I’m going to preface this by saying I have no logs to back this up because I wasn’t willing to use my house to test the issue I was seeing. However, I will relate my overall system performance:
After updating from 4.3.1 → 4.3.2, I noticed a significant degradation in Z-Wave performance. Rules that sent messages to multiple devices, such as turning out all the lights on the 2nd floor, usually would turn out everything within a few seconds. After the update, it would take minutes or longer before the first light turned off.
I have a Schlange Z-Wave lock on my front door. The battery had been reporting at 71% when it gave a sudden low-battery warning and stopped functioning. The batteries were so drained that it was immediately dead. I’ve never had that happen before. After swapping out the batteries, I suddenly had them die again just 48 hours later. A battery tester confirmed the batteries were dead.
The door lock, with the performance of the z-wave mesh, is what made me think that my controller was suddenly being overly chatty with my devices. I decided to roll back to 4.3.1 and suddenly the z-wave performance is back to normal. The front door lock seems to be the only battery device that was negatively impacted by this…none of my other battery powered devices are dead.
Not sure what anyone can do with this information without more details but I didn’t know if maybe anyone else was seeing strange behavior.
From a quick review, there have been no changes to the zwave binding (except changing the label (4.3.0 -->4.3.1 -->4.3.2) since OH4.3.0, so there is nothing to suspect without logs.

Honestly, while they are slightly different I’m not sure if either of these indicate I should adjust anything on the controller itself. It does seem to have a lot of ItemStateChangedEvents and I don’t know if there’s a way to turn that down.
I don’t usually look at these serial communication items (or have them linked), but on general ZW principals the missing FramesAcknowledged is a concern. It means that the controller on the serial port is not acknowledging messages sent from the binding on the server (at least in a time period shown). Nothing good can happen. In the future you could try a restart of the ZW binding, OH or lastly the server (in that order) to see if any of that helps clear up/reset the connection
Interestingly, the missing FramesAcknowledged was happening on 4.3.2 and returned after 4.3.1. In your opinion, would I be better off removing those items though?
As it stands now, I’m not going to upgrade to 4.3.2 for now because I don’t have time to troubleshoot this issue and I don’t want to get locked out of my house (that almost happened because of the dead battery )
