ZigBee device is not working with Samsung SmartThings hub

If your sub hub is creating a new network rather than extending your existing network, you have probably created a Double NAT (Network Address Translation). There are two things you can try to resolve the problem.

If SmartThings experiences problems, you should report the issue to SmartThings Support so the developers can analyze it. You can also send a log file when the Wi-Fi Hub has issues to help improve its performance.

If you have multiple smart devices of the same type, changing the name can come in handy. For example, if you have a smart bulb in your living room and your kitchen, you'll want to know which is which, so you can control the right one every time. Fortunately, you can customize the name of your smart devices in the SmartThings app.

SmartThings has two types of notifications: traditional notifications that appear in your Notification panel and activity notifications that appear in the SmartThings app. You can manage both types of notifications depending on what you'd like to see.

If you are experiencing some trouble with your SmartThings Hub, such as devices not responding, sometimes a simple reboot can resolve the issue. However, the process depends on what kind of SmartThings hub you have.
