I just received a D’link DCH-Z510 Z-Wave siren and would like to trigger the various alarm sounds depending on the type of alarm (fire, burgler and so on).
I’m facing the same problem. According to my research, we currently don’t have any option to send this notification report from Home Assistant. According to this google group thread, the Z510 siren only reports a SWITCH_BINARY command to the Z-Wave controller, but not the NOTIFICATION_REPORT command.
It is technically possible to send the NOTIFICATION_REPORT command manually. The guys from Vesternet reverse-engineered the Z-Wave commands and wrote a guide on how to build the manual message. Unfortunately, OpenZWave (which HA relies on) does not implement any function to send these manual (raw) commands. There already is an issue for this on their Github and the solution doesn’t seem too complicated, however the issue has been open since April 2016.
This means that we will have to wait for the feature in OpenZWave first and then for the HA devs to update the OpenZWave library version. Our best option in my eyes is to show interest in the OpenZWave issue in order to push the feature. If you found any other solution, please let me know.
