Aeotec Gen-7 Zwave stick, new firmware 7.21.3, still jammed controller and dead devices

Configuration Z-Wave
21

Z-Wave JS UI does this all automatically.

You need to re-configure Z-Wave JS UI with the correct USB path so it recognizes the 500-series controller. If you’re using the by-id path, those will not be the same. Then you need to restore the NVM backup.

Note NVM backup and restore to/from a Gen 5 requires the Gen 5 to be at firmware version 1.2.

This worked, had to change the usb path. Somehow still lost all zwave devices in the network, even after restoring the back-up. There are not that many devices, like 5. Guess easiest fix is just to re add them?

24

Did you do a Backup and Restore under the NVM Management function? This is not the same as the regular Backup.

I feel dumb now. Let me try and fix this.

26

@freshcoast I got an error while trying to restore the NVM backup to the 5 series stick. It said the file is too large?

27

Is your Gen 5 on firmware v1.2?

28

Yes it is. Just tried it again and now it’s restoring so that’s good. No clue why I got the size error the first try.

All nodes are back. I would be nowhere without you guys. Thanks! Going to explore the gen 5 stick now and see if my nodes will be more stable.

Mine were instantly better then after a bit of fine tuning on routes (which I could finally do without stalling the network…) Anyway, two days later I e-wasted my 700 stick. (nobody needed to inherit that nightmare)

The 500 stick I moved to is still my daily driver for a ~100 node network. Hope it works well for you too.

So far my nodes are still not looking great. What’s a good place to read up or any tips on how to fix this? I’m just clueless why nodes are “unknown” and unresponsive. That combined with my limited knowledge, makes this challenging.

You have a new coordinator - it didn’t miraculously fix everything. :slight_smile: Now time to get healthy.

Who knows the why without looking at your zwave log. Generally start out with reinterviewing them. If they continue to fail interview (unknown like that) repair the route to the device then… reinterview it again, if it continues to fail watch the interview in the debug log while its happening and see if you can see where its failing -fix that route. Repeat as necessary. For the dead one - ping it - see if it comes back, repair its route, then reinterview it.

Thanks that’s a starting point!

Im a total noob on zwave but i still cant understaind why such a big issue is taking this long to solve, does anybody have more insight?

35

The problem is with the manufacturer of the basic chipset that is used for the 700 series based ZWave transmitters (SiliconLabs).

No idea what their problem is, but for three years they still haven’t fixed the problem. No clue whether it’s the hardware design of the chipset itself or a firmware issue, but again, in the latest release notes they still mention this as an issue.

36

Anyone tried the 7.21.5 version already?
Also SL has released a new SDK 2 days ago: Releases ¡ SiliconLabs/gecko_sdk ¡ GitHub

Lets hope for the best :slight_smile:

37

Do you use a 500 stick that supports S2?

38

Yup no problems at all. Won’t deploy a 700.dont need LR. So 500 for now. If I move it will be for a new feature but for now it’s perfectly fine.

39

Thanks, that is good to know.

I am on a 800 (Zooz - ZST39 with firmware 1.50 - SDK 7.22.1) now, but my network just went completely down 30 minutes ago. It’s just horrible. I had to pull the USB out and back in to get it up and running. The controller was completely jammed.

I used to be on a 500 that was stable for years. I wanted to upgrade because of the S2 security and I have a lot of temperature sensors that support that. Not that it’s really necessary but it works well. The 500 stick I had did not support it. Now I am stuck with an unstable network. :frowning: This morning I came downstairs seeing that the lights have been on all night.

Already ordered a new 500 + stick with S2 support. Hopefully the NVM backup will work without a problem and I will have a stable network again. :slight_smile:

I think there must be something on your network jamming it. I have 2 homes with over 100 ZWAVE devices on ZST 39 with zero issues. What did your logs say as that will help. I used to have a dodgy thermostat that was an absolute hog.
