There are several possible reasons why your SONOFF TX T4EU1C WiFi Smart Wall Switch is staying "Offline":
1. Wi-Fi Connection: The switch may have failed to connect to your Wi-Fi network. Make sure you have entered the correct Wi-Fi password during the setup process.
2. Distance and Interference: If there is too much distance between the switch and your router, or if there are environmental factors causing interference, it may prevent the switch from connecting to the Wi-Fi network. Try moving the switch closer to the router and see if it connects. If not, consider troubleshooting any potential sources of interference.
3. Wi-Fi Network Compatibility: The SONOFF TX T4EU1C switch only supports 2.4GHz wireless networks. Make sure you are connecting to a 2.4GHz network and not a 5GHz network, as the switch does not support the latter.
4. MAC Address Filtering: If your router has MAC address filtering enabled, it may be blocking the switch from connecting to the network. Disable MAC address filtering in your router settings and try connecting the switch again.
5. Mobile Data Network: If none of the above methods solve the problem, you can try opening the mobile data network on your phone to create a Wi-Fi hotspot. Connect the switch to this hotspot and see if it connects. If it does, there may be an issue with your home Wi-Fi network.
If you continue to experience issues with the switch staying "Offline," it is recommended to consult the SONOFF TX T4EU1C WiFi Smart Wall Switch user manual or contact SONOFF support for further assistance.
