT series microinverters via Hoymiles DTU-PRO-S controller
  • Hoymiles HM series microinverters via Hoymiles DTU-PRO Gen3 controller

Hoymiles DTU-PRO Gen3 and DTU-PRO-S controllers support Modbus TCP protocol via LAN connection, which allows direct connection of FIBARO controller and integration via the local network without the use of additional devices (NOTE: this only works for the LAN connection, Modbus TCP protocol for the WiFi connection is not supported).
The DTU-PRO Gen3 and DTU-PRO-S controller also supports Modbus RTU protocol on its RS-485 serial connector. For such integration, you need an additional Modbus RTU-TCP Gateway, which must be purchased and installed yourself. This gateway can also support other devices with the Modbus RTU protocol in parallel.
QuickApp supports up to 32 PV panels and 16 microinverters, connected to one DTU-PRO(-S) controller. One inverter, depending on the model, can support up to 4 PV panels.

How it works

The solution, in general is based on Modbus TCP communication protocol and connecting DTU-PRO(-S) controller via local network. Integration can also be done via additional Modbus RTU-TCP gateway (hardware converter) connected to DTU-PRO(-S) controller’s RS-485 serial port (via 2-wires cable).

Following Modbus RTU-TCP gateways were tested and works fine:
 • PUSR: USR-DR302, USR-DR404 i USR-W610 (www.pusr.com)
 • Waveshare: RS485 TO ETH (B), RS232/485/422 TO POE ETH (B) (www.waveshare.com/wiki)
 • Elfin: EE11A, EW11A (www.hi-flying.com)
Other gateways with same functions shall also work.

Hoymiles DTU integration is available as developer (multi-device) version implemented in the form of two QuickApps, and in a compact version in the form of a single QuickApp. The trial (demo) version is only available as the compact version.

For a direct connection (Modbus TCP via the LAN port of the DTU-PRO(-S) controller), it is highly recommended to use the compact version.

Supported functions

  • Supports for up to 16 connected microinverters and up to 32 PV panels
  • Monitors detailed information about the status of each microinverter (current production power, output voltage, total production, inverter’s temperature, day/night mode)
  • Monitors information about each connected PV panel (power and current)
  • Shows summary data on the production of the entire system: power, total and daily energy, current production power
  • Creates Energy and Power meter child devices for direct use in the Energy Panel of the Home Center controller
