Thanks for your reply!
How do you poll the device? by creating a separate rule machine to manually poll the data every x seconds? The current device configurations:
Hm, didn't know there is such z-wave+ product; would Aeotec Z-Wave Smart Switch 6 is classified as one of them?
Also, the UDP error is caused by LIFX light strip (LIFX Multizone custom driver); haven't got time to debug it as yet...
Update:
I ran rule machine every 10 seconds to poll the switch, unfortunately, it's getting worse, the switch is not ON at all when I make a movement
