Selection Guide
Select by System Role, Not by the Word “Gateway”
Start with the systems that must communicate, then compare the verified protocols, interfaces, channel capacity, device quantity and commissioning method.
Tuya Multi-Mode Gateway

Choose this role when:
- Tuya wireless devices form part of the project.
- RJ45 network access is required.
- Zigbee 3.0 and Bluetooth Mesh devices must be managed.
Selection Boundary
PLC, KNX and RS485 connectivity uses the corresponding dedicated modules and should not be presented as standard built-in connectivity.
DDW1.1 & DDW2.1
KNX to DALI-2 Lighting Integration
Use the KNX DALI-2 gateway family when KNX commands must control DALI lighting devices through one or two independent DALI channels.
Choose this role when:
- KNX TP and DALI-2 lighting must communicate.
- One or two DALI channels are required.
- Up to 64 DALI devices per channel are required.

Gateway FAQ
Frequently Asked Questions About Gateway Selection
Review common questions about KNX DALI-2 gateways, Tuya wireless integration, TCP/IP and RS485 interfaces, device capacity and technical documentation.
What is the difference between DDW1.1 and DDW2.1?
DDW1.1 is a single-channel KNX DALI-2 gateway supporting up to 64 DALI devices.
DDW2.1 provides two DALI-2 channels, supporting up to 64 devices per channel and up to 128 devices in total. Both models support KNX TP, LAN commissioning and an integrated DALI power supply.
What interfaces does the X5 gateway provide?
X5 provides RJ45 network access, Zigbee 3.0 and Bluetooth Mesh connectivity.
KNX, PLC and RS485 connections are available through optional dedicated modules.
Does an RS485 interface automatically mean Modbus support?
No. RS485 identifies the physical communication interface and does not by itself confirm Modbus or another application protocol.
The required RS485 protocol must be checked against the formal documentation for the selected gateway.
Which gateway connects KNX with Tuya wireless devices?
The KNX Wired & Wireless Integration Gateway connects KNX TP with Tuya Wi-Fi, Zigbee and Bluetooth devices.
It supports up to 200 KNX channels, more than 400 wireless devices and up to 1000 control devices in the app environment.
Which gateway provides TCP/IP and multiple RS485 interfaces?
The KNX Multi-System Integration Gateway provides KNX TP, TCP/IP and five RS485 interfaces.
It is designed for KNX projects that require network integration and multiple RS485 connections within one system architecture.
Do these gateways support Matter, HomeKit, BACnet or Modbus?
No. Matter, HomeKit, BACnet and Modbus are not standard capabilities of the gateway models included on this page.
TCP/IP, RJ45 and RS485 describe communication interfaces and do not add these protocols.
How should I choose the correct gateway for a project?
Start by identifying the systems that must communicate, then confirm the required protocol or interface, DALI channel count, device quantity, wired or wireless architecture, power supply and commissioning method.
The gateway should be selected from these project requirements rather than from the product name alone.
What technical documents can be requested?
Available document requests may include product datasheets, installation manuals, dimension drawings, wiring diagrams and the applicable ETS, DCA or configuration files.
The exact document type depends on the selected gateway and its commissioning requirements.
