That is like linking to the Z-Wave JS Config DB Browser, or the Catalog of Certified Z-Wave Products listings, both of which are cool but not always super useful for mains-powered devices since they do not say contain AC specifcations and specifications nor say the device is still manufactured/sold or if so are made for which countries. So those can be a start to find devices but at this time you then still need to do a lot of research own your own after that before buying a specific product.
Hopefully the planned Device Database from the Open Home Foundation that was brought up in the roadmao will contain such information and thus be more useful:
And literally none of those are what I was talking about in my post. Good luck finding a decora light switch in Zigbee - there are a few out there - somewhere, but they’re rare, as mentioned.
To be fair, when I search Amazon (US) for Jasco Zigbee switch, I get exactly two Zigbee switches from GE and then a few pages full of Z-Wave switches and Add-on switches from GE.
One dimmer and one switch are definitely better than zero, so thanks for the heads up.
I just picked up a Zooz 800 radio for Z-Wave which is working well with all my Z-Wave gear and should work with EU gear when I move the setup. Light switches however may end up moving to Aqara on Thread at that time.
They have in recent months kept hinting that it will be announced soon, so suspect that a release date will probably be officially announced on the blog very soon, but if it will be available for purchase at the date of the annoucement is a different question:
Quote: ”Watch this space for a not-so-secret Home Assistant Z-Wave hardware announcement coming your way”
Paulus has very strongly hinted verbaly several times duing the last few Home Assistent release party videos that their Z-Wave Controller adapter will be available ”soon” so one could guess that it will be in stock and available for sale when it is announced (as the Home Assistant Green and SkyConnect was).
There is also a new rumour now about additional new hardware because in the latest video Paulus also hinted that there will not only be a Z-Wave Controller USB radio dongle but there will maybe be another hardware announced as well then, so my guess there is that they will also announcing a optional matching ESPHome serial-to-USB network adapter that can allow users to convert the USB dongle into a network connected adapter which would enable you to place it anywhere on your local LAN (or maybe not anywhere if it is PoE powered and only uses Ethernet instead of WiFi. At least I think those are realistic guesses based on the related ”USB Host” and ”USB UART” features that was recently added to ESPHome → ESPHome 2025.6.0 - 18th June 2025 — ESPHome
PS: ZBT-1 and ZWA-2 are still terrible product names IMHO, as I think they should be called something like ”Home Assistant Zigbee or Thread USB radio adapter” and ”Home Assistant Z-Wave 800 USB radio adapter” or alternativly just call them by some color and version like their hub appiances (e.g. Home Assistant Purple USB radio dongle).
To be fair my entire smart home is nothing but z-wave zooz for all devices except 2 hydrometers with water leak detection (aeotec) and 3 basic hydrometers (bluetooth govee).
For zooz I have 8 dimmers, 1 double relay, 1 single relay, 1 universal relay (two relays with two sensor inputs) for garage, and 1 universal relay (3 relays with 3 sensor inputs) for controlling my car via key fob.
I’d wait on this one since it’s still uncertified. There’s a giant warning on the site:
Important Notice:
Z-Wave support in this device is non-certified and is included strictly for evaluation and testing purposes . These are not certified , not for commercial deployment , and are clearly labeled as non-Z-Wave certified samples .
Personally, I’d recommend getting a ZWA2 and installing it with a POE ESP32-S3 as described here. I swapped from my previous TubesZB setup with the Razberry 7 Pro to the ZWA2 with this setup and it’s been an amazing upgrade.
These guys know what they are doing with Hardware design. They will go for cert soon and there will be OTA FW upgrades as needed. Personally I’m not so sold on the design of the ZWA-2.
Paulus and Frenck hinted again during the Home Assistant 2025.9 Release Party (September 2025 release video) that is probably a USB-over-IP ”bridge” in the works as well(?):
And by ”bridge” I assure USB-over-IP software or even USB-to-Network and hopefully wired USB-to-Ethernet (hoping for optional PoE) as in this discussions:
Paulus also hinted about upcoming Zigbee Coordinator USB adapter which is why my guess is that there could or should be new hardware in the form of a universal USB-to-Ethernet adapter which you can plug in any USB radio dongle.
With how good the Seeed Studio XIAO W5500 Ethernet Adapter is (the one used in those discussions), I cannot imagine any additional features Nabu Cass would add that would make me want to upgrade (unless it “docks” physically into the ZWA2 base).
I also can’t imagine they would have it available in the next 3-6 months based on how long the ZWA2 took from its first hints (top of this post). It might be worth waiting for Nabu’s solution for some people, but if you need a solution now, this is probably the best option available today.
