I sometimes struggle with my zwave network:
- Z-Wave ZME_UZB1 Me
- Fibaro Plug
- Dual Switch FGS-222
After some days (not reprodicible) I get loads of timeouts in the openhab.log:
2016-03-10 12:27:21 [WARN ] [WaveController$ZWaveSendThread] - Receive queue TIMEOUT:
2016-03-10 12:27:26 [WARN ] [WaveController$ZWaveSendThread] - Receive queue TIMEOUT:
2016-03-10 12:27:31 [WARN ] [WaveController$ZWaveSendThread] - Receive queue TIMEOUT:
2016-03-10 12:27:36 [WARN ] [WaveController$ZWaveSendThread] - Receive queue TIMEOUT:
2016-03-10 12:27:41 [WARN ] [WaveController$ZWaveSendThread] - Receive queue TIMEOUT:
2016-03-10 12:27:46 [WARN ] [WaveController$ZWaveSendThread] - Receive queue TIMEOUT:
and NO zwave device can be switched any more.
For troubleshooting I setup an timeout item for the USB stick:
Number Z_Timeouts “ZwaveTime-outs [%s]” { zwave=“1:command=info,item=time_out” }
Sometimes it shows 20 timeouts (after a few days) but the zwave devices are working properly.
When I see the loads of warnings mentioned above I don’t see a significantly higher number of timeouts in the item, but the network is not operational any more.
I would like to reboot (that fixes the problem) or heal on many entries of that kind above.
Is there ana other (meaningful) item / property I could monitor instead of the “timeouts”?
