Reset is a good move if your ZEN20 Power Strip is unresponsive to commands or shows no LED activity whatsoever. 

Click-click-click’n’hold the CH1 button for at least 10 seconds to reset your ZEN20 Power Strip to factory settings. All of the LED indicators should flash to confirm a successful reset. If you don't receive any LED confirmation, try the reset again, this time pressing the CH1 button more firmly.

Hard reset will erase all custom settings and recorded activity so that your device is restored to factory settings. 

After resetting the strip, try including it to your Z-Wave network again to see if that helped the issue. 

If reset doesn't help or if you have general questions about the process, let us know! Our team is always happy to help.
