All my ZWave devices are suddenly unavailable, but still mostly work

sebk-666 · July 30, 2021, 10:19am

Hi,
I’m running 2021.7.4 as a docker container on a QNAP NAS.
An Aeotec Gen5 Z-Stick is plugged into the device and mapped into the container.
HA still uses the “classic” zwave: integration configured via configuration.yaml.
This has been working for years now.

Yesterday, I had to install a firmware update on the NAS and reboot it - not sure if the FW update is of any relevance here.
When HA came back up, I noticed that all my zwave.* devices were (and still are) reported as Unavailable - except for the Z-Stick, which is in Ready state.

Most of the devices create some associated sensor.DEVICE oder binary_sensor.DEVICE entities which seem to be working ok - for example, I have an Aeotec Multisensor 6 in my kitchen named “aeotec_ms6_kitchen” and all the associated sensors like e.g. sensor.aeotec_ms6_kitchen_relative_humidity report sensible values.
On the other hand, I also have a couple of Everspring Window sensors and their binary_sensor.everspring_sm103_door_window_sensor_sensor_N entities are also shown as Unavailable.

The log file does not reveal anything to me; there’s a lot of “complaining” about nodes that are not ready on HA startup, which I think is normal.

Does anyone have an idea what’s happening here?

I’ve had host updates kill Zwave
Always keep backup of stick

Power cycle a few devices and see if they connect

You may need reconnect devices

This never happened to me before and I’ve been running HA with ZWave for years now.
The devices are connected - except for the Everspring Window sensors, everything seems to be working, e.g. automations based on the Aeotec motion sensors get triggered; I can set my thermostats without any issues - it’s just that they (i.e. the zwave.* entities) all show up as unavailable although they clearly are working just fine.
I also see all the nodes’ chatter in OZW_log.txt.

Possibly a cache corruption, it’s not an uncommon occurrence with the legacy z-wave integration. To confirm, you can stop HA and check your zwcfg*.xml file. If it looks like there’s a lot of missing information about the nodes (names, mfg, all the command class info), it means the cache was corrupted. You would then either need to restore from a backup, or delete it and re-interview all of the nodes to re-create it.

Thanks! That seems to have been the issue - my zwcfg_*.xml file was basically empty - I restored it from backup and now everything looks good again, HA-wise.
