I am running into an issue where the iBlind is marked as 'Dead' in Home Assistant Z-Wave control panel very shortly after pairing. This happens regardless of whether I pair at the final location or pair right next to Home Assistant\Z-Wave stick and then move the final location. I've been able to get it to recover once via randomly pushing buttons but most of the time it doesn't and I am forced to remove failed device and pair again.

While it's easy to assume this is a range issue, the final location for the blind is literally 3 feet away from a powered Z-Wave device (light switch) which works flawlessly.

Interesting things that I've found so far:

1) Z-Wave is marking device as dead because it doesn't respond to several commands in a row:

2020-01-11 01:05:25.340 Detail, Node108,   ZW_SEND_DATA Request with callback ID 0xc1 received (expected 0xc1)
2020-01-11 01:05:25.340 Info, Node108, WARNING: ZW_SEND_DATA failed. No ACK received - device may be asleep.
2020-01-11 01:05:25.340 Warning, Node108, WARNING: Device is not a sleeping node.
2020-01-11 01:05:25.340 Error, Node108, ERROR: node presumed dead

2) Z-Wave is reporting that the node (even while it's still functional after pairing) doesn't have any neighbors:

2020-01-11 00:55:14.001 Info, Node108,     Neighbors of this node are:
2020-01-11 00:55:14.001 Info, Node108,  (none reported)

I imagine this may explain the issue I am having as the device is only communicating with the controller directly not via other z-wave devices?

Any suggestions\ideas?

Thanks!

I have the same issue sometimes it months and sometime weeks. Would like to have a solution for this

@rvhu Same for me. each of my 4 iblinds motors are dead. and I can't revive them without repairing them to the controller.
