As a priority, please try to reset the hub manually. If your hub still won't add and the top indicator lights on the hub are on, we recommend checking the following: Assign the hub's MAC address a static IP address via the router's settings. The hub's MAC will begin with B0:CE:18. Confirm that your router produces a 2.4 GHz WiFi network and ensure the iOS or Android device you are using for setup is connected to the 2.4 GHz WiFi. Ensure all of the router's "ports" are open via your router's settings. You need to open port 6884. Double-check to make sure your router's firewalls are not blocking the hub. Make sure that your Sengled Home app and your phone's OS are up to date. Check if the SSID of your mobile device matches that of the Hub. If they do not match, please fix this.
