Can I just take the USB ones I have now and plug them into a spare Pi that I have lying around? If so, what would I have to run on the Pi in order to seamlessly allow HA to use that data?

Sure. For Z-Wave, install Z-Wave JS UI on the Pi and connect to HA via the Z-Wave integration. Not a Zigbee user, but I presume you'd need to use zigbee2mqtt with the MQTT integration for the same.

Ok, it made sense to but wanted to float it out there before I tried. When I do that, am I going to have to re-set up everything? Because that would double-mega suck.

#

Not for Z-Wave, but what are you using for Z-Wave now? Which add-on.

#

Z-Wave JS

You can follow this guide, but instead of using the ZUI add-on, you would install it on the Pi and import the backup the same way. The URL would then change to point to your Pi. https://community.home-assistant.io/t/switching-z-wave-js-addons-with-minimal-downtime-z-wave-js-official-to-z-wave-js-ui-community/409904

Oh, is JS the old and busted, and JS UI the new hotness?

drifting sleet Jan 31, 2025, 10:26 PM

#

No

#

Ok. Why move to JS UI instead of sticking with JS?

#

Unless you are planning to have a second installation of HAOS, then you can't use add-ons outside of it.

I think I missed a step:

"You can follow this guide, but instead of using the ZUI add-on, you would install it on the Pi "

What is "it" in this context?

drifting sleet Jan 31, 2025, 10:30 PM

#

Z-Wave JS UI

#

So that's something I can install standalone on the Pi?

drifting sleet Jan 31, 2025, 10:31 PM

#

Yes

#

Gotcha. I'm slow but I get there eventually...

#

Then in HA, I'd just go to the Z-Wave JS integration and point it at the Pi?

drifting sleet Jan 31, 2025, 10:32 PM

#

There's no Z-Wave JS integration, it's just Z-Wave. But yes, that's all covered in the guide.

#

You have to follow the steps exactly or it won't work. Unless you don't care about completely wiping all your HA devices.

#

Got it. I'll dig in a bit on my own. Just needed someone to tell me it was do-able and point me in the right direction so I can RTFM.

#

And no, I very much care. So thanks.

#

You could in theory install HAOS on the Pi, and use it only to manage the Z-Wave JS add-on, you'd need to expose the port (in add-on settings) and do the same re-configuration in HA. But for me that's overkill.

#

And just ignore the HA Core part of it
