Hi,
The 255 byte is no KNX standard dpt. However it's send over KNX IP to be able to send data to another controller. grp.update only blocks telegram to TP so when your ETS is connected over IP you will get invalid dpt telegram in the monitor, so your solution to block it in filter does do the trick. Keep in mind that your telegram will not reach other controllers now.
