Recently i’ve been suffering from poor and/or unreliable z-wave performance in my system.
What are the symptoms?
Receiving information is fine: Status updates (e.g. motion, temperature, door status etc) are immediate and never troublesome
Sending commands is troublesome: Controlling Z-wave devices (e.g. turning on lights, controlling blinds) is either incredibly slow or it takes multiple tries before the command is executed.
When do these symptoms occur?
The complete unresponsiveness to commands occurs in the first approx. 30 minutes after either a full Openhab restart or a Z-wave binding restart.
After approx. 30 minutes the z-wave system seems to stabilize and becomes responsive again. but even then, when sending commands to groups containing multiple z-wave nodes, some devices (e.g. lights) are not responding to the commands given. When resending the commands the non responding devices do respond.
Openhab version : 2.5.0 build 1677 (openhabian distro)
Z-wave stick is connected to a RPI3 which in turn is using Ser2Net/Socat to connect to the Openhab VM
Log file containing over 6 hours of z-wave debug:
I’ve never experienced similar issues with Openhab and Z-wave but since a few weeks these issues started to appear and have been bothering me ever since.
@chris, as discussed let’s continue this in this topic. Thanks in advance for your help.
p.s i’ve used your log viewer and noticed a lot of “rejected by controller” messages for various nodes… perhaps something to look at?
Sure. Post a log file after you fix the above, and I’ll check for any other problems. I stopped looking after I saw the issues with 21, 61, and 67, as they definitely can cause commands to be delayed. But there might be some other things going on.
Sometimes the device config can be out of sync with what HABmin shows. Once you’ve fixed 21, 61, and 67, updating the meter config parameters from HABmin might restore the frequency to what you want.
