KNX Ultimate 8
Node-RED + KNX
Connect Node-RED to your KNX installation. Version 8 includes six KNX nodes and one shared gateway configuration.
Nodes included
KNX Device
Send commands, read a group address and receive values from the KNX bus.
KNX Utility
Eleven functions in one node: scenes, timers, alarms, logging and other bus utilities.
KNX Viewer
View group-address values and the last 24 hours of telegram history.
KNX IoT Bridge
Connect KNX to MQTT, REST and Modbus flows.
KNX Multi Routing
Route telegrams between KNX gateways or provide a KNX/IP server.
KNX Router Filter
Filter or change telegrams before forwarding them to another gateway.
KNX Gateway
Set up the KNX connection, import ETS group addresses and configure KNX Secure. Shared by the nodes that use the bus.
The gateway is a shared configuration, not an additional node to drag onto the flow.
Optional integrations
Install these separate packages when you need them. HUE Ultimate and Matter Ultimate work with normal Node-RED messages. You can also use them with KNX Ultimate: select the existing KNX gateway to enable native KNX integration.
HUE Ultimate
One Controller for Hue lights, scenes, switches and sensors.
