A solid or blinking white LED ring on your ZEN06 Smart Plug is never a good sign. 

This could indicate that the electronics malfunctioned due to the connection of an improper load, or it could mean the plug is defective.  

It can't hurt to try performing factory reset on the device. This type of hard reset will erase the Smart Plug's memory, clearing all recorded activity and custom settings. To complete the process, simply plug the device into a grounded receptacle. Then press and hold the Z-Wave button for at least 20 seconds. If reset was successful the LED ring will flash solid yellow for 2 seconds.
