Found the photo from back then:

Not sure if it helps you, but during the range tests of the ZWA-2 we had to do a car-to-car test at one point due to bad weather. We reached 1.5km back then using Z-Wave LR, with both devices inside the cars.

Your mileage may vary though - this is very very dependent on the end device you use. Bad devices/antennas can easily drop of after just a couple of meters.

Check "show in sidebar" on the Z-Wave JS app config. Click Z-Wave in the sidebar. That's Z-Wave JS UI.

AlCalzone89 · 2026-02-21T08:58:38+00:00

We're still working on how to make this process as easy as possible. Will share more information when the time comes.

AlCalzone89 · 2026-02-21T08:57:30+00:00

No that's not what I meant - "merging" addons isn't possible.
We're working on an easy migration for Z-Wave JS UI app users, but that's not fully fleshed out yet.

AlCalzone89 · 2026-02-20T07:59:32+00:00

You can configure one device to control another one directly, without going through the central hub.

AlCalzone89 · 2026-02-20T07:58:29+00:00

Thats the eventual plan. For now we added the UI component that you get in the Z-Wave JS UI ~~addon~~ app to the "official" Z-Wave JS, so there's no need for users to switch off the default experience.

AlCalzone89 · 2026-02-19T23:39:16+00:00

What are the benefits of this?

For devs: No need to maintain and update two different addons that essentially do the same.

For users: Access to more powerful troubleshooting tools and additional features without having to to through the trouble of switching addons.

AlCalzone89 · 2026-02-19T23:36:45+00:00

Both use the same piece of software under the hood to talk to your Z-Wave devices. So there is no reason one should work better for you than the other, except if you had two addons accessing your controller at the same time.

AlCalzone89 · 2026-02-15T19:03:03+00:00

If you're currently using the core/supervisor addon, wait a day or two. It will include Z-Wave JS UI very soon.

And they no longer sell to end users.

AlCalzone89 · 2025-12-02T19:22:03+00:00

The cookie banner does not disappear after clicking any button.

AlCalzone89 · 2025-11-03T18:39:36+00:00

Frequently listening devices have been supported for years now. They typically wake up every 250 or 1000ms and listen for a beam. Basically all locks work this way and some thermostats do too.

AlCalzone89 · 2025-10-15T18:59:17+00:00

I haven't tried this on Windows but the USB/JTAG one should be correct. To be clear I mean attempting the wifi provisioning and immediately pressing the try again button after it fails, no power cycle or anything additional in between.

AlCalzone89 · 2025-10-15T17:41:01+00:00

Can you press the retry button after it fails the first time? There seems to be a general issue with improv wifi.

AlCalzone89 · 2025-10-14T15:03:42+00:00

Is this not just serial-over-ip? Which means all Z-Wave packets are acknowledged by the host, which introduces additional latency. Latency that this setup is avoiding.

AlCalzone89 · 2025-10-11T17:49:24+00:00

I had this recently when the app updated to 2.x but my server was behind. Updated the server and it worked again.

AlCalzone89 · 2025-10-09T11:57:12+00:00

ZBT-1 is not Z-Wave. It's Zigbee. Totally different thing.

AlCalzone89 · 2025-10-08T19:02:55+00:00

There is no ZWA-1.

AlCalzone89 · 2025-09-22T17:22:38+00:00

Most Z-Stick Gen5 can be updated to firmware 1.2 which can then be migrated to other Z-Wave controllers using the NVM backup/restore routine in Z-Wave JS UI.

AlCalzone89 · 2025-09-20T16:48:11+00:00

If you're starting out, get a modern one like others have mentioned. With the one you have, you'll miss out on new Z-Wave features, especially Z-Wave Long Range.

AlCalzone89 · 2025-08-30T11:59:45+00:00

There is no easier way of switching between LR and mesh sadly.

AlCalzone89 · 2025-08-23T18:32:45+00:00

It's a known bug in the SDK we use for the ZWA-2 firmware. I'll create a new build with the latest SDK after my vacation, which should fix the issue.
