Hi.

I've just being trying out Z-cloud and quite like it, however it doesn't seem to work reliably in my setup. Response can be quite slow, and sometimes it seems to get "stuck" or out of sync. For instance it has happened that turning a light off does nothing, then turning it back on actually turns it off! It seems like the commands get stuck in a queue and get executed at the wrong time.

I've also checked the log, and it's full or ERROR statements similar to the ones below:

My setup is as follows:

Linux PC (Mint 11)
Aeon Labs Z-stick S2 (EU version)
4 ACT Plugin dimmers (ZDP200)
2 Duwi wall dimmers

Some more information:

There never seems to be a problem when sending commands to only one node at a time, but sometimes when several are involved in a scene. I've enabled the "queue inspector" and I can see that sometimes the "Ack" and "Resp" columns get a + but not "Cbk" (Callback?)

Yes, if the delays due to Internet connection are big, some async might happen. But still the order of packets is never changed: you simply see first packet delivered too late (when you already pressed another button).Note that this might also happen if the device is at the border of direct reachibility. Update routes. Also try to add one more repeater in between. Usually this helps.You can turn off sending multiple commands at a time. Do do this create a scene with one single script:ZWaveAPI.awaitingCallbackJobs = 1Activate this script and check. If this will help, we will make a config parameter, so that you would be able to change this setting yourself without scene tricks.For now note that you have to activate this scene every time you connect to the cloud (you can put it in schedule every minute to be sure it was executed).
