I’ve been talking to the folks at Zensys and Aeon (who makes the dongle) about this. Unfortunately this is one of the REALLY frustrating time wasting bugs because it’s random, intermittent, and we can’t reproduce it in our office. I’ve never seen one of our dongles lockup like this, and it seems to only affect 10% or so of the users.
So there is something about certain homes that is causing the dongle to lock up. Either (a) a defective dongle, (b) some combination of Z-Wave devices that’s causing the Z-Wave module to go haywire, (c) environmental factors like ambient temperature or electrical interference, or (d) ???
In the case of the Z-Wave dongle problems we suffered until the new dongle recall, the problem was (b). There was a bug in the Z-Wave 5.02 serial api that caused some sort of stack overflow particularly when there was a mixture of new 44 kbps Z-Wave modules with the old 9 kbps modules (ie Intermatic).
Since we can’t reproduce this, and neither Zensys nor Aeon has heard of this, what we need is the help of a user that has seen his dongle lockup frequently and regularly. If we can have a volunteer, I’d like someone to check ‘verbose logging’ and ‘lock log levels’ in Advanced Logs. Then everytime there’s a dongle lockup, submit a trouble ticket, go to Advanced, Tech Support, click ‘enable it’ to turn on the back door, and send me an email to aaron [at] micasaverde and put DONGLE LOCKUP in the subject line so it gets my attention, and has the back door code. Don’t reset the dongle until I’ve had a chance to log in and see what was the last thing the dongle did so I can find a pattern, and keep a log of the lockups, the frequency, time of day, etc.
Once we confirm you have a dongle that locks up regularly, I’d like to send you (a) another dongle with the identical firmware, (b) another Aeon dongle that does not have the Aeon battery and inclusion button active, and (c) a stock Zen-sys dev board running the same version of the Z-Wave module. We can use the clone dongle function to make all 3 new dongles exact mirrors of the existing dongle. And then we should see which of those 3 new dongles still locks up. That will isolate if it’s just a defective unit, a defect in the Aeon design or Aeon battery/inclusion stuff, or a general problem with the Z-Wave firmware itself.
I know this is kind of a nuisance for a user, but it would be much appreciated if we could get a volunteer. This benefits not just Mi Casa, but everyone in the Z-Wave community. The bugs in the 5.02 Z-Wave modules which caused all that instability in the past, and which were fixed in July, were isolated and identified because of our testing like this. So when we were able to demonstrate it to the Zensys engineers so they could fix it, it benefited everybody in the Z-Wave community because that Z-Wave unreliability was plaguing every Z-Wave product on the market that supported security. I have a suspicion that this dongle lockup issue is also a universal one effecting every Z-Wave controller, and probably is not unique to the Aeon dongles.
