WTH is going on with Z-Wave - my devices keep disappearing

Whether I am using the old Z-Wave integration where I occasionally lost all my devices and had to rebuild my network to the new Beta openzwave integration where so far I have had to rebuild my network multiple times so far.

I am starting to wonder when I will get a working, stable, Z-Wave integration inside homeassistant?

This sound like an issue on your side. Both the Z-Wave integration and OZW work without any issues for me and lots of other people.

How does “losing all devices” manifest itself and does it happen at a specific interval or after some event or similar or just random?

Let’s talk about the new integration - it’s what I am trying to use right now. I have open issues with ozwdaemon where it seems to stop publishing node data to MQTT topic. I can see the node and attributes but no state data etc… I can resolve the issue temporarily by deleting the ozwdaemon ozwcache file. But the problem has come back 3 times now. No clear reason why as yet.

Hmm ok, that sounds strange. Do you have a lots of z-wave devices? If not, I’d try removing all nodes and readding them.

Not many around 15 at the last count. Around 5 mains powered smart plugs and the rest are motion sensor PIRs a flood sensors and a mains powered Z-Wave repeater. To be fair they are all currently visible in ozwadmin. MQTT explorer shows all 15 along with ="{NodeID…}" strings. Hass is showing 13! My front door PIR’s binary sensor is unavailable and the living room PIR binary sensor is not reporting as a motion sensor anymore since the last ozwcache rebuild.

I am sure Z-Wave should not be this hard!

I migrated all my door sensors from Z-Wave to Zigbee using ZHA with a cone stick and I have to say they have been rock solid ever since. Given time and inclination I want to move all of my Zwave networ over to Zigbee on the basis that it just works.

Yes I could and probably will continue to rebuild my Z-Wave network again and again but probably not until we get a next release of the Z-Wave code.

I don’t want to seem overly critical but the vast majority of my posts to these forums have been around my frustrations with the stability of Z-Wave with HA.

I’m planning the same, only have 5 Aeotec Multisensors on Z-Wave and more than 50 ZigBee devices now. However, I really like the Aeotec Multisensors and as long as they continue to work, I use them.

What Zigbee PIRs did you settle on?

I have just the one Aeotech Multi-Sensor and around 4 or 5 NeoCoolcam PIRs and a Aeotech flood sensor. I have a couple of inner smart plugs for Zigbee from Amazon which seem to work well but they don’t do power monitoring like the Aeotech ones.

I have one from hue which works fine. The thing I like about the Aeotec is that I can set the time until it sets back to no lotion after motion has been detected. Lots of motion sensor have a fixed interval 2 mins and more…

and again unavailable devices:

and in MQTT:

Time to delete ozwcache…

There was a bug introduced in one of the 0.113.x versions that was causing all sorts of issues for many of us. For me, and a couple others, it was z-wave devices showing up as undefined. The fix was included in 0.114.3. Not sure if it will help your situation but it resolved all the problems I was having.
