Hi, I am running Nodered, Homeassistant, Zigbee2MQTT and KNX in my House (all updated to most recent). I have the following nodes installed and working fine:

- node-red-contrib-home-assistant-websocket
- node-red-contrib-knx-ultimate
- node-red-contrib-zigbee2mqtt

I want to be able to switch a zigbee lamp from a KNX wall switch. The lamp is powered, so this is only about getting the KNX message translated to Zigbee. The KNX group address for switching in my example is 1/1/64, the status GA is 1/4/64. The wall switch sends on or off depending on what's in the status GA.

When I use the switch to switch on, the following payload is generated: (sorry for the color scheme)

How do I get the message into the right format?
