After referrals I ended up here with device problems

[rap27]

I apologize in advance if my question does not belong here, but I am looking for a solution

domotic sets topic (they referred me to zwave js)
https://www.domoticz.com/forum/viewtopic.php?p=307028#p307028

github zwavejs ui (they indicate that they may suspect that it could be a black hole between MQTT and Domoticz and zwave js)
zwave-js/zwave-js-ui#3298

I work with Domoticz everything works in docker-compose and works well
domoticz. Version 2023.2 build 15457
MQTT. Version 2.0.18
szwen js ui. zwave-js-ui: 8.26.0.08e6a7e
zwave-js: 11.14.3
homebridge.

now it wants the device to not wake up Aeotec Siren 6 in Domticz in HA, they can get around it and get it working through adjustments.

my and other Domoticz users cannot get this siren to work in the domoticz environment in combination with zwavejs ui and mosquitto MQTT
in the outdated environment with openzwave it worked.

now I get 8 devices with volume and 8 devices with status
this is 2 devices per sound

the device volume is a dimmer function and I can of course slide it to, for example, 40% but then nothing happens, and in the log you can see that this has been set
Status: User: x (IP: x.x.x.x.) initiated a switch command (1419/siren aeotec 6_volume_dimmer_1/Set Level)
and that's it .

Now in a different way, I go to Zwavejs Ui and select a sound and you will see the status turn on in Domoticz. so that works.

Now it has been suggested on the topic in ZwaveJs that it could be an MQTT issue. Can someone help me, since I am a user and not a programmer, I hope to get this device working. but I have no idea where to look and from forum to forum I now ended up here through referrals.
