Hello @7wells,
Teltonika devices are primarily designed for industrial use, so home user/family functions haven’t been a priority. However, we appreciate your suggestion for bandwidth monitoring for individual devices and will consider it for future updates and features.
For now, you can try using the QoS service, which can be installed from System → Package Manager. While it won’t provide granular control over each device, it will allow you to set limits on certain interfaces. For example, you can create a separate wireless AP assigned to a new LAN interface and set limits specifically for that interface.
Best regards,
