Here is one example where my lock has sent zigbee messages according to the zigbee logs, but both Hubitat and Rooms Manager say it is inactive:

Also the reason I asked about whether you used the events page data, is that I also have seen cases where Hubitat reported the "Last Activity At" for a device at a later time than any of the events on the events page. But again I also see messages in the ZIgbee logs for even later times than either. Below are the logs of such an example:
