I added the Leviton Smart Plug to my ISY.  Everything works perfectly except when I manually activate the smart plug, its status is not reflected in the ISY without querying the smart plug.  The event log shows it is sending communications to the ISY when I manually activate the switch, but no change in ISY status.

@dougos2 Could you add some additional system details to try to help?

• What's your ISY994 Firmware? 
• What is your UI for Admin Console (Help -> About)
• What series Z-Wave do you have? (Use this post to help determine your series controller)

Do you have any other Z-Wave devices that report status correctly? I'm not familiar with the smart plug, but it's possible it is a newer 500 or 700 series device that isn't correctly sending information to the ISY994 z-wave module you have.  Perhaps others with more z-wave experience can chime in, but additional information on your setup could be helpful.

With you using the ISY, I believe that you must be on the latest firmware and have to query your devices since leviton uses hail vs sending status automatically like other modern zwave devices do.

Looks like might be a "known" issue with this brand/manufacturer. Here are a couple of old posts to review:
