If the battery-powered device works fine on the local network but cannot be accessed from external networks, it may be due to network settings or router configurations.
You can try the following methods to resolve this issue:
Check router settings: Ensure that your router is properly configured for port forwarding or port mapping to allow access to your device from external networks. You may need to configure the router to allow the device to communicate through specific ports for remote access.
Check firewall settings: Make sure that your firewall or security software is not blocking external access to the device. You may need to add exceptions or allow-list entries in the firewall to permit communication with the device.
Use Dynamic DNS (DDNS) service: lf your device hasa dynamic IP address and your router supports Dynamic DNS (DDNS) service, you can use DDNS to map thedevice’s dynamic lP address to a fixed domain name. This allows you to access the device via a domain name, unaffected by lP address changes.
By trying these methods, you may be able to resolve the issue of the battery-powered device being inaccessible from external networks, enabling remote access and monitoring.
