Welcome @1231 to the Forum.

Have you carried out a search for Teltonika on the Forum. There are several threads describing communication between Node-RED and Teltonika devices.

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

A quick search shows [this thread](https://discourse.nodered.org/t/tcp-reply-to-teltonika-rutx11-modem/26499/11), which might help. You also might want to read your Teltonika (insert Device Name here), to see what communications options are available to you.
