The SmartThings Hub is a Z-Wave-certified central static controller. It can be included in any Z-Wave network and operate with Z-Wave certified devices from other manufacturers. To add a Z-Wave device to the Hub's network or copy network information to another controller, check out our guide on setting up new devices. To control an included device, find the device in the My Home section under Things, and tap on its name to see the device detail view.
All non-battery-operated Z-Wave devices within the network will act as Z-Wave repeaters—regardless of vendor—to increase reliability of the network.
The SmartThings Hub is a security-enabled Z-Wave product. When a security-enabled Z-Wave device is added to the Hub's network, its secure communication will be 128-bit AES encrypted.
Command classes supported by the SmartThings Hubs
The following Z-Wave command classes are supported by the SmartThings Hub:
|Command Class||Version||Required Security Class|
|Z-Wave Plus Info||2||None|
|CRC 16 Encapsulation||1||None|
|Association Group Info||1||Highest Granted|
|Device Reset Locally||1||Highest Granted|
|Manufacturer Specific||1||Highest Granted|
|Power Level||1||Highest Granted|
The SmartThings Hub has support for the Association Command Class—it has one association group, the "Lifeline" group, which supports sending associated devices reset notifications when the Hub is factory reset. A maximum of 231 devices can be added to this group.
The SmartThings Hub does not map the Basic Command Class to any functionality. It ignores Basic Get requests, though in some cases of legacy support for older Z-Wave sensors it may interpret Basic Set commands as sensor activation events.
The SmartThings Hub controls devices with unknown device types using the basic command class, and optionally controls other devices with the basic command class.
Using the SmartThings Hub as a Secondary Controller
Because the Hub is a certified Z-Wave device, you can add it to another Z-Wave network. Note that you can only add a Hub to a different Z-Wave network if no Z-Wave devices have been added. Otherwise, you should remove all Z-Wave devices from the Hub first by putting them through a device exclusion. When the SmartThings Hub is used as a secondary controller on a Z-Wave network, it may not receive notifications from some battery-operated devices. SmartThings Technical Support does not provide assistance to consumers using the Hub with other Z-Wave central controllers.
Here are the steps to put the Hub into learn mode to receive network information from another Z-Wave controller:
- Prepare the other Z-Wave controller to copy its network information to the Hub. This may be called include, add, transfer, shift, copy, or replicate mode
- In the SmartThings Classic app, tap the menu (Android) / More (iOS)
- Tap the Hub
- Tap Z-Wave Utilities
- Tap Add Hub to an existing Z-Wave network
- Tap OK
This will start learn mode on the Hub. It may take longer to receive all the network info and load all the devices. Check the other controller for confirmation of whether the transfer was successful.
Depending on the other controller, it may not have transferred the primary controller role to the SmartThings Hub, and the Hub may not be able to add new devices. To remove the Hub from the other network and reset it to default, follow the same steps above, but put the other controller in remove or exclude mode instead.
"Z-Wave Replace" is a special feature of the Z-Wave protocol that allows you to replace an unresponsive device with a new one of the same type. This allows you to physically replace a broken Z-Wave device without reconfiguring Automations associated with it.
To remove and replace a Z-Wave device using the SmartThings app:
- From the Home screen, touch Menu () > Devices
- Select the failed Z-Wave device
- Touch More options ()
- Touch Replace device
- The Z-Wave protocol will first attempt to communicate with the failed device to confirm unresponsiveness. This process can take several seconds
- Once the device is determined to be unresponsive, the Hub will search for the replacement device
- When the Hub is searching and indicates the device is ready to be replaced, perform the replacement device's connection (or "inclusion") process. This process is specific to the device. If your device is compatible with SmartThings, search our support center for connection instructions, or consult the device's manual
