Hello,
I’ve started noticing some performance issues with my z-wave network these last few days. In particular, one GE 14291 switch stopped sending instant updates to HA when turned on/off (though it would respond to commands from HA). So I removed the switch and reset it - that was a process - and it seems to be working fine again.
However, I’ve now noticed some big lags in my system which indicates heavy traffic. I checked the OZW logs and I noticed a GE 14294 dimmer being polled every few minutes. Here is a log excerpt from 4:30 am:

I only have polling setup for one of my switches on 40+ device network and it is an EATON dimmer that I had to use and the polling_intensity is set to 15.
Does anyone have any suggestions? it seems odd that this device is suddenly starting to flood the network and I vaguely recall having the same issue with another dimmer a few months ago - I think a reset and re-add fixed it.
Would adding a custom entry in the zwave_device_config.yaml with polling_intensity: 0 help resolve this issue? I’m just trying to figure out first what causes this random issue and second, the quickest fix.
Thanks for the help,
Will
