I need to send a KNX individual address property write frame from a Lua script to a DALI gateway at physical address 2.2.4. Specifically I need to write to object index 6, property 0xDA to trigger a post-installation scan, and then poll the same property by reading it back to check when the scan is complete. I also need to write to the same property with different data to flash individual DALI ballasts for identification purposes.
The grp.write API only supports group addresses so I am trying to use a UDP socket to connect to the LM's own KNXnet/IP tunnelling server on port 3671 and send raw cEMI frames. However the CONNECT_RESPONSE always returns status 0x08 regardless of whether any other clients are connected.
Is there a supported way to send individual address property write/read frames from Lua on the LM itself?
