My z-wave network had been stable and operating well for almost 2 years with about a dozen nodes. I’m running Hassio on a Raspberry Pi 3 with the Z-Wave.me UZB stick.
Around the time when I upgraded HA from 0.81 to 0.83 I started getting issues where my zwave devices stop responding after several hours (8-48 hrs from the logs I’ve kept). In looking at the OZW_Log, it seems that all of the nodes, including node001 (the controller) stop responding.
‘Heal Network’ doesn’t restore the network
Restarting Homeassistant doesn’t restore the network
Hassio host reboot DOES restore the network
Power cycling the Pi DOES restore the network
I have since updated to HA 0.85, then 0.86.1 and now 0.86.2, and still have the same issue.
At this point, mt best guess is that my UZB stick has gotten flaky.
Also, I’m not sure, but my power supply might be making a louder hum than it did before so that might be a cause. I hooked it up to my oscilloscope and the output looked pretty stable, but trying to catch a glitch that happens once every 8-48 hrs is sort of challenging.
I know there were some changes to OZW that were done in 0.82, so I can’t rule out a software issue. Is there an easy way to do a downgrade in Hassio? I tried the method I found here:

using:
curl -d ‘{“version”: “0.81.6”}’ http://hassio/homeassistant/update
to get the last known good version, and hassio responded with
