Zwave "not functional"

since yesterday Zwave module nonoperational.
restarting, disabling, enabling , zwave doesn’t respond.
hard to believe, but looks like hardware failure. Any ideas?

Contact ST support at


What device/make? My neo coolcam 2ch switch went down a few days ago ( just 1 of 2). Works manually but nothing in the app

He was referring to the z-wave module in the ST hub :slight_smile:

HUB back on for few seconds/minutes after I disable and enable and than fails again
