Home Assistant and 2nd gen dimmer with S2 security --> discarding commands and status in HA wrong

Switches General Discussion
,
#1

hi there, I’m looking for some help since I’ve noted that the status in HA is not getting updated correctly when I’m using the physical switch. I don’t know if that’s an issue with the z-wave JS driver implementation of something that’s actually wrong with the dimmer firmware.

Below is a snippet from the logs and it clearly is unhappy about something with security. I know I can get rid of the issue by dropping back to S0, but that just feels wrong.

If you can rule this out being a problem in the FW, I’ll happily take this to the zwaveJS folks. The switches are on the latest release FW (1.57 & 1.45).

Thanks for your help/insights,
Patrick

Replying to myself, “solved” the problem by replacing the old Nortek z-wave/zigbee controller with a new Zooz ZST39 800 for z-wave and all is well. So not a switch problem, nor a zwave js problem - oh well…
