Exclusion should be your go-to move anytime you have trouble adding any Z-Wave device.  

Give exclusion a try if you've attempted to include the plug, but you're seeing configuration issues or are generally unable to add the device to SmartThings. Exclusion is a Z-Wave reset that can help with these types of issues. Devices don't need to be included properly to be able to be excluded.

Here's how to exclude the unit on the SmartThings app: 

1. Open your SmartThings app and locate your SmartThings hub under Devices. Tap the hub to see the device details. 

2. Tap the three dots in the upper right hand corner and tap Settings

3. Tap Z-Wave Utilities 
4. Tap Z-Wave Exclusion
5. While the app is searching for a device, click the Z-Wave button on the device 3 times very quickly
6. The app will indicate when the device is successfully removed. Tap Done

Once exclusion is completed, try including the Double Plug again. If you're still unable to include the plug after exclusion, here are some alternative things to try:

• Try the exclusion process again! Sometimes commands from the first run aren't registered correctly, so it can't hurt to try again. 
• Try bringing the device closer to your hub and adding it from there. If the Double Plug adds without any issue, the first location may have been out of range. 
• Try the exclusion process again, only this time instead of pressing the Z-Wave button 3 times, try pressing the button 5-6 times firmly and as quickly as possible. This can help make sure the commands go through.
• And if you find that your Double Plug is connected but it's not responded to remote commands, check out these tips for troubleshooting connectivity. 

But if you're still seeing issues with the exclusion/inclusion process no matter what you try, please let us know! We're always happy to help.
