Hi Dear :
This is SofaBaton, very glad to help you.
If the device cannot be searched after the network is configured, it may be that WiFi is being upgraded. After the distribution network, please kill the app first, and then do not enter the app. Plug in and unplug the hub power again. Wait 5-10 minutes before entering the app to upgrade the WiFi firmware, because after the distribution network is connected to the Internet, go back to the server to pull the latest WiFi firmware.
Remote control is custom 2.4G and does not require direct communication with the router. Wi-Fi in HUB, Manufacturer : Espressif Inc. Hostname: espressif
You can download an mdns search app, Android user can download "Service Browser", Apple user can download "Discovery-DNS-SD Browser"; If the phone and HUB are on the same LAN, open the app to search for a service "_x1hub._udp.", this is our HUB, tap it to see the IP address of the HUB (note that the MAC shown on the page is not the MAC of WIFI), you can confirm which is the HUB and check the MAC through the router management page;
