Connect ZWA-2 anywhere: Use Z-Wave over Wi-Fi or PoE

Blog

Hi. My use case is that I have a Pi with HA in my home and garage is just far enough away that zwave canā€™t make the hope to the garage. If I could have one zwave instance in my home, and another in the garage connected over my LAN, then that would be a perfect solution. Do you know another way? Thanks in advance.

Even to far away for the newest Z-Wave LR (Z-Wave Long Range, a.k.a. ZWLR) devices based on Z-Wave 800 Series hardware chip? See example ā†’ Z-Wave Long Range Devices - The Smartest House

When commission and choose to connect a such device via Z-Wave Long Range to the ZWA-2 adapter as controller it will not use mesh but instead connect directly using their LR technology which can be up to a 1-mile away in optimal conditions.

Again, another option is ti setup a second Z-Wave JS Server in the other location using for example a Raspberry Pi with its own dedicated ZWA-2 adapter as Z-Wave controller.

Sorry to hijack this thread, but Iā€™m having issues with a Waveshare ESP32-S3-POE board and a Sonoff Z-wave 800 stick. When configured direct to my HA host via USB, it seems to work just fine. Moving the transceiver to a Z-wave PoE bridge works for the most part, but I cannot include, exclude, or interview any devices. Tried using the zwave_proxy component in esphome and via esphomeā€™s api. Also tried tube0013ā€™s solution of using a stream_server direct to a tcp socket. Iā€™m completely perplexed why these basic functions arenā€™t working, yet I can see existing devices on the network and all the events coming and going from them. Thanks in advance if anyone can see anything obviously wrongā€“Iā€™ve been staring at this too longā€¦

Thank you for the info! Sorry for delay. I actually bought a LR stick and LR device, very excitedly, and was shocked to find that itā€™s range did not seem to be much more than normal zwave. That was about 6 months ago. If it worked well for you then maybe I will test it again.

If that does not work then I think the second JS server is the only option. I have never done that. Can both be controlled via the same HA instance or how does that work?

Thanks again!

You are now getting really off-topic so you start a new thread to ask for support to not hijack these comments, hence do not reply more about that here if have further questions. Anyway, in summery you first install a separate stand-alone Z-Wave JS Server with its own Z-Wave Controller on a different computer and then you just install another instans of the Z-Wave integration which you connect to that remote host instead of the local host ā†’ Z-Wave - Home Assistant

Update: I dug out my old Nortek HUSBZB-1 and tried that. No issues via zwave_proxy, so itā€™s something with the Sonoff adapter and/or how Iā€™m commuictaing with it. Also validated that there werenā€™t any funny usb power drops from the waveshare. Iā€™ll exit this thread for now, as my issue is clearly unique to the Sonoff. Iā€™ve reached out to them for suggestions and will post an edit for posterity if I get anywhere.
