Today I am having issues repairing my zwave network after making some changes and I noticed a lot of eeprom write fails in the logs. The message has been updated to provide a memory address in the eeprom and I noticed that it changes. Given eeproms have a limited number of times you can write to them before they start failing, I wonder whether this message is essentially saying the eeprom chip is starting to fail. If we find the specifications of the eeprom chip inside the hub it will tell us how many writes it can go through before it may start failingā¦ of course we do not know how many times the hub writes to it but it seems it does so relatively frequently. If the eepromās write cycles are in the millions then I donāt believe this would be the case but if it is in the thousands then we may be onto somethingā¦
I notice Err 112: ZM eeprom write fail after hub reboots. Also having occasional slow processing, delays, and a few zigbee devices going offline each weak.
Reliability (response of lights on with motion) has been inconsistent for a few weeks for me. Still on Hub fw v17.12.
Hi aruffell,
Regarding the āZM eeprom write failā messages, we just recently updated the logging to include the number of bytes and the offset in the EEPROM to allow us determine where and how often this issue is occurring. We are updating only when a new device is included, as a result we are updating only one byte in the EEPROM with the offset incremented each time. Therefore the likelihood of hitting the 10,000 EEPROM limit is very unlikely.
We are currently investigating the cause and workarounds to this EEPROM write failures, hopefully we should have a workaround very soon.

@Kianoosh_Karami - Thank you for the insight. I am guessing the eeprom is on the Sigma Design Zwave module used on the hub as I could not find an individual eeprom chip on the PCB. That might also be what the āZMā abbreviation stands for.
I looked at my Events List for the past 6 days and found quite a few of these error messages - 66 or so Err 112:

I have been having some issues with a few devices so the errors may have increased due to me trying to figure out the issues but at this rate my eeprom would potentially start showing issues after 2.5 years. Unless this is what is causing me grief right now, I hope to upgrade to a future v3 hub before then.
Regarding the āGot CRC-16 encapsulated commandā, We are seeing these with some Z-wave devices. We are fully compliant with the CRC-specification provided by the Sigma Designs. We have noticed these with a few specific devices, I am not really sure why the messages we are receiving from these devices are incorrectly encapsulated. Perhaps, this is the reason they added the CRC-16 encapsulation to ensure the messages are good when passed between the application layers.
I am currently looking into the EEPROM write failures. Hopefully I should know more soon.
Thanks
+1 as I get these failures all the time.
I just wanted to give an update on this issue. I have found ways to reproduce this issue, and I believe there is a limitation on the Z-Wave chipset that can skip EEPROM writes when the network is busy. In order to write to the EEPROM, they need to halt their CPU which can shut down the z-wave network momentarily and given their primary objective is to handle the Z-Wave network, the EEPROM writes could be dropped. As a result, we are going to add retries and a sophisticated system to get away from using their EEPROM for future. This will be in future firmware releases. Thanks for the patience.
@Kianoosh_Karami - You mentioned that the write happens when a new device is included but judging by my number of failures it seems to be happening under other circumstances as well. What happens to the system when those values do not get saved to the eeprom? Also, what data is being written to the eeprom?
We are seeing a huge drop in EEPROM write failure issue in 19.13 Firmware Beta Release.
Hopefully once we release the 19.x to everyone, you might initially see the issue (with no bad consequence) a few times (due to nature of the bug), but hopefully cleared for the long term.
The reason I say no consequence is because we have added retries and timeouts that has shown to cover the residue from the found bug in 18.x release and before.
Let me know what you find and I can certainly dig in more. Anything Z-Wave related really.
Thanks again
For those users that have upgraded to 19.x, let me know if you experience this issue anymore.
19.19 is turning out to be a Z-wave train wreck. It appears that the frequent, numerous Z-wave reboots are back. Probably 2 dozen events in the past 12 hours so far and counting.
Hereās one example from today. This device, āCeiling Fan in Purple Roomā is literally 3 feet away from the hub!

Do you know what changed in 19.19 that has impaired Z-Wave so badly?
Steve, we have not changed anything Z-Wave related since 19.17.
The root of the problem remains to be the Z-Wave chipset, which when 20.x gets released should allow us to update the firmware on the chip and hopefully the issue is solved.
