Virtual Serial Port on Linux with Elfin EE-10

Question

I want to connect the UART-Port of our central heater to my ProxMox-Server (LXC - Debian) over Web with Virtual Serial Port.

I bought this: https://www.aliexpress.com/item/4000945033185.html and connected it to the central heater and is reachable in the local network.

Since I have never done something in this direction I'm not exactly sure how to set up the connection and I hope someone can help me. In the Web-Interface of the device, I can set up different protocols (see screenshot).

Thank you for your help.

You need to know more about what the heater is writing and expecting on the serial port. Did you select the right serial baud rate for it?

Have you read the EE-10 IOT_Device_Series_Software_Funtion_20200623 guide (in Downloads tab)? One possibility for further debug is to select the telnetd mode and connect from Linux with telnet to the IP address of the device, default port 23. (Ensure your Linux firewall allows this).

It seems it should ask for login and password, as in the web page. Then you might get an EPORT> prompt which is the EE-10 cli. Enter Exit to enter transparent mode when what you type is sent directly to the heater, and what you see comes from the heater.
