Ok, I’ll document what I discovered over the last couple days, and where I’m headed. I have a ton of old Lowe’s Iris stuff, which happens to be Zwave. After leaving it in my drawer for a year in utter disgust that Lowe’s abandoned the brand, I decided to try to get it to work on a PI.
Most of the minor things (light switches, thermostat) paired and worked without much issue.
I did discover that, since they were previously paired, I had to remove the Aeotec USB stick from the Pi, hold the button down until orange, and then put the automation tool into pairing mode to have it ‘forget’ the old Iris network. Once that was done, then I could pair by either pressing the Aeotec Zwave once for blue, pairing and then plugging in and rebooting the Pi, or pairing it via the UI.
However, it seems that some Zwave devices (looking at you, door locks) require the network key. However, the only way to pair with the network key is to have it in the Pi with webthings running, and the 16bit network key (which cannot be elementary school, and is case sensitive - lower alpha chars only) set up and running. Once I did that, I was able to get more information from the door lock (battery level) but I was still getting the jammed error. The log reported a timeout, but I suspect it was due to the fact that the device wasn’t a fan of the key for some reason - possibly due to it being a branded Iris device, and only wanting the specific Iris key? That’s a guess.
While researching the issue, I discovered the blog post saying that Mozilla is essentially shutting down the roadmap for webthings. Bummer.
Given all that, I’m going to postpone my experiments with webthings and check out Home Assistant for a while. Hope this helps someone. Good luck!
