My ~85 node Z-Wave setup mostly contains mains or USB powered devices. It has been working relatively well under Hubitat but I wanted more power so moved the Aeon Z-Stick Gen5 to an OpenHAB install 2 days ago. The move went fairly well, with all devices immediately showing up as Things and their manufacturer and device info being fetched over the following hours. I could control the devices and it all seemed fine.
On the first night I left it running and by morning most Things had gone to an offline mode. I tried sending commands but they didn’t respond. Over the following few hours they progressively came back online. I assumed they’d just been marked offline as they hadn’t been heard from for so long, so to avoid it happening again I set all Z-Wave devices to a “polling period” of 30 minutes.
On the second night (last night) I left it running again. When I went to bed I could control lights via Alexa and all was fine. There are no other rules or add-ons.
When I woke up today I noticed all devices were again offline. However this time they did not progressively come back online. I could not control any. I tried to restart the OpenHAB systemd process and debug level logging showed a flood of Z-Wave traffic from several devices. I attempted to change 2 x Aeon MultiSensor 6 to “selective reporting” (which had been overlooked from the Hubitat era) which seemed to cause most traffic. However none of the attempts to send that configuration change were accepted. I did a soft reset on the serial Thing but then OpenHAB didn’t talk to the Z-Stick at all. I assumed I needed to do a network heal but couldn’t find a manual option to kick it off, so I set the next heal time to 2 pm (the next upcoming hour) and cold restarted the server (and attached Z-Stick).
Nearly 6 hours have now elapsed since restart. A small amount of traffic is received, but control is either impossible or significantly delayed (minutes to turn a light on or off, if it ever does). All Things have a status of “Online Node initialising: PING”.
I have uploaded the debug-level log to https://ufile.io/16mh2097. A look at the log via https://www.cd-jackson.com/index.php/openhab/zwave-log-viewer does not show anything obvious like a device causing a flood.
Any suggestions what to try next?
