ALL Zwave devices dropped, module dead, hub replacement on the way, I'm gonna be sick

Did you see this thread… you are not alone:

Z-Wave Died: eeprom write fail

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.
