Domoticz

Firstly I am 99.9% sure this is not a Domoticz issue however i am at a loss as to where to look next, I will do my best to describe what I have and the problem in the hope someone can say "have youy tried ?"

Hardware / Software
Pi 3b+ with latest 64bit Bookworm fully up to date installed on SSD.
Mosquitto
Zigbee2MQTT
Domoticz

All of the above installed with out issues, z2m can see mosquitto (obviously or it would not start) and I can add devices to z2m and control them from the front end, interogating the mqtt server with mqtt explorer I can the devices in question.
Domoticz has MQTT auto discovery installed and "Accept new Hardware Devices" is on but nothing shows up.
I also have an ESP32 with ESpresense installed, again I can the BLE devices it detects in mqtt explorer and they appear in domoticz.
So all systems appear to be running, there are no errors in the log for Domoticz, I do not understand why zigbee devices do not appear. I have done multiple builds in the past for myself and other people with no problems, the only difference here being latest version of mosquitto and z2m 2.0 but if Domoticz can see mqtt devices from ESpresense why can't it see z2m devices.

Any ideas ?

Did you enable Home Assistant Integration in Zigbee2MQTT?
This generates the discovery topics that Domoticz auto discovery is using. Also make sure the topic name in Z2M is the same as in Domoticz AD hardware.

BINGO !!!!
That was it, all good now. Did I miss this because in z2m 1.xx it was enabled by default and it isn't in 2.xx or am I just going senile
