How to Troubleshoot: SmartThings Hub Offline? (2022)

SmartThings Hub Offline

It is hard to beat Samsung’s SmartThings Hub when it comes to hubs. WiFi, Z-Wave, and Zigbee devices (the three most popular smart home consumer technologies) are all compatible with the SmartThings Hub, making it an extremely powerful automation device.

I love the SmartThings platform and have a thermostat, garage door opener, alarm, and siren that are all compatible with it. A SmartThings hub failure may be a major inconvenience given its importance to my setup.

Here are some steps you may take to resolve the issue of your SmartThings Hub being unavailable:

  • Make sure your electricity is working properly.
  • Check your internet connectivity (for both wired and wireless connections).
  • Check your local network for errors.
  • Restart the Hub by pressing F5 on your keyboard.
  • Look for any signs of a platform outage.

Solution 1: Check The Power To Your SmartThings Hub

If the plug isn’t firmly inserted into the power socket, your SmartThings Hub may seem to be inactive on your device. It worked when I connected it into my 5GHz smart socket since there was a problem with my other plug. Make certain that everything is correctly connected, and your SmartThings Hub should be back online.

The presence of bad wiring in your Hub is another possible cause of improper powering of your Hub. Check all of the wires and make certain that they are properly secured. In addition, look for any loose connections or physical damage to the power wire that may have occurred.

If this is the case, the power cord should be replaced with a new one. It’s possible that doing so will assist in bringing your Hub back online.

Solution 2: Is Your SmartThings Hub Connected To The Internet?

If your Hub is linked to your network through WiFi, you should try connecting it directly to the router rather than to the network. Weak WiFi signals might be a symptom of a more serious problem with the router or Internet service provider.

Another option is to experiment with your WiFi network’s frequency ranges, toggling between the 2.4GHz and 5GHz channels.

However, although the SmartThings Hub is compatible with both 2.4GHz and 5GHz frequencies, your Hub may have difficulty picking up a 5GHz signal due to the lower range of the 5GHz band compared to the 2.4GHz band.

However, if your Hub is hardwired to your router, make sure the ethernet connection is in good working order. If the connection is correctly fastened on both ends and the Hub still seems to be offline, it is possible that the cable is faulty on one or both ends.

To remedy this problem, try connecting your computer to the internet using a different ethernet cable.

Solution 3: Local Network Connectivity For Your Smart Things Hub

The most typical cause for your Hub to become inaccessible is a problem with the local network connection. When your internet connection is inconsistent, it makes it more difficult for your Hub to remain connected.

The only way to resolve this is to contact your Internet service provider and have your connection repaired. If the issue continues, you may want to explore switching to a new Internet service provider or connecting to a different WiFi network if one is available.

Solution 4: Reboot Your SmartThings Hub

If your Hub remains inactive after attempting the remedies listed above, you may try restarting it by following the instructions outlined below:

  • Once the red button on the back of the Hub has been pressed, the Hub will reboot.
  • Hold the button down for a few minutes until the LED becomes solid green, indicating that the Hub has been restored to operational status.

If the previous technique does not work for you, you may attempt hard-rebooting your Hub by doing the following procedures:

  • Unplug the ethernet and power cords from their sockets. If your Hub is equipped with batteries (second generation or above), remove these as well.
  • Wait for about 30 seconds before reconnecting the batteries and cords to the computer.
  • Wait for the solid green light to illuminate before proceeding. Your Hub will be available as soon as this occurs.

Solution 5: Platform Outage Could Be The Issue If Nothing Else

According to the manufacturer, a major platform network failure in your area may result in the loss of service at your Hub. As a result, you are simply out of luck, and there is nothing you can do except wait for the network to re-establish its connection.

The platform status page may be consulted to see how things are progressing. Also available is real-time information on historical and current occurrences, as well as the option of subscribing to status updates at your leisure.


A security system’s Hub is analogous to a computer’s central processing unit (CPU). If your Hub becomes unresponsive, it has the potential to bring down your whole smart home.

It should be possible to restore your SmartThings Hub’s functionality by following the steps outlined above, as well as getting a knowledge of the various reasons for the problem.

It is possible that your SmartThings Hub is experiencing an internal issue if none of the suggestions above worked. It will be necessary for you to visit a Samsung Repair Center and speak with a professional in this situation.
