Configuration Z-Wave

I seem to get the error messages during startup since the upgrade, any ideas?

Just thought you guys should know.

Cheers.

Did you read the release notes? There were major breaking changes in ZWave that required renaming all devices. It was laid out by @robbiet480 in depth along with a work flow to updating. I used his instructions in the post and while it took a bit of time it worked like a charm.

Yep - I followed all the notes and renamed everything.

Not sure what’s happening but sometimes I get these errors on startup and sometimes I dont.

I’ve just restarted again (testing another fix by changing some polltimes) but this time i’ve got:

Weird errors; I can’t say I’ve ever seen them before. Is there a chance you could have missed any references, like in a group or an automation/script?

no - i checked them all & all fine.

I’ve rebooted 2-3 times tonight and not seen them since. Very odd.

Oh well no worries. I just thought they looked serious and somebody here should know about it.

Thanks anyway @rpitera! btw - you seen my other issue?:

I have id3ntical issue and behaviour. Can it be that something calls the zwave device before it is Ready?

That’s a good thought. Not sure where to go with it though…

I just looked at it but I get a lot of cross talk in my Zwave devices too - none of which are Fibaros - and since everything was operating nominally I didn’t give it a lot of thought.

I don’t think it would be a bad idea to raise an error on github, even if you just get told it’s normal. At least you’d know for sure. Honestly, ZWave is still a bit of a black box to me. Things work, but I’m not always sure why… LOL

I have been getting this error myself now and still getting it on .32.3. All of my ZWave devices are working and reporting normally, but I get this error on every restart now.

Did you ever raise an issue on github?

Sorry not thought about opening an issue on github as i only saw it once maybe twice.

If i reboot now its fine.

I’m also getting this error. Could I ask how the response time is on your z-wave devices? I’m experiencing 5-30 second delays on mine, and judging by the logs, the delays seem to be coming from HA, rather than OZW.

I haven’t seen any delays myself. Haven’t been seeing this particular error since going to 33.3 either.
