Hi everybody,

I have an interesting problem.

I tried to use my mobile router MR3020 to provide an internet connection for the smart hub in one of my properties, in order to monitor temperature and humidity.

I use a TP-Link MA-180 as the dongle to provide the 4G connectivity.

For the first hour everything goes fine - the router connects to the Internet, the hub reaches the cloud server and so I can access the hub, read the sensor's data, etc.

However after one hour with no traffic the connection is shut down. At this point, of course, I can't connect any more to the router. My explanation is that:

1. The mobile operator kills the connection after one hour because there's no traffic. There's no traffic because the hub doesn't send anything and unless I connect to the hub continuously the server doesn't poll ther hub
2. When I finally want to read the sensor data, say after a week, the cloud server tries to reach the hub using the IP address of the killed connection - and of course it fails as there's no active connection

Is my understanding correct?

Is there any way to make the hub reachable via a mobile router?

Any help appreciated.

Regards,

DMax
