Have had 0 issues with it. Setup was a breeze. The radio reaches super far and the connection has been very stable. Would recommend.

Need to add Zwave to my home automation, this was easily setup within Home Assistant.

The radio is long range, did not even have to buy an extender or such. I plugged this and it recognized my zwave devices just fine.

Just bought this for my Home Assistant. Works perfectly. Only have one device connected but have many devices on order. I guess I I could just use zigbee but a lot of zwave devices are what I need for some situations. They have plugs and switches where I can't find a zigbee variant.

The value for the money was insane! Considering prebuilt hubs can run around $200 this usb stick is everything you need for zwave connectivity. I use it on my raspberry pi 4b 8gb with HomeAssistant and life couldn’t get much better. Everything is turned into a cross platform hub. If you like Google hub, Apple HomeKit, or the A-word you can set up your zwave devices to work with any of these. The durability of the USB stick seems well built. Connects to a standard USB type A port.

This was easy to set up and across our 1800 sq ft single story home, it connects to every Z-Wave device I have. I run it with Home Assistant on a Pi.

I purchased this Z-wave stick to add Z-wave connectivity to Home Assistant Green. This has worked flawlessly with my Z-wave devices for over 5 months now. So far there has been next to no lag on the devices. With several Z-wave sticks to choose from, I am very satisfied with my choice of this product.

Could not be any easier to integrate with HomeAssistant. Plug it in, recognized immediately, and took at firmware update via HA without any complaints. Immediately had moved all devices over from Smartthings in one night to HA using this stick.

I'm a Home Assistant noob but this little thing was so easy to get going. Plugged it into my raspberry pi 4 and added 3 devices right away. Pretty thrilled to have my alarm.com zwave thermostat and smart plug local now instead of using telus' network.

Działa z raspberry pi4 i home assistant. Bezproblemowe podłączenie do sprzętu. Na razie obsługuje dwa czujniki. Na razie żadnych problemów, żeby tak było zawsze 😀

I bought this to upgrade and replace an Aeotec Gen500+ USB stick in a HA Yellow. Migrating a 66 node network in HA JSUI directly, or via nvmedit convert.Immediately updated to v1.4 before restoring a backup. World of difference! The network came back up as it should, and lightning fast. My mesh has now recalculated and has less hops/more direct node connections than before. I'm now running 100% on the Zooz USB stick.I had a disaster with unpingable/dead devices with the GPIO and total success with the USB stick, changing nothing else. I don't have a small z-wave network, but be warned on the performance. I'll be buying another ZST39 as backup and getting rid of the Aeotecs now.The GPIO 'may' be better if you only plan on using it with LR devices, yet untested by me. Use simplicity studio ideally or update with no nodes added, or you risk bricking the device - happened to me with the GPIO module.Check this before you do anything else, start with at least v1.4 before adding nodes as there are many issues in previous versions which this stick likely ships with.Looks like v1.5 of firmware will be released soon, and Silicon Labs claim all transmit lockups are fixed in that versions release notes. I see them rarely now on v1.4 and it's not bad like it was, so doesn't damage damage the mesh/automations reliability

Bought two of these, 1 in HA OS, another one in Pi with ZWave JS UI, both works perfectly with HA, I love home automation now
