I think you have to read the complete thread. Everything is explained why this is not working yet.

Doorbell is added now, but only a lot of parameters which are not corresponding with the manual. Standard volume level is way too high (distortion), but no option too decrease the volume level. Hope that the new openzwave version is coming to Domoticz.

Version: 4.10717

When including Domoticz sees the device as Aeotec Unknown.

Strange thing that on another site they mention there is support for Domoticz... https://www.robbshop.nl/sirene-z-wave-p ... b-aeonlabs

I have bought the siren 6 and it's possible to include the siren, but there is no configuration file and I cannot set the siren on status " ON". I get a error message: "Error sending switch command, check device/hardware !". So I hope the siren will be supported soon, because this is the only siren ...
