The panel is not responding to any link quality tests on our end. Do you have any Z-wave devices powered off in that area?
First try a reboot of the panel (Settings > Advanced Settings > Reboot Panel) Do the currently malfunctioning devices communicate after the panel boots up?
If that doesn’t have an effect, try powering off that Z-wave garage opener, then reboot the panel again.
Activating them sends a status to ADC which will resolve the offline malfunction. If any of the devices still show malfunction or do not update their status after activating them locally, that may point to that device as a culprit.
You can also use the system manager to send a sync z-wave device list command, which also updates status.
I’ve sent a link quality test to the panel and everything reports good signal currently. Let us know if you notice this behavior again, and if so, is it in the same area.
