Six months back my Gen 2 Z-Stick had several episodes of the ‘all devices disabled’ problem, so I purchased a spare stick just to be on the safe side. I made a backup but continued using the old one which then started behaving itself…
About 3 weeks ago however, out of the blue it happened again. It seemed to be provoked on almost any device changes, even doing a single optimise network would kick it off. I copied the script from
viewtopic.php?f=58&t=19916&start=30#p163225 into a trigger which helped with re-enabling devices and notifying me, which is great, but if you can’t rely on the devices working then it’s a non-starter.
So when the system seemed relatively stable I backed up the Z-Stick and copied it to the new one waiting on standby. Guess what. Exactly the same problem. So I had just copied corrupt data from one Z-Stick to another. That pretty much rules out a hardware issue.
I had a ‘clean’ Z-Stick backup but it was out of date by now and how can you be sure there isn’t some corruption lurking in there?
Only one thing for it really, factory default the Z-Stick and re-include everything from scratch. Just 44 ZWave devices, 74 if you include the secondary ones. So I did that, excluding then including each device in small batches then re-syncing with the old indigo definitions, took over half a day and an evening to get them back and enabled. At least all the triggers, schedules & actions were still intact. Most devices needed parameters setting though, as if from new. That’s when you’re glad you’ve kept all the manuals
Anyway, It’s now 5 days and counting - no problems. I might copy the data back to the old Z-Stick and replace that at some point , I have a feeling it’ll probably work fine. (Glad I didn’t rush to buy a third Z-Stick!).
The question is, how is the data being corrupted in the first place?
I’ll post any developments…
