Z-way is not great as an automation platform. It is outstanding as a zwave bridge. In terms of capability/stability it is #1 or #2 with HomeSeer ahead of hubitat/SmartThings and way ahead of openzwave. That’s why a combination with Home Assistant would be of great interest for some people.
as far i remember there was a mqtt bridge for z-way in their appstore.
The request I made has been submitted exactly for this reason:
Z-way -> mqtt plugin -> MQTT Broker -> HA
I should rely on a third party plugin that connect to an MQTT broker that will send messges to HA. Definitely more complicated than just using direct API.
I do have a MQTT container in my setup, but setting up and maintaining security there is one more thing to manage.
Event troubleshooting would be more difficult.
If MQTT is the path, I think more than half of the integration of HA could be dropped

thanks for your answer ha4dummy.
u are right… the best thing would be a good intigration… the question here… will it happen? and will it get maintained…
u are right to have additional tools like mqtt running brings more maintenance and maybe security issues… but keep in mind the mqtt will just run locally in ur network and is not connected to the outside world.
but trust me from my experience the mqtt “devices” got way more updates then the z-wave stuff… and if u wait for something specific u maybe wait forever…
and so far i had no issues with the discovered mqtt devices…
So, please vote now
Been requested before as I can see:
Now the question is whether it is worth waiting for openZwave to catch up with QT or if it is easier to develop a new integration.
Sorry, it must for sure be my inability. I have tried both setting up openzwave (zwave2mqtt) and zway (on ubuntu) the latter was feeling more intiutive… but with both I have not succeeded to stop with Vera. I currently run Vera Edge (@rafale77 knows me from there :-)) and the way that integration is done in home assistant is EXACTLY what I would like to see for z-way. If I were good in programming 
…
I have done the same. Z-way is definitely much more intuitive and goes much deeper into the support of zwave than zwave2mqtt. It is also a lot more reliable even if zwave2mqtt is not nearly as bad as vera. I know we discussed this but since you are able to setup Home Assistant and Zway, you should definitely be able to setup openluup and move your vera over and then migrate.
In case you’ve never seen this:
I then have Home Assistant and openLuup work in harmony. You could even use the vera integration from HA to connect to openLuup. The vera platform is taking a turn from bad to worse with ezlo, heading for another very different market and abandoning their user base. Your desire to move is understandable.
My strategy would be… since openluup is just another layer/viewer of the “logics and automation” on top of the vera ones I might as well use home assistant and node-red for that. I currently use Vera almost (few old automations left) only as a zwave bridge. All other stuff I migrated to hass as integration or custom component.
And since Vera is just a zwave bridge for me (with very poor and bad zwave device support) I want another zwave bridge (z-way) and gradually move 1 by 1 my zwave devices over to there. That way I can maintain my automations and logic via hass and node red and phase out vera and make use of a reliable and supported z-way product.
Your strategy makes perfect sense… Only if that bridging existed… I upvoted in support.

I’ve been searching this exact thing for months. Would really like to have a stable z-wave environment.
Then vote in the top!
z-way is going to be supported in Q3-Q4 acouding to z-way.me, its suppose to replayce open z-wave ( i talk to support that stated this) quote “The one we plan is to replace OpenZWave in HAss by Z-Way library and hence will work on the same box.” and are you reliseing this with z-wave 7 “Yes, this is planned for end of Q3 or Q4”
Wow, if confirmed, this would be a huge piece of news!
Do you perhaps have a source?
The source is zwave.me support, dont how clearer i can say it? I have been mailing with a guy called serguei since il was asking for a integration to use zwave.me on a raspberry and connect it to my nuc running HA
I see, He is the CTO of zwave.me. I’ve had discussions with him in the past. He is generally pretty reliable but it would be best if this would be confirmed by Home Assistant devs. Maybe zwave.me is writing the integration themselves and will implement it as a custom component?
I asked them as well:
Hello,
Could you please let me know if there are plans to integrate z-way in home assistant as integration?
I am a Vera user and have some zwave.me devices (older) and whish to step away from Vera as my zwave bridge to an alternative… z-way. But the heart of my current home automation is home assistant and that will not change.
Thus please let me know to wait or to invest in an alternative.
Thank you.

Why would that make you reluctant? It doesn’t seem to be any different from any other local startup supporting funds in other countries.
Something is happening…
Hello!
We are working on a project that will allow to use Z-Way library as the core of Z-Wave in Home Assistant. First releases will be around June/July I believe
Additionally there are ways to support Z-Way from HAss via HTTP requests. This is a community project and we have no deep knowledge about it.
