* Advanced capacity depends on RS485 wiring and polling interval.

Where it fits

One gateway, four practical jobs in the panel.

Pick the firmware role that matches what’s actually being connected.

CAN-to-Ethernet for APEX

Bridges SmartAPEX CAN-BUS devices to Ethernet for discovery, configuration and control — the Standard V40 role.

HVAC integration

Connects HVAC systems such as Daikin, Intesis, CoolMaster and similar gateways over Modbus.

Modbus power meters

Adds RS485 Modbus energy / power meters to the network through the Modbus Bridge role.

RS485 electric curtains

Controls supported RS485 curtain motors through the MiCURTAIN Bridge role and QuickApp.

Select the correct firmware role

One gateway, three mutually exclusive jobs.

The hardware is shared by three firmware roles, but only one role can run at a time. Installing a new role replaces the current role.

Role 01

Standard V40

Normal SmartAPEX CAN, built-in Modbus/HVAC, templates and full gateway services.

Use when: the installation needs normal SmartAPEX CAN discovery, configuration, bindings, built-in Modbus points, HVAC mapping or full gateway services.

Role 02

Modbus Bridge

Transparent Modbus TCP-to-RTU for Fibaro/Yubii or another Modbus TCP client.

Use when: the external client owns the Modbus register logic and needs transparent TCP-to-RTU access.

Role 03

MiCURTAIN Bridge

Control supported RS485 curtain motors through the supplied QuickApp.

Use when: connected RS485 devices are supported curtain motors and Fibaro/Yubii must control Up, Down, Stop and target position.

Installation requirement	Firmware role	Current package
Normal SmartAPEX CAN, built-in Modbus/HVAC and full gateway services	Standard Mini IP V40	MINI_IP_vX.XXX.bin
External Modbus TCP client to RS485 meters or slaves	Mini IP Modbus Bridge	MINI_IP_MODBUS_BRIDGE_vX.XXX.bin
Supported RS485 curtain motors controlled by Fibaro/Yubii	Mini IP MiCURTAIN Bridge	MINI_IP_CURTAIN_vX.XXX.bin

Critical installer warning.

Do not install Modbus Bridge when the site needs normal SmartAPEX CAN, HVAC, templates or SmartAPEX TCP services.
Do not install Standard Mini IP when a Fibaro QuickApp expects a transparent Modbus TCP gateway on port 1502.
Do not install MiCURTAIN firmware for a Modbus device — MiCURTAIN is a proprietary curtain-motor protocol.
Use only the current approved MiCURTAIN field release; do not deploy test or unapproved builds.
Upload the encrypted package from the update-generator updates folder, not the raw STM32CubeIDE Release .bin.

Role 01

Standard SmartAPEX Mini IP V40.

The normal Mini IP gateway role for SmartAPEX CAN devices, built-in Modbus/HVAC configuration and standard TCP integration.

Project: SmartAPEX-MiniIP-V40 · Package: MINI_IP_vX.XXX.bin

Function area	Standard V40 capability
Ethernet gateway	Normal SmartAPEX TCP/IP services and web configuration.
CAN devices	Discover, configure, refresh and bind compatible SmartAPEX CAN devices.
Modbus RTU	Built-in bus, device and point configuration; register logic stays in Mini IP.
HVAC / templates	Built-in HVAC mapping, device templates and point configuration.
Maintenance	Network, diagnostics, reset and firmware update pages.

Do not use this role when

A third-party client expects a transparent Modbus TCP-to-RTU gateway.
A Fibaro Eastron QuickApp must send its own Modbus TCP requests directly to an RS485 meter.
The installation uses the proprietary MiCURTAIN motor protocol.

Important distinction. The Standard V40 Modbus section manages its own devices and points. It is not the same product role as the transparent Modbus Bridge and does not expose the same port-1502 workflow.

Role 02

SmartAPEX Mini IP Modbus Bridge.

A transparent Modbus TCP-to-RTU bridge for Fibaro/Yubii or another standard Modbus TCP client.

Package: MINI_IP_MODBUS_BRIDGE_vX.XXX.bin

Modbus TCP client

APX-MIP-P / port 1502

RS485 Modbus RTU slaves

Receives a Modbus TCP request and preserves its transaction ID.
Converts Unit ID and PDU to Modbus RTU on RS485.
Validates the RTU response and returns a Modbus TCP response.
Serializes RS485 requests so only one RTU transaction is active at a time.
Does not decode Eastron values — register interpretation remains in the external client or QuickApp.

Setting	Default
Network	DHCP enabled
Modbus TCP	Port 1502
RS485	9600, 8N1
RTU timeout	3000 ms
TCP clients	1 simultaneous

Fibaro / Yubii settings

Parameter	Example	Meaning
Gateway_IP	Mini IP bridge address	Target gateway IP.
Gateway_Port	1502	Transparent Modbus TCP port.
Modbus_Address	Meter slave ID	RS485 Unit ID selected by the client.
Read_Every	30 s or slower	Recommended polling interval.

Capacity planning. Recommended: 1 to 8 meters. Supported: up to 16 with suitable polling intervals. Advanced installations may reach 32 only with correct RS485 wiring, termination, biasing and slower polling.

Role 03

SmartAPEX Mini IP MiCURTAIN Bridge.

A dedicated RS485 role for supported proprietary curtain motors controlled through the SmartAPEX QuickApp.

Project: MiCURTAIN · Package: MINI_IP_CURTAIN_vX.XXX.bin

Setting	Default / range
Network	DHCP enabled
RS485	2400, 8N1
Motor ID	0–99 (0 = group address)
Channel	1–16

Fibaro QuickApp setting	Use
Gateway_IP	Device network target.
Motor_ID	Selects the motor.
Channel	Selects the motor channel (1–16).
Reverse	Reverses open/close direction — on only if needed.

Do not use this role when

The RS485 device is Modbus RTU.
The site needs normal SmartAPEX CAN or HVAC functions.
A generic Modbus TCP client must connect on port 1502.

Network discovery & role switching

Use the same protected update process for every role.

Use the same protected web update process for all roles, then verify the installed role after reboot.

Switching firmware roles

RecordSave the current IP and any settings required after conversion.

UpdateOpen /update, select the encrypted package and start the update.

RebootKeep power and Ethernet connected until the unit restarts.

VerifyOpen /version.cgi and confirm the new role and firmware version.

ReconfigureEnter role-specific settings and update controller parameters.

Network discovery

After factory reset, current firmware packages use DHCP by default.
Find the assigned IP with SmartAPEX Finder, the router/DHCP client list or supported discovery information.
Configure a static address on the Network page only after recording the current address.
If the saved static address is outside the installer subnet, reconnect correctly or follow the documented reset procedure.

Role	Version	Encrypted package
Standard Mini IP V40	vX.XXX	MINI_IP_vX.XXX.bin
Modbus Bridge	vX.XXX	MINI_IP_MODBUS_BRIDGE_vX.XXX.bin
MiCURTAIN Bridge	vX.XXX	MINI_IP_CURTAIN_vX.XXX.bin

Configuration does not guarantee migration. Standard CAN or Modbus templates are not a Modbus Bridge meter list, and MiCURTAIN motor settings are not Standard V40 records. Verify or re-enter role-specific settings after conversion. Use the encrypted packages from the update-generator updates folder — do not upload the raw STM32CubeIDE Release .bin through the web updater.
