Arrival sensor's plastic battery clips are broken

If your ZigBee device is not working with your hub, be sure to check the power to the device and the hub's network connection. However, it may be necessary to reset the ZigBee device and restart the hub to fix the problem.

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 will occasionally push firmware updates to active hubs to improve performance. You can check the hub's firmware version using the app or the IDE Portal.
