Trb145 using 1.5gb of monthly 3G data Just to send two parameters humidity and temperature every minute. How can this data volume be reduced? It's resulting in very high data transmission cost.

Have tried disabling RMS connection but still not much difference in data usage.

Could it be because of zerotier VPN? Have disabled that as well now.

Hello,

There could be multiple reasons of data consumptions .

Could you please provide me a troubleshoot file in PM for the device so that i can check where is it being consumed , what features are enabled in the device.

You can download troubleshoot file in the System>Administration>Troubleshoot.

Also i think 1.5GB is not that much for a whole month.

Thank you.

Have a good day.

Regards,

Ahmed .

Thanks Ahmed. Sending the troubleshoot file.

I am using TRB145 to connect with a temperature and humidity sensor over modbus/RS485 and sending data to a server. Besides modbus, I just had NTP, zerotier and RMS enabled intially.

For the same application, I am using some other modems as well which use only 200MB in a month.

Hello,

Troubleshoot file was downloaded after the device was on for 4 minutes and in that time the device managed to consume very little data:

rmnet0   Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 

         inet addr:10.245.244.151 Mask:255.255.255.240

         inet6 addr: fe80::526e:8028:201f:b64e/64 Scope:Link

         UP RUNNING MTU:1500 Metric:1

         RX packets:267 errors:0 dropped:0 overruns:0 frame:0

         TX packets:405 errors:0 dropped:0 overruns:0 carrier:0

         collisions:0 txqueuelen:1000

         RX bytes:23804 (23.2 KiB) TX bytes:53537 (52.2 KiB)

To calculate: https://www.gbmb.org/kib-to-mb

I recommend getting a tcpdump file from the TRB145 when you notice huge data consumption.

From tcpdump file we can see what could potentially generate this kind of data. You can get the tcp dump file in 

System>Administration>Troubleshoot

TCP dump is a program used to capture packets moving through network interfaces. By default, the device does not store TCP dump information. You must enable 

TCP dump and save the changes before you can download the file.

Furthermore, you can visually see from where to where traffic goes, and maybe you could find where is data being used.

To check that navigate to Status -> Realtime Data -> Connections

Thank you.

Ahmed
