If you have a Z-Wave device that was previously paired to another smart hub and you have removed that hub or want to switch your Z-Wave device to another smart hub, you're going to run into some issues. When you try to reset that Z-Wave smart device to pair it to another smart hub, you'll notice that your hub won't be able to establish a connection to this device.
This is because Z-Wave devices don't remove all of it's settings when it is reset normally. Unlike Zigbee which allows you to reset a device and immediately pair it to another hub, Z-Wave has to be issued an exclude command before it can clear it's controller information.
Luckily, you don't have to use the same hub that the Z-Wave device was previously connected to in order to reset it. In the SmartThings Classic app there is a utility that allows you to put your SmartThings hub into exclusion mode to clear the Z-Wave device's controller information.
Follow these 9 simple steps to exclude your Z-Wave devices in SmartThings.
Download the SmartThings Classic app from the app store if you don't already have it installed on your phone or tablet. When the installation is complete, open up the app.
At the top left-hand corner of the screen, tap on the icon with 3 horizontal bars stacked on top of each other.
Tap on the button that says Hub is Online to view the SmartThings hub's settings.
Tap on Z-Wave Utilities located at the bottom of the menu.
Tap on General Device Exclusion.
Putting the SmartThings hub into Z-Wave exclusion mode will allow you to remove a Z-Wave device that has been previously paired to another hub's Z-Wave network. When you are ready to exclude your Z-Wave devices, tap on the Remove button.
Follow the instructions that came with your Z-Wave smart devices to successfully exclude them from another Z-Wave network and be able to pair them to a new one. Every Z-Wave device has a different method of resetting itself, so you will have to find this information on your own.
A few ways some of these devices are reset is by holding down a button on the device for a set amount of time or by pressing a button a certain amount of times. Each device is different and if you can't find the instructions for your device, do a google search to find out how to exclude or reset your device.
If you properly reset your Z-Wave device you'll see a message pop up that says, Successfully removed a device.
Now that your Z-Wave controller information has been reset, you will be able to connect this device to another Z-Wave network. If you have more Z-Wave devices to exclude, repeat the same process for each device by following the manufacturer's instructions on how to reset them.
If you are finished removing Z-Wave devices, you can take your SmartThings hub out of exclusion mode by clicking on the Cancel button.
