Zooz 800 Series Z-Wave Long Range S2 USB Stick ZST39 LR, Great for DIY Smart Home (Use with Home Assistant or HomeSeer Software)

This dongle is working great with Home Assistant via Zwave-JS-UI, both running in a Docker container. I have been very impressed with the stability of Z-Wave vs Zigbee (primarily due to its use of 800 MHz vs 2.4 GHz signaling), and am contemplating moving more of my home automation and monitoring items to Z-Wave because of the stability and range which I need for the various things I want to track in our home and outbuildings.

Works perfectly. Easy to set up in Home Assistant. Detected all of my (old!) devices

I'm using this for my home automation via Home-Assistant.I migrated from a SmartThings setup & am VERY pleased with the change.Installing was as simple as plugging it in & enabling, no special drivers or firmware updates were required.Using this device to unpair Zwave devices from SmartThings was a breeze, & everything paired quickly/easily with my new Home-Assistant server.Range is outstanding! I have this Zooz USB connected to my Home-Assistant server tucked in an out of the way closet at a far corner of my home. Even so, I've experienced zero issues or delays controlling devices at the opposite corner corners of my somewhat large home.It's also worth noting that I live in a densely populated neighborhood, with lots of tech savvy neighbors making the RF spectrum quite noisy... and still I have no connection/control issues.I am very pleased with both this device & with Home-Assistant. I'd recommend this change to any current SmartThings user!

Bought for my HA installation. Works like a charm.

Works like a charm with HomeAssistant running on Synology NAS... But, Don't buy Synology...

Use this after seeing what other HA users recommend. Plug-and-play, no issues. Understainding the versions and protocols can get confusing, and older stuff should be cheaper, but it does just work.

I bought this to replace a Razberry shield that I've been using for years, with regular frustration about range and disconnects. My previous setup was fragile and I was really nervous about moving the Z-wave devices. I reached out with a pre-sale question and got a quick answer from the support team; based on that and the info on their website I decided to give it a try. My experience has been fantastic - up and running very quickly, the software has a far superior dashboard to what I was using previously, and during two months of use it's been rock solid so far, with noticeably faster response time than the previous setup. Great value, I'm very glad to have made the switch!

This long-range Z-Wave adapter is a game-changer for my self-hosted home automation setup. It integrates perfectly with Z-Wave JS on my Linux system, with zero configuration issues. The range is impressive—I’ve noticed a huge improvement in connectivity with devices throughout the house, even in areas where the signal used to struggle. For anyone serious about reliable, robust home automation, this adapter is a must-have. Highly recommend!
