You can confirm the command is sent via the debug driver logs. https://www.home-assistant.io/integrations/zwave_js/#how-to-access-the-z-wave-logs
If it’s being sent but not sticking, then it’s a device problem.
I just set it by the api, on this light. And it works. So thanks! There is also a patch on github to allow this: LZW31-SN -allow higher minimum dim level up to 98 for FW 1.57+ by kreene1987 · Pull Request #5181 · zwave-js/node-zwave-js · GitHub
If you want to use that config file, then you will need to switch to Z-Wave JS UI. https://zwave-js.github.io/zwave-js-ui/#/device-support/custom-device-files
Oh. Is the official zwave js addon, config files in a different location?
The official add-on does not support the ability to use custom configuration files. You can do it if you access the data volume directly, but that is unsupported.
Ok. Do you know where the official configuration files are on GitHub so I can do a pull request? Nobody should have to go through the pain I have with flashing different versions and testing the minimum dimmer value. Lol
You’ve already linked the pull request.
I think there was a misunderstanding. You could use custom config files in the official add-on, but you need to manually access the docker volume that contains the cache directory and copy in the files. Accessing add-on files is not officially supported, so this is not a good solution for most users. If you know how to, go for it.
On the other-hand, Z-Wave JS UI has a directory browser that lets you upload files, which you can use to upload custom configuration files. See the doc link I posted previously. Anyone can do this without any hacks.
Ok. Thanks. Good to know about that.
Hi,
I try to run “Z-Wave JS UI” beside my “Z-Wave JS” integration. I only want to use the panel(s)
The configuration is like
It tells me, that it is connected by I don’t see any devices
and if I click on
or
I get an error.
Anything I can do?
Thank you!
That won’t work. You can’t run both beside with a single coordinator. You have to choose one. 
But the documentation says that it should work
https://zwave-js.github.io/zwave-js-ui/#/homeassistant/homeassistant-official
and here
I try now to switch to “Z-Wave JS UI”
@BebeMischa: you pos here
says
Add the Z-Wave JS integration again (even though it is still installed), and uncheck the “Use the Z-Wave JS Supervisor add-on”. Enter the correct address for the community add-on in the URL field in the next step
How do I find out the correct address for the community add-on ?
Thank you!
EDIT:
Ok, did find out what I have to do.
In the add-on configuration I have enable the port of let say it better I have to enter a port. I have used 3000 and re-added the z-wave-integration with the checkbox unchecked and the default value displayed
No, you don’t need to enable any ports in the add-on configuration. By doing that, your z-wave server is exposed outside of the host to everything on your network. It’s unauthenticated and insecure. If that’s something you care about, you should remove the port mapping and just configure the URL (ws://a0d7b954-zwavejs2mqtt:3000), which is given in multiple docs:

I think the confusing part of this for me was understanding the documentation here Z-Wave - Home Assistant
For example it maybe could be re-organized to be , a separate page for exact steps one would do to enable the Zwave JS UI addon with the default home assistant that most people run on raspberry pie?
Come on guys. its been months and every update breaks things even more and theres no solution anywhere that I could find, I have sent many support tickets and never got a return from them. maybe someone here can help me fix this. I already pretty much switched all my devices from Zwave to other things. but I still have my garage door and a my garage light on a zwave system. this is my config:
Aeotec Z-Stick USB Gen 5
Garage Door - GoControl GD00Z-8-GC
Light Switch - GE z-wave Jamcco
Garage door has not work in months, Light switch keeps working and stoping on evey update the have. this is my log as of today
Your hardware/os can’t talk to the stick. Something else on the system is using it or it’s a broken stick.

“Cannot lock port” usually means you are running both Z-Wave add-ons (official Z-Wave and community Z-Wave JS UI) at the same time, which is not allowed. Is that the case? If so, there are plenty of post in regards to this.
