If you can only control your device when your phone is connected to the same Wi-Fi network as the device, and not on other networks, it indicates an issue with your home's internet connection. The network may be experiencing connectivity problems with the external internet, causing your device to operate only within the local network.
To resolve this:
- Check Router Connectivity: Inspect the connection between your router and the external internet to ensure it is functioning properly.
- Ensure Stable Internet: Once you verify that the internet connection is stable, try controlling the device again.
