For Z-wave issues a full shut down and unplug for 30 seconds is needed to restart the z-wave radio.
Use my custom drivers for the two Zooz devices and enable Debug logging indefinitely (for now). This way you will see every event from the device in the logs, even if it is duplicated and otherwise not seen in the event history. [DRIVER] Zooz Sensors Advanced (ZSE11, ZSE18, ZSE40, ZSE41, ZSE42, ZSE43, ZSE44)
Usually that is the case and only would make things worse, turn that off.

Since you said NO events come in, I would assume that means no, they are not working, since for the ZSE44 you should be getting regular events from the device as temps change.
