Hello Slord,
Good day. Thank you for the question.
RMS is used only for the Teltonika Networking devices. So in this case, it cannot be used for FMB640 or FMB140 as the monitoring system. However, if you require a monitoring for FMB640 and FMB140, you may use TAVL but you will need to raise a query on VIP Helpdesk or contact your distributor/Sales Manager.
If you don't have any contacts with our Sales managers, please contact with them on our official website
https://teltonika-gps.com/ and click on the "Contact Us" button. When you click, please fill the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with description of your situation to info@teltonika.lt
As for the tracking of temperature data in the vehicle, I will suggest that you use a BLE Temperature sensor with FMB140 (currently FMB640 does not support BLE function). Please find the link on BLE temperature sensors here :

The instructions on how to connect the BLE temperature sensors can be found here -

Please go through this and let me know if you need further assistance.
Kind regards.
