There are a number of Z-Wave sirens on the market including from Dome, Go-Control, Everspring and Aeotec. All allow turning on/off a loud siren over Z-Wave and some also allow triggering various chimes or uploaded audio files. As far as I can tell there is no support in HA for a device of this type at all - it would be a great addition to help complete the security system picture. I ordered a Dome Z-Wave Siren and am willing to help test.
Have you tried to pair it yet?
I donāt have it yetā¦ will post back when it arrives.
Detailed docs are here. OpenZWave didnāt have it in the library so I manually updated XML files, the siren was recognized by OZW. The config parameters all work. I created a pull request on OZW for the XML files. The siren shows as a switch in HA, so the main siren is usable, but the chime feature is really not available.
I suppose I could change several config parameters each time I want to have it chime; through config it can trigger the āsecondary notificationā when the binary switch is flipped. Then I can also set which sound it makes through config parameters. Then Iād need to flip the switch on and off, then change the config back so the siren will sound when the security system is tripped. Iām not going to try that though, because Iām confident it will take way too long to sound the chime after, say, a door opens.
The secondary chime is normally triggered through the Z-Wave Indicator command class. OZW knows about this command class but I donāt think HA does anything with it. As I understand it, Indicator is a one-time message - i.e., send the message, the chime goes off a number of times set through config parameters on the device, there is no need to send another message to turn it off.
So I suppose the siren works fine as a binary switch, though itās not the best conceptual fit, but there is a possible totally new feature here to support Indicator command class devices.

@netopiax - Sorry to bring back an old thread. Did you ever have luck using the chimes with the Dome Siren?
Glad to see the thread revivedā¦ My Dome Siren is siren only, no chimes. I havenāt tried writing a script that will set the config parameters and then turn the switch on/off to trigger the chime, because Iām confident that even if it works, its response will be too slow to be useful. My opinion: there needs to be a new feature in HA to support the notification class of Z-Wave devices on the notify HA platform.
I like that feature request! Lets make a new one so others can vote on it since we are able to add sirens to our system.
OK, Iāll do it. It is actually the Z-Wave āIndicatorā class that needs support.

Any update on this? I really want a siren/chime device I can integrate into my network.
The proper feature request is here - no movement from developers. Iād invest time but this is probably beyond my skill set, at least without a lot of fumbling around first.
I could be interested in taking a look if/when I get this device. Have no idea what Iām doing but it could be an interesting learning experience 
Looking to do the same thing. I have a Dome Siren attached to my setup; if anyone can give me some direction on coding the commands I can work on this.
I did some initial work and found that OZW has the indicator class already we just need to bring this into HA.
Iām a bit new to this so please be gentle.

I also see the indicator class stuffs in my xml. Someone else was trying to say that the device needs to be added to OZW but Iām not sure thatās the case.
I messaged Dome inquiring about them adding the device to the OZW database a few days back and am still awaiting a response.
The Dome Siren device is in OZW already - I know because I added it myself 
Based on the discussion on this post I created a new feature request quite some time ago, that has more votes than this one, that is specifically about the Indicator class being added to HA. Again, I donāt think any OZW changes need to be made to do this.

Ahhh, good to know. I wasnāt sure if it was in OZW as it didnāt populate everything(new to Z-wave.) Does the OZW database automagically get merged into HASS?
I commented on the other post already.
Yes, HA picks up updates to the OZW project including the device database on a somewhat regular basis. It may not always have the very latest, but the Dome Siren is coming through as expected.
Good deal. So itās just the indicator support part of it/python that needs work then. Thanks again!
Bumpā¦ Any progress on this? I was looking at the Dome or other sirens as well to add to my Home Assistant or if anyone has suggestions. I like the idea of chimes too.
Please vote on the feature request here. The latest info is that Open Z-Wave doesnāt yet support the Indicator class and until that happens thereās nothing Home Assistant devs can do.
This indicator class?
